Layer-specific input to distinct cell types in layer 6 of monkey primary visual cortex.
Layer 6 of monkey V1 contains a physiologically and anatomically diverse population of excitatory pyramidal neurons. Distinctive arborization patterns of axons and dendrites within the functionally specialized cortical layers define eight types of layer 6 pyramidal neurons and suggest unique information processing roles for each cell type. To address how input sources contribute to cellular fun...
متن کامل1 Asymmetric Temporal Integration of 2 Layer 4 and Layer 2 / 3 Inputs in Visual Cortex
21 Neocortical neurons in vivo receive concurrent synaptic inputs from multiple sources, 22 including feedforward, horizontal, and feedback pathways. Layer 2/3 of the visual cortex 23 receives feedforward input from layer 4 and horizontal input from layer 2/3. Firing of the 24 pyramidal neurons, which carries the output to higher cortical areas, depends critically 25 on the interaction of these...

Neocortical neurons in vivo receive concurrent synaptic inputs from multiple sources, including feedforward, horizontal, and feedback pathways. Layer 2/3 of the visual cortex receives feedforward input from layer 4 and horizontal input from layer 2/3. Firing of the pyramidal neurons, which carries the output to higher cortical areas, depends critically on the interaction of these pathways. Here...
متن کاملRole of layer 6 of V2 visual cortex in object-recognition memory.
Cellular responses in the V2 secondary visual cortex to simple as well as complex visual stimuli have been well studied. However, the role of area V2 in visual memory remains unexplored. We found that layer 6 neurons of V2 are crucial for the processing of object-recognition memory (ORM). Using the protein regulator of G protein signaling-14 (RGS-14) as a tool, we found that the expression of t...
متن کاملLocal connections to specific types of layer 6 neurons in the rat visual cortex.
Because layer 6 of the cerebral cortex receives direct thalamic input and provides projections back to the thalamus, it is in a unique position to influence thalamocortical interactions. Different types of layer 6 pyramidal neurons provide output to different thalamic nuclei, and it is therefore of interest to understand the sources of functional input to these neurons. We studied the morpholog...
