Question 1

Saccades

Answer 1

To get a clear picture, we’re constantly redirecting our gaze to different directions (about 3/4 per s)

Question 2

Lateral geniculate nucleus (LGN)

Answer 2

Signal goes to LGN in the thalamus. This consists of 6 layers, which each respond to left or right eye. So still separate here.

Question 3

Magnocellular system

Answer 3

two bottom layers, magnocellular ganglion cells (big neurons), predominantly parafoveally

Question 4

Parvocellular system

Answer 4

4 layers, smaller neurons which receive more projections from the fovea.

Question 5

Optic radiation

Answer 5

Axons from the LGN project signal to the primary visual cortex
