NSCI 225 Exam 2 | UPDATED Questions with 100% Verified Answers
Question:
retinotopic mapping
Answer:
Spatial organization of the LGN and primary visual cortex in which adjacent cells in the
brain process adjacent locations on the retina.
Question:
cortical magnification
Answer:
the amount of cortical area devoted to a specific region in the visual field
Question:
Hypercolumn Function
Answer:
Each hypercolumn analyzes information from one small region of retina; One
hypercolumn contains all measurements for one local area
Question:
Hypercolumn Structure
Answer:
Made up of ocular dominance slabs for each eye and those made up of orientation
columns; Contains cells that measure all characteristics of the image falling on a small
region of the retina
Question:
location column
Answer:
column in the visual cortex that contains neurons with overlapping receptive fields on the
retina
Question:
orientation column
, Answer:
A column in the visual cortex that contains neurons with the same orientation preference.
Question:
ocular dominance column
Answer:
functional column in the visual cortex maximally responsive to information coming from
one eye
Question:
gratings
Answer:
a series of light and dark bars; a tool for finding feature detectors in the human visual
system
Question:
selective adaptation
Answer:
neurons adapt after extended exposure to a stimulus; firing rate decreases and neuron
fires less when stimulus is repeated
Question:
when does grating adaptation occur?
Answer:
only when the lines are the same orientation
Question:
interocular transfer
Answer:
The transfer of an effect (such as adaptation) from one eye to the other
Question:
Where are binocular neurons first encountered?
, Answer:
the cortex
Question:
what happens if we never have exposure to a certain
orientation?
Answer:
can't perceive it
Question:
where does more complex visual processing take place?
Answer:
extrastriate cortex
Question:
what is the extrastriate cortex made up of?
Answer:
many small areas such as V2, V3, etc.
Question:
IT Cortex Neurons
Answer:
neurons get even more specific about what they fire to
Question:
Modularity
Answer:
the notion that certain cognitive processes (or regions of the brain) are restricted in the
type of information they process
Question:
fusiform face area
Answer:
