Week 6 - Spatial Vision

Week 6 - Spatial Vision

Question 1 of 12

1

Considering the selectivity for eye of origin. Which eye(s) would a cell in the ocular dominance range of 4 comes from?

Select one of the following:

  • Both eyes equally

  • Mostly left eye

  • Mostly right eye

  • Right eye only

  • Left eye only

Explanation

Question 2 of 12

1

The ocular dominances of 1 & 7 are...

Select one of the following:

  • Monocular

  • Binocular

  • Monocle

  • Trinoculor

  • Stereoscopic vision

Explanation

Question 3 of 12

1

The range of orientations a particular cell fires to is called its..

Select one of the following:

  • Bandwidth

  • Preferred Orientation

  • Selective Orientation

  • Orientation selectivity

  • Broadband

Explanation

Question 4 of 12

1

Input from both eyes and all 180 degrees of orientation selectivity in a section of V1 is called a...

Select one of the following:

  • Hypercolumn

  • 360 degrees column (2 eyes at 180 degrees each)

  • Complex column

  • Column of ocular dominance

Explanation

Question 5 of 12

1

Complex cells are less stimulus specific than simple cells and hypercomplex cells are even less specific than complex cells.

Select one of the following:

  • True
  • False

Explanation

Question 6 of 12

1

Drop the type of cell to its description

These cells respond to a oriented stimulus in a specific location within their receptive fields.

These cells respond most strongly to oriented lines of specific lengths but respond less to lines longer than that length.

These cells will respond to orientations of any length anywhere within their receptive field.

    Simple Cells
    Hypercomplex Cells
    Complex Cells

Explanation

Question 7 of 12

1

Some cells in the V2 may help us to see subthreshold edges by combining signals from hypercomplex cells.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 12

1

Which of the following is an explanation for the tilt aftereffect?

Select one of the following:

  • 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.

Explanation

Question 9 of 12

1

Which of the following would have a low spatial frequency?

Select one of the following:

  • Fat stripes

  • Thin stripes

  • Bright stripes

  • Dull stripes

Explanation

Question 10 of 12

1

Considering the sinusoidal waves for spatial frequency, what part of the wave relates to contrast levels?

Select one of the following:

  • Amplitude

  • Frequency

  • Phase

  • Fourier Analysation

  • Degrees

  • Light reflection

  • Orientation

Explanation

Question 11 of 12

1

Select from the dropdown lists to complete the text.

( High, Low ) spatial frequencies carry finer details.

( Low, High ) spatial frequencies carry course information.

Explanation

Question 12 of 12

1

  • Mid range spatial frequencies.

  • Higher spatial frequencies.

  • Lower spatial frequencies.

  • All spatial frequencies equally.
