Lecture 11, 12 (handouts) Flashcards
what is the most common cell type in V1? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
D) Complex cells
Which of the following are orientation selective? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
C and D: simple and complex cells
Which of the following are edge detectors? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
C) simple cells
which of the following have antagonistic (on/off) receptive fields? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
A,B,C: ganglion, LGN, and simple cells
Which of the following can respond directly to a light stimulus? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
A) ganlion cells, because they have melanopsin
Which of the following are located in the cerebrum (brain)? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
C and D: simple and Complex only. ganglion cells are in the retina and LGN cells are in the thalamus between the cerebrum and midbrain
Which of the following are direction detectors? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
all 4 of them
Which of the following have center surround receptive fields? A) Ganglion cells B) LGN C) Simple cells D) Complex cells
A and B: ganglion and LGN
Are complex cells excitatory or inhibitory?
neither, this is why they are not considered antagonistic (on/off)
magnocellular pathways travel from retina to LGN then on to what part of the visual cortex?
4B and 4CA and are responsible for movement (magno=movement)
parvocellular pathways travel from retina to LGN then on to what part of the visual cortex?
4CB and blobs and are responsible for shape and color (parvo=particulars)
koniocellular pathways travel from retina to LGN then on to what part of the visual cortex?
blobs and are responsible for color (konio, like cone, color)
