[Effect of amygdaloid stimulation on receptive field of "on" LGB neurons in rabbit].
With the aim of study of the effect of stimulating amygdaloid body (basal) on the responsive characteristics of the receptive field (RF) of on-response LGB neurons, electrophysiological experiments were performed on 37 New Zealand rabbits anaethetized with urethane and immobilized by flaxedil. Of the 117 recorded neurons, 47 showed changes in inresponse to light stimulation (facilitation or inhibition) and/or changes in RF configuration, although stimulation of amygdaloid body alone resulted in no visible change of the neuronal activities. The above results suggested that amygdaloid may modulate ascending visual information proccessing at thalami level by changing various combinations of the response characteristics of the on-response LGB neurons.
