visual cortex Flashcards
the visual cortex is also known as _____ cortex
striate
why is V1 easily notifiable?
because of layer 4b (aka stria of Gennari)
layer 4 is the ____ layer
input layer
which layers of V1 are most densely packed?
4c and 6
stellate interneurons
spiny _____ergic and non spiny _____ergic
spiny -> glutamatergic
non spiny -> GABAergic
medial tract of orientation columns
optimum orientations change ____
slightly
lateral tract of orientation columns
optimum orientations change ____
markedly
which is thinner: ocular dominance columns or orientation columns
orientation
cytochrome oxiddase staining in V1 AND V2 showed
blobs in v1
striped in v2
orientation pinwheels fall on ____

on/off domains in visual cortex
ON and OFF afferents are also segregated nearly orthogonal (at right angles) to the ocular dominance columns in cat visual cortex
