  • Title: [Inhibition in association cortex neurons upon direct and transcallosal stimulation in the cat].
    Author: Mamonets TM.
    Journal: Neirofiziologiia; 1981; 13(2):133-41. PubMed ID: 6262665.
    Abstract:
    The experiments were performed on cats immobilized with myorelaxants. Depression of background activity or IPSP was recorded in neurons of the associative cortex in response to direct cortical and transcallosal stimulation. With the intensification of stimulation the duration of inhibition increased up to a certain limit for each studied cell. After this it still could increase if the number of the stimuli increased. Prolonged inhibition (up to several seconds) in response to a series of stimuli had the same nature as short inhibition about 20 ms evoked by a single stimulus. It was due to a prolonged hyperpolarizing postsynaptic potential. A suggestion is made that neurons producing monosynaptical inhibition in the associative cortex cells can be situated in the contralateral hemisphere.
