Abstraction of Cortical Neurons, Responsive to both the Polarity and Orientation of Edges, and not J

Caption

A key feature of visual scenes is the polarity of local changes in luminance. Polarity signals are segregated in the activity of different populations of neurons as early as the retina and relayed into cortex. However, the fate of these polarity signals within the activity of cortex has remained uncertain. In this paper, we show that information about edge polarity and orientation are jointly encoded and preserved within the population activity of superficial layers of visual cortex.
