Abstract

Projections to the amygdala from various cortical and subcortical areas terminate in different nuclei. In the present study we examined long-term potentiation of synaptic transmission in the lateral or the basal amygdaloid nuclei by theta burst stimulation of thalamic vs. cortical sensory projections in the anesthetized rat. Although both the medial geniculate nucleus andthe dorsal perirhinal cortex have direct projections to lateral nucleus. only the thalamic stimulation induced long-term potentiation of field potentials recorded in the lateral nucleus. In contrast. cortical (ventral perirhinal cortex) but not thalamic stimulation induced long-term potentiation inthe basal nucleus. Since the thalamic pathway is believed to process simpie/unimodal stimulusfeatures, and the perirhinal cortex complex/polymodal sensory representations, the dissociation of long-term potentiation in lateral and basal nucleisuggests that the basal nucleus may serve as an amygdaloid sensory interface for complex stimulus information similar to the role of the lateral nucleus in relation to relatively simple representations. Thus plasticity of simple and complex representations may involve different amygdala inputs and circuits. (C) 2001 IBRO, Published by Elsevier Science Ltd, All rights reserved.
