[Assessment of human regional cerebral circulation by venocclusive rheoplethysmoencephalography]

A possibility was shown of using the method of venocclusion rheoplethysmoencephalography (RPEG) for the assessment of the extent of changes in the cerebral circulation (CC) in individual regions of the cerebral hemispheres of a practically healthy man in various functional loads. The changes in the CC was recorded in per cent in respect to its initial background value. Data on the increase (by 114%) of the CC in the centralparietal region of the left cerebral hemisphere in movement with the right hand and on its reduction (by 45%) in sound stimulation. In the adjacent (temporal) region the changes in the CC were of other character.
