Wähle eine der folgenden:

  • Monocular

  • Binocular

  • Monocle

  • Trinoculor

  • Stereoscopic vision

Erklärung

Frage 4 von 12

1

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

Wähle eine der folgenden:

  • Hypercolumn

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

Erklärung

Frage 5 von 12

1

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

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 6 von 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.

Frage 7 von 12

1

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

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 8 von 12

1

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

Wähle eine der folgenden:

  • 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.

Erklärung

  • Fat stripes

  • Thin stripes

  • Bright stripes

  • Dull stripes

  • Degrees

  • Light reflection

  • Orientation

Erklärung
