The aim of this doctoral dissertation was to follow the impact of ketamine/diazepam and pentobarbital anesthesia on the EEG microstructure and respiratory pattern during anesthesia, and on the post-anesthesia sleep/wake states architecture and transition structure, EEG microstructure across sleep, and all the sleep state episodes dynamics in the physiological condition, as well as during the PPT cholinergic neuropathology (the experimental model of Parkinson’s disease cholinergic neuropathology). Ketamine/diazepam anesthesia induces more alterations in the EEG microstructure and respiratory pattern than does the pentobarbital anesthesia in the PPT lesioned rats. In addition, the equal time required to establish an anesthetized state in the PPT lesioned vs. control rats, and the long-term suppressive effect on augmented NREM beta and theta amplitudes (the hallmarks of PPT cholinergic neuronal loss in rat) suggest ketamine/diazepam anesthesia as potentially more beneficial both for anesthesia induction and for post-anesthesia NREM sleep in the surgical procedures of the elderly, and Parkinson’s, and Alzheimer’s patients. In contrast to the ketamine/diazepam anesthesia the pentobarbital anesthesia is much more beneficial for the post-anesthesia REM sleep in physiological conditions as well as during the PPT cholinergic neuropathology on the basis of: the long-lasting REM sleep and transition structure disorders in physiological controls, induced by the ketamine/diazepam; the abolishing effects of both anesthetic regimens on the post-anesthesia prolonged REM/REM1 sleep and on their EEG microstructure disorders in the PPT lesioned rats; the abolishing effect of pentobarbital on the increased NREM/REM/NREM transitions, caused by the PPT lesion; and the equal EEG microstructure during stable pentobarbital anesthesia in the PPT lesioned rats versus controls.
