[Electrical activity of the rat brain following antenatal hypoxia].

EEG and EPs in the visual and parietal neocortical areas and the hippocampus were studied in freely behaving rats at the age of two-three months after antenatal hypoxia. Increase of spectral power in delta and theta bands and its decrease in alpha and beta bands in the background EEG and in responses to a protracted light stimulation were observed in experimental animals in comparison to control ones. The most pronounced changes were observed in the parietal cortex and hippocampus.
