Attention

Question 1

What are the types of cell coding for attention?

Answer 1

Enhancing/supressing response, sharpening to specific types of stimuli, tuning other cells

Question 2

What is the sensory recruitment theory of visual working memory?

Answer 2

If you do not verbalize a cue, the encoding and retention will be in the visual areas. It proposes that the same cortical regions that contribute to online perceptual processing of a stimulus are recruited to maintain that information in WM

Question 3

What are theories of neglect?

Answer 3

Inhibition imbalance, the intact hemisphere is hyperactive.
The contralesional stimulus does not win from the ipsilesional stimulus. Disengagement of attention from the ipsilesional side is difficult.

Question 4

What does prism adaptation (not) do?

Answer 4

It alters motor behaviour by the dorsal stream, but not the ventral perception stream.

Question 5

What does the premotor theory of attention entail?

Answer 5

The same neurons that program attention program saccades as well

Question 6

Dorsal stream attention

Answer 6

Control over attention, near space, motor response

Question 7

Ventral stream attention

Answer 7

far space, orientation, identification
