Cerebellar involvement in cognitive functions has been revealed in
numerous anatomical, clinical and neuroimaging studies and several
hypotheses about potential the role of the cerebellum in higher level
brain function have been established. The aim of this study was to show
involvement of the cerebellum in simple cognitive tasks. For this
matter, we contrasted two tasks from the same semantic domain with
specific cognitive content and level of practice: counting forward and
counting backward. Twelve volunteers participated in this fMRI study and
they were asked to perform both tasks within the same number range (1 to
30 and vice versa). Results showed greater activation in the right
cerebellum for the task of counting forward than for counting backward,
while for counting backward greater activation was found in prefrontal
cortex, supplementary motor area, and anterior cingulate of both
hemispheres. Our results correlate with already established hypotheses
about cerebellar role in precise and smooth control, not only in
well-trained motor but in well trained cognitive tasks as well.
