Resource summary

Question 1

Question
Considering the selectivity for eye of origin. Which eye(s) would a cell in the ocular dominance range of 4 comes from?
Answer
  • Both eyes equally
  • Mostly left eye
  • Mostly right eye
  • Right eye only
  • Left eye only

Question 2

Question
The ocular dominances of 1 & 7 are...
Answer
  • Monocular
  • Binocular
  • Monocle
  • Trinoculor
  • Stereoscopic vision

Question 3

Question
The range of orientations a particular cell fires to is called its..
Answer
  • Bandwidth
  • Preferred Orientation
  • Selective Orientation
  • Orientation selectivity
  • Broadband

Question 4

Question
Input from both eyes and all 180 degrees of orientation selectivity in a section of V1 is called a...
Answer
  • Hypercolumn
  • 360 degrees column (2 eyes at 180 degrees each)
  • Complex column
  • Column of ocular dominance

Question 5

Question
Complex cells are less stimulus specific than simple cells and hypercomplex cells are even less specific than complex cells.
Answer
  • True
  • False

Question 6

Question
Drop the type of cell to its description These cells respond to a oriented stimulus in a specific location within their receptive fields. [blank_start]Simple Cells[blank_end] These cells respond most strongly to oriented lines of specific lengths but respond less to lines longer than that length. [blank_start]Hypercomplex Cells[blank_end] These cells will respond to orientations of any length anywhere within their receptive field. [blank_start]Complex Cells[blank_end]
Answer
  • Simple Cells
  • Hypercomplex Cells
  • Complex Cells

Question 7

Question
Some cells in the V2 may help us to see subthreshold edges by combining signals from hypercomplex cells.
Answer
  • True
  • False

Question 8

Question
Which of the following is an explanation for the tilt aftereffect?
Answer
  • After adaptation to one orientation, that particular cell will temporarily fire less to its usual stimuli, therefore that cell will not contribute as much as it usually would when a new stimulus is presented.
  • Adaptations fatigue cells
  • Magic
  • Prolonged exposure to tilted bars makes subsequently seen vertical lines appear tilted in the opposite direction.
  • This occurs as a result of the way the configurations of simple and complex cells are organised.

Question 9

Question
Which of the following would have a low spatial frequency?
Answer
  • Fat stripes
  • Thin stripes
  • Bright stripes
  • Dull stripes

Question 10

Question
Considering the sinusoidal waves for spatial frequency, what part of the wave relates to contrast levels?
Answer
  • Amplitude
  • Frequency
  • Phase
  • Fourier Analysation
  • Degrees
  • Light reflection
  • Orientation

Question 11

Question
[blank_start]High[blank_end] spatial frequencies carry finer details. [blank_start]Low[blank_end] spatial frequencies carry course information.
Answer
  • High
  • Low
  • Low
  • High

Question 12

Question
Humans are better at seeing...
Answer
  • Mid range spatial frequencies.
  • Higher spatial frequencies.
  • Lower spatial frequencies.
  • All spatial frequencies equally.
