  • Title: [Conditioned and unconditioned alimentary reflexes in dogs upon electric stimulation of the orbital cortex].
    Author: Danilova LK.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1980; 30(2):272-8. PubMed ID: 7386024.
    Abstract:
    Changes in the value and dynamics of conditioned and unconditioned reflexes were studied in dogs under the action of unilateral low- (1 pulse/sec) and high-frequency (100 pulse/sec) stimulation of the orbital cortex. The low-frequency subthreshold stimulation elicited a significant decrease both in spontaneous (in the intervals between conditioned stimuli) and conditioned secretion, prolonged the latencies of the conditioned alimentary reflexes and practically did not influence the value of unconditioned reflexes. The high-frequency stimulation had a more deep inhibitory effect on the spontaneous and conditioned secretion and prolonged the latencies. The unconditioned secretion tended to increase. The low-frequency stimulation disinhibited the conditioned inhibition (both differentiation and extinction); the high-frequency stimulation had no disinhibitory effect on the differentiation.
