-
Monocular
-
Binocular
-
Monocle
-
Trinoculor
-
Stereoscopic vision

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

Frage 5
Frage
Complex cells are less stimulus specific than simple cells and hypercomplex cells are even less specific than complex cells.
Antworten
- True
- False
Frage 6
Frage
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]
Antworten
-
Simple Cells
-
Hypercomplex Cells
-
Complex Cells
Frage 7
Frage
Some cells in the V2 may help us to see subthreshold edges by combining signals from hypercomplex cells.
Antworten
- True
- False
Frage 8
Frage
Which of the following is an explanation for the tilt aftereffect?
Antworten
-
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.
Frage 9
Frage

Antworten
-
Fat stripes
-
Thin stripes
-
Bright stripes
-
Dull stripes

-
Light reflection
-
Orientation
