distribution of photoreceptors Flashcards
1
Q
different resolutions for…
A
the rods and the cone cells, depending on the environment
2
Q
resolution
A
how clearly two objects are seperate
3
Q
our lowest resolution
A
in our peripheral vision, edges of the retina
4
Q
why does the peripheral vision have the lowest resolution?
A
this part of the retina contains mostly rod cells
5
Q
why do rod cells produce poorer resolution than cone cells?
A
because multiple rod cells connect to a single bipolar cell, if light hits one rod cell, it causes an action potential in the bipolar cell which is sent to the brain
