The presently dominant model suggests that color and orientation are separately extracted in the primate primary visual cortex. These characteristics are thought to be represented by neurons located in different cortical columns that project separately to higher visual areas for further processing. Working...
Acquisition of new skills has the potential to disturb existing network function. To directly assess whether previously acquired cortical function is altered during learning, mice were trained in an abstract task in which selected activity patterns were
thalamus. The superior colliculus could potentially also influence the input to the primary visual cortex through its projection to the shell of the dLGN12. This tectogeniculate projection is anatomically present in all studied mammals13, but there has been no evidence that it has a functional eff...
produce a simulated neural image that shares many of the properties of the simple cell representation in primary visual cortex. Models such as this have enormous value in that they give vision scientists a sort of testbed that can be used to investigate other aspects of visual function, e.g....

A cubic millimeter of primary visual cortex contains about 100,000 neurons that are heavily interconnected by intrinsic and extrinsic afferents. The effort of many neuroanatomists over the past has revealed the general outline of these connections; however, their function remains a mystery. Recently,...
