Visual Flashcards
What is the sensitivity of rods?
High
Do rods have a lot of photopigment or a little?
A lot, to capture more light
Describe amplification for the rods.
High, single photon detection
Describe the temporal resolution, response, and integration time of rods.
Low temp resolution, slow response, long integration time
What type of light are rods sensitive to? direct or scattered
scattered
Describe saturation of rods
saturate in daylight
Describe acuity and convergence of rods
low
How many types of photopigment are in rods
1
Magnocellular layers
Large cell bodies and receptive fields, transient response to continuous light (rapidly adapting). Respond best to movement and large objects
Parvocellular layers
small cell bodies and receptive fields, with 1:1 relation to cones. respond best to color and fine detail
What layer in the primary visual cortex is greatly expanded?
Layer 4
