  • Title: Augmentation of synaptic responses in the dentate gyrus by daily electrical stimulation of the amygdala in cats.
    Author: Uno M, Ozawa N.
    Journal: Brain Dev; 1986; 8(4):451-3. PubMed ID: 3799914.
    Abstract:
    When the amygdaloid complex was electrically stimulated, polysynaptic evoked potentials were produced in the ipsilateral dentate gyrus of the hippocampal formation. Twenty-four hours after tetanic stimulation of the amygdala, the dentate response to single test pulses was found to be increased in amplitude. Stimulation trains presented at a rate of 1/day had a cumulative effect on the dentate evoked potential, which attained 5-10 times the original response in amplitude. The results imply that the efficiency of synaptic transmission in the amygdalo-hippocampal pathway can be modified, associated with amygdaloid kindling.
