A new code for contrast in the primate visual pathway.
We characterize a hitherto undocumented type of neuron present in the regions bordering the principal layers of the macaque lateral geniculate nucleus. Neurons of this type were distinguished by a high and unusually regular maintained discharge that was suppressed by spatiotemporal modulation of luminance or chromaticity within the receptive field. The response to any effective stimulus was a r...

متن کاملOptogenetics Advances in Primate Visual Pathway
In this issue of Neuron, Klein et al. (2016) used cell-type-specific optogenetics and electrical microstimulation to characterize the koniocellular geniculocortical projections in nonhuman primates. Their work offers a powerful platform for refining our understanding of the mechanisms of visual information processing in the lateral geniculate nucleus and primary visual cortex.

متن کاملMultiple adaptable mechanisms early in the primate visual pathway.
We describe experiments that isolate and characterize multiple adaptable mechanisms that influence responses of orientation-selective neurons in primary visual cortex (V1) of anesthetized macaque (Macaca fascicularis). The results suggest that three adaptable stages of machinery shape neural responses in V1: a broadly tuned early stage and a spatio-temporally tuned later stage, both of which pr...
