Electrophysiological investigation of the role of the hippocampus in conditioned reflex activity of the lizard ophisaurus apodus


, : Electrophysiological investigation of the role of the hippocampus in conditioned reflex activity of the lizard ophisaurus apodus. Zhurnal Evolyutsionnoi Biokhimii i Fiziologii 20(3): 313-317

The effect of stimulation and electrolytic coagulation of different parts of the dorsal hippocampus on electrographic indices of positive and negative conditioned reactions was studied in the lizard, O. apodus. Stimulation of diffrent parts of the dorsal hippocampus is associated with preservation in some of the experiments, as shown by facilitation of EEG correlates of positive conditioned reactions in the brain hemispheres. During hippocampal stimulation differential inhibition is increased. After damage of the dorsal hippocampus EEG correlates of the conditioned positive reaction still persist. Experimental treatment of the hippocampal structures does not affect the behavior of animals. Non-specific pattern of hippocampal influences in reptiles is discussed.
