Primate Thalamus: More Than Meets an Eye
A recent study shows conclusively that the koniocellular layers of the marmoset dorsal lateral geniculate nucleus have binocularly responsive neurons. This adds a new twist to the traditional view about binocular processing in the primate visual system and raises questions about the role of dorsal lateral geniculate nucleus in early binocular processing.
متن کاملFigure-ground modulation in awake primate thalamus.
Figure-ground discrimination refers to the perception of an object, the figure, against a nondescript background. Neural mechanisms of figure-ground detection have been associated with feedback interactions between higher centers and primary visual cortex and have been held to index the effect of global analysis on local feature encoding. Here, in recordings from visual thalamus of alert primat...
متن کاملCognitive signals in the primate motor thalamus predict saccade timing.
We often generate movements without any external event that immediately triggers them. How the brain decides the timing of self-initiated movements remains unclear. Previous studies suggest that the basal ganglia-thalamocortical pathways play this role, but the subcortical signals that determine movement timing have not been identified. The present study reports that a subset of thalamic neuron...
متن کاملThe primate thalamus is a key target for brain dopamine.
The thalamus relays information to the cerebral cortex from subcortical centers or other cortices; in addition, it projects to the striatum and amygdala. The thalamic relay function is subject to modulation, so the flow of information to the target regions may change depending on behavioral demands. Modulation of thalamic relay by dopamine is not currently acknowledged, perhaps because dopamine...
متن کاملNeural coding and perceptual detection in the primate somatosensory thalamus.
The contribution of the sensory thalamus to perception and decision making is not well understood. We addressed this problem by recording single neurons in the ventral posterior lateral (VPL) nucleus of the somatosensory thalamus while trained monkeys judged the presence or absence of a vibrotactile stimulus of variable amplitude applied to the skin of a fingertip. We found that neurons in the ...
