Cortical blindness
When the primary visual cortex is destroyed, those affected are effectively blind, even though their eyes are undamaged. However, they are often unconsciously able to grasp and catch objects and even name them when asked to guess. This effect is known as blind sight.

Hypercomplex cell
A nerve cell in the primary visual cortex that responds most strongly to short, moving lines or corners in its receptive field. It exhibits end-stopping, meaning that the response strength decreases when the stimulus becomes longer than optimal. Hypercomplex cells are sensitive to the orientation and direction of movement of the stimulus and contribute to the perception of edges, corners, and curves.
