Spectral characteristics of activity of the rabbit neo cortex and the dorsal hippocampus following coagulation of the septum






Zhurnal Vysshei Nervnoi Deyatel'nosti Imeni I P Pavlova 30(2): 382-391

Spectral characteristics of activity of the rabbit neo cortex and the dorsal hippocampus following coagulation of the septum

Spectral characteristics of the activity of the visual and motor neocortical zones and of the dorsal hippocampus were examined in intact alert rabbits and rabbits subjected to an electrolytic ablation of the septum. Following septum coagulation, the spectrograms of these formations were characterized by considerable reduction of power spectra within the .theta.-range, discordance of .theta.-frequencies in the spectrograms of the simultaneously recorded activity of the studied formation and an enhancement of power spectra within the higher frequencies range. In the above brain regions facultative generators of the .theta.-activity apparently function under a synchronizing influence of the septum.
