  • Title: [Primary inhibitory responses of neurons of a chronically isolated band of auditory cortex to intracortical stimulation].
    Author: Taranenko VD, Semik LI, Rabtsevich MA.
    Journal: Neirofiziologiia; 1984; 16(2):152-61. PubMed ID: 6330580.
    Abstract:
    The reactions of 579 neurons to intracortical stimulation of an auditory cortex slab (three weeks after its isolation) were studied intracellularly in three series of experiments on cats. The distances between stimulating and recording electrodes were 0.5, 1.0 and 2.0 mm. It was shown that 67.7% of neurons responded to intracortical stimulation by primary IPSP, which is by 10% more than that in acute isolated slab. The distribution of neurons reacting by primary IPSP was analysed according to the depth of location in the isolated slab and to the duration of IPSPs and their latent periods depending on the distance between the point of stimulating and recording microelectrodes. Latent periods of IPSPs did not exceed 10 ms like in an acute isolated slab. Amplitude and duration of IPSP were in the same range as in acute isolated slab and intact auditory cortex of cat brain. The histological structure of the chronically isolated auditory cortex slab is described.
