  • Title: [Effect of strychninization of the visual cortex on evoked activity in the rabbit lateral geniculate body].
    Author: Lazareva NA.
    Journal: Neirofiziologiia; 1976; 8(5):459-66. PubMed ID: 980166.
    Abstract:
    Changes in responses of low-frequency and high-frequency LGB neurons were studied on anesthetized and paralyzed rabbits after strichninization of the visual cortex. It was found that in the group of low-frequency neurons the average discharge frequency of responses increased and latencies decreased indicating a dominance of corticofugal facilitation. On the contrary, in the group of high-frequency neurons the average discharge frequency of responses decreased and latencies increased. This suggests a dominance of corticofugal inhibition. The existence of reciprocal corticofugal influences on the neurons of different components of the visual pathways is assumed.
