Cells of geniculocortical pathway

Question 1

ganglion cells vs other neurons in the retina

Answer 1

ganglion cells: are capable of exporting visual info from the retina

other neurons: filter, modulate, and enhance the relative change in visual landscape

Question 2

M ganglion cells

Answer 2

vertical connection to rods, carries information regarding motion

Question 3

P ganglion cells

Answer 3

vertical connection to cones, carries information regarding color

Question 4

where do M ganglion cells project to in the LGN and retina

Answer 4

LGN: project to the magnocellular layers

magnocellular cells are evenly distributed throughout retina

Question 5

where do P ganglion cells project to in the LGN

Answer 5

LGN: project to parvocellular layers

parvocellular cells are restricted to central retina (macula)

Question 6

what do M cells project to in cerebral cortex

Answer 6

layer 4C alpha

Question 7

what do P cells project to in cerebral cortex

Answer 7

layer 4C beta and layer 4A
