How do we see Flashcards
what 3 stages do we go through in order to see?
reception
transduction
perception
what is reception
info detection
what is transduction
converted to electrical signals
what is perception
influenced by what we see and what we know
what are the 4 stages of eye movements
light enters eye and is focused on fovea
we move our eyes to view our environment
when our eye stops, fixation occurs
eye movements are saccades where no visual info is extracted
what are the 4 stages in which light moves from our eye to our brain
photorecpetor in eye
other retinal neurons
thalamus
occipitial lobe
so how do we actually see
light passes through pupil and lens where it is focused on to the retina. The retina turns it into an electrical impulse where it travels to the brain via the optic nerve
