  • Title: [Dynamics of rabbit visual cortex neuron reaction to presentation of repetitive photic stimuli].
    Author: Polianskiĭ VB, Prokof'ev SK.
    Journal: Neirofiziologiia; 1978; 10(5):451-9. PubMed ID: 703898.
    Abstract:
    Responses of visual cortex neurons to repeated light flashes with frequency of 1 stimulus per 2.5 were investigated in rabbits. Two forms of response dynamics (according to the total number of spikes in the response) were found: "fast" and "slow". 5--15 stimuli were required for the stabilization of the responses of the first form and 50--100 stimuli for that of the second form. About 50% of all the neurons showed stable responses. Partial habituation of responses was revealed in 55--59% of the neurons, sensitizations of discharge in 25% and hump-shared type of the response in 17--20% of neurons. "Slow" dynamic modifications of the responses in most neurons were associated with modifications in the duration of the inhibitory phases in the responses.
