Gray is seen because decreased lateral inhibition from neighboring cells decreases firing rate in the cell of interest.
Gray is seen in the white areas between black squares when looking at the Hermann Grid. This phenomenon illustrates the concept of lateral inhibition because
1. Gray is seen because decreased lateral inhibition from neighboring cells decreases firing rate in the cell of interest.
2. The color gray is actually present in the spaces between the squares.
3. Gray is seen because increased lateral inhibition decreases firing rate and therefore perceived brightness.
4. None of the above.
The White Illusion does not follow the standard lateral inhibition model. Why?
1. Instead of being processed along all edges, the gray blocks are grouped and, therefore, processed with either the black or white regions of the display.
2. There are two different shades of gray in the illusion, which causes you to see two different shades of gray.
3. You see the gray bars in the white rows as lighter because there is more black edge than white edge.
4. You see the gray bars in the black rows as darker because there is more black edge than white edge.
Where is inhibition transmitted in lateral inhibition?
1. sideways across the visual cortex
2. across the optic chiasm
3. in the edges of perceived objects
4. sideways across the retina
This one I think is 4 sideways across the retina
