Question 1

Why is the primary visual cortex often referred to as the striate cortex?

Answer 1

There are signals that carry information form the LGN to the V1. Because axons carrying signals from LGN are myelinated while axons in the primary visual cortex are not, there are lines that are visible to the naked eye. They often form striates (stripes)

complex: respond to a line of preferred orientation at ANY location in a receptive field

Question 3

Answer 3

complex cells

Question 4
