AB  - Recently, thermal imaging has become an important sensing technology in biological investigations [1]. Here we present a thermo-optical analysis of a longhorn beetle’s exoskeleton (cuticle) in the visible and mid-infrared part of the spectrum. The insect (Morimus funereus, family Cerambycidae, shown in Fig. 1) possesses several prominent black patches on its hardened forewings (the elytrae). The patches, covered with dense, black, micron-sized hairs, were the subject of our investigation. Thermographic measurements were done by using a thermal camera, operating in the spectral range from 7.5 to 13 μm. We have found that deep black colour of the patches comes, not only from pigments (melanin), but from the underlying structure, and has a thermoregulatory effect [2]. Analysis has shown that these structures maximize absorption in a visible and minimize radiative thermal losses, thus enabling the insect to keep the heat. This particular property could be an inspiration for development of biomimetic coatings which will diminish thermal dissipation through radiation. This is in contrast to coatings inspired by an African desert ant, whose cuticle minimizes absorption in the visible and maximizes the radiative losses [3]. Principles discovered in both insects are well adjusted to different environments – a cold one, where it is important to keep heat, and a hot one, where it is necessary to dissipate thermal energy as efficiently as possible.

AB  - Purpose: Extremely low frequency (ELF) magnetic fields are essential
   ecological factors which may induce changes in many organisms. The aim
   of this study was to examine the effects in Drosophila subobscura
   exposed for 48 h to ELF magnetic field (50 Hz, 0.5 mT) at different
   developmental stages.
   Materials and methods: Egg-first instar larvae developmental stage of D.
   subobscura isofemale lines was exposed to ELF magnetic field, and
   fitness components (developmental time, developmental dynamics,
   viability and sex ratio) and locomotor activity of three-day-old males
   and females were monitored. Also, just eclosed D. subobscura isofemale
   adults were exposed to ELF magnetic field and their locomotor activity
   was monitored just after.
   Results: ELF magnetic field shortens developmental time, increases
   viability and does not affect sex ratio of D. subobscura. No matter
   which developmental stage is exposed, ELF magnetic field significantly
   decreases locomotor activity of adult flies, but after exposure of just
   eclosed adults observed change lasts longer.
   Conclusions: Applied ELF magnetic field modifies fitness components and
   locomotor activity of D. subobscura. Observed effects can be attributed
   to the influence of magnetic field on different stages of development
   where the hormonal and nervous systems play important role in the
   control of examined parameters.

AB  - Purpose: The aim of this study was to investigate the influence of extremely low frequency magnetic field (ELF-MF) on different behavior parameters (locomotion, stereotypy, and immobility) in 3- and 10-month-old male Mongolian gerbils. Materials and methods: The animals were continuously exposed to ELF-MF (50 Hz; 0.1, 0.25 and 0.5 mT) for seven days. Their behavior was monitored for 60 min in the open field after the 1st, 2nd, 4th, and 7th day of exposure (immediate effect), and three days after ELF-MF exposure had been ceased (delayed effect). Results : In 3-month-old gerbils, exposure to ELF-MF (0.1, 0.25 and 0.5 mT) increased motor behavior (locomotion and stereotypy), and consequently decreased immobility. Additionally, ELF-MF had delayed effect (except 0.25 mT) on stereotypy and immobility. In 10-month-old gerbils, ELF-MF of 0.1, 0.25 and 0.5 mT induced decrease, slight increase, and pronounced stimulation of motor behavior, respectively. Regardless of magnetic induction value, increased motor behavior was observed three days after ELF-MF exposure has been ceased (delayed effect). Conclusions: It can be proposed that the specific temporal patterns of ELF-MF-induced motor behavior changes in 3- and 10-month-old gerbils are a consequence of age-dependent morpho-functional differences in the brain structures responsible for a control of motor behavior.

AB  - Purpose: To compare the effects of repeated exposure to extremely low frequency-modulated microwaves (ELF-MW) on cortical and hypothalamic electroencephalograms (EEG). Materials and methods: In 10 freely moving rats with carbon electrodes implanted into the cortex and dorsomedial hypothalamus, averaged frequency spectra (0.5-30 Hz) of the EEG were studied for five consecutive days either under sham exposures (five rats) or under mixed sham/MW-exposures (five rats). The rats were exposed to ELF-MW (915 MHz, 20-ms pulse duration, approximately 0.3 mW/cm(2), 4 Hz) intermittently (1-min 'On', 1-min 'Off') for 10 min (specific absorption rate, SAR, approximately 0.7 mW/g on average) several times per day, with 10-min pre- and post-exposure periods. Results: In baseline EEG, the activities of 3.2-6.0 Hz and 17.8-30.5 Hz dominated in the cortex and of 6.0-17.8 Hz in the hypothalamus. This cortical-hypothalamic imbalance was relatively stable at sham-exposures and insensitive to ELF-MW in all frequency ranges but one. ELF-MW increased the beta(2) (17.8-30.5 Hz) level in the hypothalamus to a greater extent than in the cortex, causing significant diminishing of the initial EEG bias between them. Moreover, a cumulative phenomenon under repeated exposures to ELF-MW was revealed. Conclusions: These results are in line with evidence that repeated low-level exposure to ELF-MW affects brain functioning and provide an additional approach when analysing underlying mechanisms.

Materials and methods: In 10 freely moving rats with carbon electrodes implanted into the cortex and dorsomedial hypothalamus, averaged frequency spectra (0.5-30 Hz) of the EEG were studied for five consecutive days either under sham exposures (five rats) or under mixed sham/MW-exposures (five rats). The rats were exposed to ELF-MW (915 MHz, 20-ms pulse duration, approximately 0.3 mW/cm(2), 4 Hz) intermittently (1-min 'On', 1-min 'Off') for 10 min (specific absorption rate, SAR, approximately 0.7 mW/g on average) several times per day, with 10-min pre- and post-exposure periods. Results: In baseline EEG, the activities of 3.2-6.0 Hz and 17.8-30.5 Hz dominated in the cortex and of 6.0-17.8 Hz in the hypothalamus. This cortical-hypothalamic imbalance was relatively stable at sham-exposures and insensitive to ELF-MW in all frequency ranges but one. ELF-MW increased the beta(2) (17.8-30.5 Hz) level in the hypothalamus to a greater extent than in the cortex, causing significant diminishing of the initial EEG bias between them. Moreover, a cumulative phenomenon under repeated exposures to ELF-MW was revealed. Conclusions: These results are in line with evidence that repeated low-level exposure to ELF-MW affects brain functioning and provide an additional approach when analysing underlying mechanisms.",

AB  - Interes za istraživanja magnetobioloških i biomagnetnih fenomena u različitoj meri se provlači kroz istoriju nauke od najranijih dana do danas. Biološki efekti magnetnih polja različitih karakteristika ispitivani su kod živih bića na svim nivoima biološke organizacije, od subćelijskog i ćelijskog nivoa do visokoorganizovanog višećelijskog sistema i populacija. U eksperimentalnim studijama korišćena su konstantna (permanentna, stalna) magnetna polja različitih intenziteta, kao i promenljiva magnetna polja najširih frekventnih opsega od ekstremno niskofrekventnih (ENF), čak ispod vrednosti od 1 Hz, preko ekstremno visokofrekventnih u IC, vidljivom i UV delu spektra, do jonizujućih elektromagnetnih polja.
U početku formiranja ideje o magnetobiološkoj laboratoriji u okviru IBISS-a, efekti magnetnih polja praćeni su na različitim model sistemima. Osnovno pitanje koje se nametalo u ovim istraživanjima je bilo kako različiti organizmi reaguju na prisustvo dodatnih magnetnih polja, kao faktora spoljašnje sredine, čiji intenziteti višestruko prevazilaze vrednosti prirodnog magnetnog polja.
Na modelu mikrobiološke oksidacije Fe++ bakterije Thiobacillus ferrooxidans, rezultati naših istraživanja su pokazali da se na 13ºC kultura ove bakterije u tečnoj Leathen-podlozi razvija sporije u uslovima izlaganja konstantnom magnetnom polju od 104 mT i 231 mT [14,22]. Za razliku od konstantnog magnetnog polja, izlaganje kultura ove vrste bakterija promenljivom magnetnom polju (50 Hz, oko 6 mT) ubrzava aktivnost populacije bakterija [25]. Na ovom modelu je jasno uočeno da efekat zavisi od intenziteta magnetnog polja i koncentracije gvožđa u podlozi.
Na modelu ponašanja riba sunčanice Lepomis gibbosus i babuške Carassius gibelio, uočena je izrazita individualna varijabilnost u motornom ponašanju ovih riba koje su višekratno (1.5h odnosno 8h dnevno u toku 40 dana) izlagane konstantnom magnetnom polju od 20 mT [14]. I pored toga, svođenjem na prosek motorna aktivnost ovih riba je bila znatno smanjena u odnosu na kontrolne jedinke.
Dalja istraživanja su se usmerila na procese razvića. U tom pogledu su se pokazale vrlo pogodne populacije larvi pčela Apis mellifera, uzete sa saćem iz košnice, koje su bile u fazi zatvorenih legala. Larve pčela izložene konstantnom magnetnom polju prosečne vrednosti od 122 mT razvijale su se statistički značajno brže od onih u kontrolnim uslovima [19]. Efekat ubrzanog razvića larvi insekata u konstatnom magnetnom polju uočen je i kod vrsta Drosophila melanogaster i Tenebrio molitor [20,21], kao i kod paličnjaka Baculum extradentatum izloženih konstantnom magnetnom polju (320 mT) i promenljivom magnetnom polju (50 Hz, 6 mT) [7]. Za razliku od pomenutih insekata, promenljivo magnetno polje (50 Hz, 6 mT) značajno usporava metamorfozu kućne muve (Musca domestica L.) na temperaturi od 19ºC i 24ºC [27]. Pored toga, magnetno polje pomenutih karakteristika produžava dužinu života odraslih jedinki kućne muve na temperaturi od 24ºC. Preživljavanje i masa larvi kućne strižibube (Hylotrupes bajulus L.) su povećani kod jedinki koje su izlagane konstantnom magnetnom polju od 98 mT u odnosu na kontrolnu grupu [24].
Na osnovu ovih zapažanja, postavljeni su ogledi sa ciljem da se otkrije eventualni efekat spoljašnjeg magnetnog polja na genetičke mehanizme. Tako je ustanovljeno kod Drosophila melanogaster da je varijabilnost unutar grupa mušica izloženih konstantnom magnetnom polju prosečne vrednosti od oko 150 mT znatno veća nego kod onih u kontrolnim uslovima [15,16]. Kada se podaci o preživljavanju pojedinih grupa mušica razdvoje na kategorije preživljavanja (letali, semiletali, subvitali, normali, supervitali) dobija se nova informacija o preraspodeli ovih efekata vezanih za drugi par hromozama među kategorijama kod kontrolnih i tretiranih jedinki Drosophila melanogaster. Ovaj efekat konstantnog magnetnog polja se održavao kroz tri praćene generacije vinskih mušica.
Da su genetski mehanizmi podložni promeni usled delovanja magnetnog polja pokazala su istraživanja u kojima su praćeni veličina i bilateralna asimetrija krila kod Drosophila melanogaster izloženih konstantnom magnetnom polju od 35 mT kroz 6 uzastopnih generacija [26]. Pokazano je da se pod dejstvom magnetnog polja pomenutih karakteristika smanjuje veličina krila Drosophila melanogaster, dok bilateralna asimetrija krila kao pokazatelj razvojne nestabilnosti nije značajno povećana.
Elektromagnetna polja ENF predstavljaju još jedan od abiotičkih faktora koji je sve prisutniji u životnoj sredini. Akutno ili hronično izlaganje elektromagnetnim poljima, čije vrednosti samo nekoliko puta prevazilaze vrednosti zemljinog magnetnog polja, može predstavljati stres za organizam u mnogobrojnim biološkim aspektima. U prisustvu elektromagnetnog polja (50 Hz, 0.25 mT), koje je u širokoj primeni u domaćinstvu, industriji i saobraćaju, dolazi do povećanja veličine tela jedinki Drosophila subobscura oba pola, dok nižu razvojnu stabilnost u ovim uslovima pokazuju samo ženke i to za širinu krila [10]. Ovi rezultati ukazuju da izlaganje ovakvom magnetnom polju može imati stresogeni efekat sa određenim biološkim posledicama.
Novija istraživanja koja se odvijaju u okviru Laboratorije za magnetobiologiju IBISS-a pokušavaju da daju odgovor na pitanje koji su osnovni principi percepcije spoljašnjih magnetnih polja, kao i mehanizmi odgovora biosistema na dodatni faktor spoljašnje sredine, kako u normalnim tako i u izmenjenim fiziološkim stanjima. U tom cilju se koriste različiti organizmi i njihovi izolovani sistemi (Helix pomatia, Baculum extradentatum, Cerambyx cerdo, Tenebrio molitor, Morimus funereus, Ratus ratus, Meriones unguiculatus,...) i različite tehnike (od ekstraćelijske registracije potencijala, preko histološke i biohemijske obrade uzoraka tkiva, do finih mehanizama ponašanja i matematičke obrade dobijenih signala).
Na razrađenom modelu registrovanja bioelektričnih potencijala poreklom iz izolovane subezofagijalne ganglije (Br i N1 neuroni) vinogradarskog puža Helix pomatia, testiran je efakat konstantnog magnetnog polja od 2.7 i 10 mT. Pokazano je da magnetno polje od 2.7 mT prouzrokuje promene u amplitudi i trajanju akcionog potencijala Br neurona, dok magnetno polje od 10 mT menja potencijal mirovanja, amplitudu, frekvencu i trajanje akcionog potencijala Br neurona [9]. Rezultati ovih istraživanja ukazuju da su uočeni efekti na Br neuronu zavisni od intenziteta magnetnog polja. Za razliku od Br neurona, bioelektrični parametri mereni sa N1 neurona nisu se značajno menjali u prisustvu magnetnog polja pomenutih karakteristika.
U daljem traganju za primarnim mehanizmima percepcije magnetnih polja kod živih sistema, a imajući u vidu prethodne naznake da bi to mogao biti centralni nervni sistem, pristupilo se sličnim elektrofiziološkim istraživanjima na znatno komplikovanijim moždanim ganglijama kod insekata. Po prvi put registrovana je spontana bioelektrična aktivnost iz antenalnog regiona mozga strižibube Morimus funereus. Nakon izlaganja glavenog regiona adulta konstantnom magnetnom polju od 2 mT, uočena je individualna osetljivost organizama na spoljašnja magnetna polja, koja se ogledala u promenama neuronske aktivnosti tokom i nakon delovanja primenjenog magnetnog polja [28].
Da bi se potkrepili podaci o pretpostavci da je nervni sistem struktura primarno odgovorna za reakciju organizama na različite spoljašnje ekološke faktore uključujući i magnetna polja, posvetila se pažnja i analizi neurosekretornog sistema insekata. Pokazano je da jako statičko magnetno polje (320 mT) utiče na citološke karakteristike i aktivnost protocerebralnih A2′ neurosekretornih neurona i corpora allata kod lutki Tenebrio molitor [11,12]. Nešto ranije, efekti promenljivog ENF magnetnog polja (50 Hz, 20 mT) na aktivnost neurosekretornih neurona i corpora allata uočeni su i kod larvi strižibube Cerambyx cerdo [8].
Uticaj magnetnih polja na biohemiju i fiziologiju ćelija ogleda se i kroz promene u produkciji slobodnih radikala i antioksidativnoj odbrani. Kod hemimetabolnog insekta Baculum extradentatum čije se embrionalno razviće odvijalo u prisustvu konstantnog (320 mT) i promenljivog (50 Hz, 6 mT) magnetnog polja uočeno je povećanje aktivnosti enzimskih (superoksid dismutaza, katalaza) i neenzimskih (glutation) komponenti antioksidativnog sistema [29].
Najzad, istraživanja na modelu insekata u kojima su ispitivani efekti magnetnih polja na motorno ponašanje strižibube Morimus funereus su ukazala na promene u motornoj aktivnosti mužjaka i ženki nakon izlaganja ENF (50 Hz, 2 mT) magnetnom polju [18].
Kod evolutivno viših organizacionih sistema (glodari), uticaj kratkotrajnog i dugotrajnog izlaganja magnetnim poljima praćen je na nivou biohemijske analize parametara oksidativnog stresa, koncentracije nukleotida i aktivnosti receptora u izolovanim strukturama mozga, kao i registracije EEG zapisa i motornog ponašanja. Najznačajniji rezultat biohemijskih istraživanja parametara oksidativnog stresa je da izlaganje pacova (Ratus ratus) i pustinjskog miša (Meriones unguiculatus) ENF magnetnom polju (50 Hz, 0.5 mT) utiče na oksido-redukcione procese u mozgu ispitivanih životinja [2,5,6]. Akutno i hronično izlaganje magnetnom polju pomenutih karakteristika dovodi i do promena u koncentraciji nukleotida (IMP, cAMP, ATP), kao i aktivnosti serotoninskih i dopaminskih receptora u izolovanim strukturama mozga pacova [1,4]. Eksperimenti bazirani na registraciji elektrofizioloških zapisa iz mozga pacova su ukazali na sposobnost magnetnih polja da modifikuju aktivnost neurotransmiterskih sistema [30]. Pored toga, spoljašnja ENF magnetna polja modulišu motorno ponašanje eksperimentalnih životinja (Ratus ratus, Meriones unguiculatus), pri čemu karakter promena zavisi od fizičkih karakteristika polja (intenzitet, dužina izlaganja) i individualnih osobenosti organizama (vrsta, starost, funkcionalno stanje) [1,2,3,13,17,23].

Rezultati svih ovih istraživanja nedvosmisleno pokazuju da „veštačka“ magnetna polja, kao ekofiziološki faktor, indukuju strukturne, biohemijske i funkcionalne promene kod evolutivno različitih organizama.

AB  - The effect of magnetic field on the physiology of neuroendocrine system and developmental processes in insects are poorly examined. Insect neurohormones which are master regulators of physiological, metabolic processes, homeostasis uphold, are mainly synthesize in neurosecretory neurons of protocerebral part of insect brain. The products of neurosecretory neurons in the medial part of insects' protocerebrum include neurohormones which participate in regulation of the synthesis of the main morphogenetic hormones. 
The activity of protocerebral medial A2 neurosecretory neurons were investigated in 4th instar Lymantria dispar larvae, which were exposed to the acute effect of constant magnetic field (CMP) and extreme low frequency magnetic filed (ELF MF). Larvae were kept for three days in constant magnetic field (average magnet induction of 235 mT) and extreme low frequency magnetic filed (average magnet induction of 6 mT). 
The size of A2 neurosecretory cells and the size of their nuclei were decreased after the exposure to ELF MF. Constant magnetic filed induced the increase in number of A2 neurosecretory cells with high amount of large grained neuroseretory material. Our results indicate that ELF MF reduces the activity of A2 neurosecretory neurons, a possible location of the synthesis of insulin-like peptides, which have a role in control processes of moulting program, but probably also in stress response phase in which the energy for physiological reactions is obtained.

AB  - The neuroendocrine system of insects consists of neurosecretory neurons located in the brain and ventral nerve cord. Neurohormones are synthesized and secrete in neurosecretory neurons. Neurohormones represent the main regulators of physiological and metabolic processes including secretion of hormones that regulate molting, metamorphosis, reproduction, stress responses and homeostasis in insects. The dorsolateral neurosecretory neurons of insect protocerebrum are known to be a site of synthesis of allatostatins and large form of prothoracicotropic hormone, the regulators of metabolic and morphogenetic processes in insects. 
The effects of constant magnetic (average magnet induction of 235 mT) and extreme low frequency (average magnet induction of 6 mT) magnetic field on morphometric characteristics of L2' neurosecretory neurons in 4th instar gypsy moth larvae were investigated. Larvae were reared from first until third day of 4th instar on artificial diet and in constant and extreme low frequency magnetic field. 
The acute effect of constant magnetic field on morphometric characteristics of L2' neurosecretory neurons in gypsy moth larvae were not detected. The extreme low frequency magnetic field led to a decrease in L2' cells size. Both type of magnetic fields induced an increase in amount of neurosecretory material. After the exposure to constant magnetic field the neurosecretory material was medium size grained, while after the exposure to extreme low frequency magnetic filed the large size grained neurosecretory material was dominantly presented. In this paper the reduction in L2' neurosecretory activity was obtained. It is known that these cells synthesize neurohormones involved in morphogenesis, and their level is decreased in the middle of larval instar and also when the instar is prolonged which be one of stress response action.

AB  - In addition to morphological changes, global cerebral ischemia leads to functional changes that can be assessed by behavioral examination. The purpose of this study was to investigate the impact of the duration of global cerebral ischemia on the time course of a comprehensive set of motor behaviors in Mongolian gerbils. The common carotid arteries of gerbils were occluded either for 5 min, 10 min, or 15 min. Gerbil motor behavior was recorded in the open field at 24 h, 48 h, 4 days, 7 days, 14 days, 21 days, and 28 days after reperfusion. Each session lasted for 60 min and was composed of six intervals of 10 min. Our results revealed that ischemic gerbils quickly develop locomotor and stereotypic hyperactivity, with the expected decrease of resting time. The most evident effect was observed in gerbils submitted to a 15 min ischemia, whose locomotor activity returned to nearly normal values after 7 days. In contrast, the duration of global cerebral ischemia had no effects on rearing, clockwise, or counter-clockwise rotation. These findings indicate that exposure to global cerebral ischernia induces changes in locomotion, stereotypy, and resting time. The magnitude and duration of these effects depend on the duration of ischernia.

AB  - Metamorphosis time (pupa to adult eclosion time) and adult lifespan were observed in an alternating, sinusoidal, magnetic field, and compared to control. Pupae of the housefly, Musca domestica (Diptera), of approximately the same age were chosen randomly (groups of 50
individuals) and individually placed in separate glass tubes (70 mm × 11
mm) without food. The group exposed to an electromagnet (50 Hz, 6 mT) with poles of 9.3 cm × 4.8 cm (area 44.6 cm2), spaced at 7.2 cm, was placed with the magnet at a sufficient distance from the control group where the experimental magnetic field effects were not detected. The experiments were carried out successively at temperatures of 19°C and 24°C, and a 12 h light/12 h dark regime, with a controlled 60–70% relative humidity. The results show that the magnetic field significantly slowed down metamorphosis at both temperatures. The adult lifespan in the magnetic field at 24°C was statistically significantly extended with respect to control, whereas the same lifespan in the magnetic field at 19°C showed no statistically significant shortening.

AB  - The effects of chronic (7 days) exposure to an extremely low frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) on spontaneous and amphetamine-induced (1.5 mg/kg, i.p.) locomotor and stereotypic activities in adult rats were examined by open field test for 2 h on exposure days 1, 3, and 7. After 1 day of exposure to ELF-MF, the spontaneous locomotor activity was increased clearly at the first hour of observation and significantly at the second one as compared to the corresponding values in other series with ELF-MF and sham-exposed animals. After 7 days of exposure to ELF-MF, an amphetamine enhancing effect on the locomotor activity was significantly reduced at the second hour of observation as compared to that in 1-day- and sham-exposed rats treated with amphetamine. In contrast to the locomotor activity, the amphetamine-induced stereotypic behaviour in 7-day pre-exposed rats was significantly reduced at the first hour versus sham-exposed rats. While at the second hour of observation this effect was significant as compared to 1- and 3-day exposed animals (but not sham-exposed rats). Our results indicate that an extremely low frequency magnetic field is able to affect differently two types of behaviour, which are dependent on both the time course of exposure and the imbalance in the brain mediatory systems.

AB  - The effects of short-term (15 min) pre-exposure of rats to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 6 mT) on their motor (locomotor and stereotypic) activity induced by D-amphetamine sulphate (AMPH) at different doses (0.5, 1.5 and 4.5 mg/kg, i.p.) were studied in the open field test. In saline-treated rats both parameters of motor activity were unaffected by ELF-MF irradiation. The rats pre-exposed to ELF-MF and injected with the lowest dose of AMPH showed the same locomotor activity as control animals, while their stereotypic behaviour was significantly elevated. ELF-MF in combination with AMPH at higher doses significantly enhanced motor activity when compared with values obtained in both control and combined experiments with the lowest dose of the drug. However, only combined locomotor effect at the middle dose of AMPH was significantly greater than those observed in corresponding experiments with AMPH alone. These results demonstrate that acute short-term exposure to ELF-MF is able to modify a motor activity in dependence on the extent of AMPH-induced neurotransmitter imbalance.

AB  - Purpose: To compare in the electroencephalogram of rats the effects of scopolamine (an acetylcholine receptor antagonist) alone and after repeated exposure to low‐level microwaves modulated at extremely low frequency. Materials and methods: Averaged frequency spectra (0.5–30 Hz) of the electroencephalogram were studied in freely moving rats with carbon electrodes implanted into the somatosensory cortex. The rats were repeatedly (3 days, 30 min day−1) exposed to low‐intensity
(≅0.3 mW cm−2) microwaves (915 MHz, 20‐ms pulse duration), amplitude modulated (square‐wave) at extremely low frequency (4 Hz). Results: The exposure to extremely low frequency microwaves alone significantly enhanced the fast electroencephalographic rhythms (18–30 Hz). This effect was observed neither in subsequent sham‐exposure experiment nor in radiation‐naïve animals. In the microwave‐exposed rats, scopolamine
(0.1 mg kg−1, subcutaneously) did not cause a slowing in the electroencephalogram that was shown in non‐exposed rats. A similarity between the scopolamine‐induced electroencephalogram effect in the microwave‐exposed rats and that of physostigmine (enhancing the acetylcholine level in the brain) in radiation‐naïve animals was noted. 
This paradoxical phenomenon stimulates new experimentation for understanding its mechanism(s). Conclusions: The data obtained provide additional evidence that repeated low‐level exposure to extremely low frequency microwaves can modify an activity of cholinergic system in the brain.

Refeeding resulted in a compensatory increase of larval growth. Feeding and refeeding with qualitatively different nutritive substrates affected both quality and quantity of midgut and brain proteins. The observed differences suggest the possible switching of enzyme isoforms in M. funereus midgut and changes in synthesis secretion of neurohormones, depending on food presence and its nutritional value.
