1
Q
What cells perform lateral inhibition in retina?
A
Horizontal and amacrine cells
2
Q
Where is the lateral geniculate nucleus found?
A
Thalamus
3
Q
One the visual signals have passed from the ganglion cells they go to one of the following cells, what do each of them provide information about:
- P cells (80%)
- M cells (10%)
- non-P and non-M cells
A
P cells - colour and shape
M cells - movement
Non-M and non-P cells - colour
4
Q
Layer 4C of the primary visual cortex receives signals from the lateral geniculate nucleus.
Layer 4C-alpha
Layer 4C-beta
Receive signals from what kind of retinal output?
A
Alpha - M cells (alpha = movement)
Beta - P cells
