Simultaneous recordings from all layers in the primary visual cortex (V1) of the behaving mouse revealed functionally defined layers in V1. The depth of maximum spike power and sink-source distributions of LFPs
The primary visual cortex has a laminar structure common to the neocortex, with six defined layers (see Fig. 9.2). Input from the LGN is received in layer 4, where it is further segregated by the type of LGN cell it receives (magno/parvocellular/koniocellular). The deeper layers (5 and...
In this study, we aim to understand how the primary visual cortex (V1) processes surface luminance information across its different layers. We report that edge-driven responses are stronger than surface-driven responses in V1 input layers, but luminance information is coded more accurately by ...
Neuronal activity in early visual cortex depends on attention shifts but the contribution to working memory has remained unclear. Here, we examine neuronal activity in the different layers of the primary visual cortex (V1) in an attention-demanding and a working memory task. A current-source dens...
Three basic receptive field types were found: (1) Cells with oriented receptive fields, many of which could be classified as simple or complex, were found in all layers of the cortex, but occurred with greater frequency in layers II and III and less commonly in Layer IV. (2) Cells with...
(Supplementary Fig.12b). We did not observe significant differences in the NCS response latencies in different layers (Supplementary Fig.12c). Therefore, V1 units that respond to illusory brightness have a bias toward the superficial layers, which receive top-down cortico-cortical feedback, and ...
A biological blueprint for the axons of superficial layer pyramidal cells in cat primary visual cortexdoi:10.1007/s00429-017-1410-6Pyramidal cells in the superficial layers of neocortex of higher mammals form a lateral network of axon clusters known as the 'daisy' network. The role of these ...

Serotonin axons, present in all cortical layers, form two especially prominent, dense bands of arborizing fibers; one extending from midlayer III through IVC-alpha and the other from VA through VI. NE axons within cynomolgus visual cortex are markedly less dense than 5-HT axons, and laminar ...
