,Learning goals
1/ what neurons or cells are responsible for the visual cortex?
2/ how does the position of a line stimulate the impulse?
3/ why do impulses decrease as the orientation differs from 0?
4/which areas are responsible for the detection of motion and
color?
5/ what happens when there is damage?
