Document Summary
The transparent window on the outer part of the eye which allows light into the eyeball is called the . The first cells are the ganglion cells have to be close to the pigment epithelium because this provides nutrients to the photoreceptors. Correct rejections means seeing no signal when there isn"t any signal you have to look for the graph where there are no responses to the left. The graded potential are not all or none events like when neurons fire, instead they reflect the potential of the membrane. If the bipolar cell is an on-bipolar cell (on means that it is activated by light), it is going to reverse the sign of the photoreceptor. Graded potentials= only event in the cns which is not all or none, its graded. Receptive fields have a center surround organization; they can have an on center and. Off surround, or an off center and on surround.
