One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus (MD) to frontal eye field (FEF) carries a corollary discharge about saccades made into the contralateral visual field. We inactivated the MD relay node with muscimol in monkeys ...

The present report investigated the involvement of primate nigro-thalamo-cortical projections in discrimination of visual signals with behavioral meaning. We tested the extracellular unit activity of mediodorsal (MD) and ventral anterior (VA) thalamic neurons monosynaptically receiving inhibitory input from the substantia nigra pars reticulata (SNr) and projecting to the frontal cortex in Japan...

The premotor cortex of macaque monkeys is currently subdivided into at least six different subareas on the basis of structural, hodological and physiological criteria. To determine the degree of divergence/convergence of thalamocortical projections to mesial [supplementary motor area (SMA)-proper and pre-SMA] and lateral (PMd-c, PMd-r, PMv-c and PMv-r) premotor (PM) subareas, quantitative analy...

The axonal projections of the juxtacapsular nucleus of the anterior division of the bed nuclei of the stria terminalis (BSTju) were examined with the Phaseolus vulgaris-leucoagglutinin (PHAL) method in the adult male rat. Our results indicate that the BSTju displays a relatively simple projection pattern. First, it densely innervates the medial central amygdalar nucleus and the subcommissural z...

23 The present report investigated the involvement of primate nigro24 thalamo-cortical projections in discrimination of visual signals with behavioral 25 meaning. We tested the extracellular unit activity of mediodorsal (MD) and 26 ventral anterior (VA) thalamic neurons monosynaptically receiving inhibitory 27 input from the substantia nigra pars reticulata (SNr) and projecting to the 28 fronta...

The quantitative 2-deoxy[14C]glucose method was used to determine local cerebral glucose utilization in unrestrained rats responding (lever-press) for rewarding electrical stimulation to area A10 (ventral tegmental area) and in similarly implanted inactive controls. Self-stimulation was associated with significant increases in metabolic activity, highly circumscribed in the ventral tegmental ar...

The medial prefrontal cortex has been associated with diverse functions including attentional processes, visceromotor activity, decision-making, goal-directed behavior, and working memory. The present report compares and contrasts projections from the infralimbic (IL) and prelimbic (PL) cortices in the rat by using the anterograde anatomical tracer, Phaseolus vulgaris-leucoagglutinin. With the ...
