The visual system II

Question 1

What is the two streams hypothesis? What is wrong with this hypothesis?

Answer 1

Information from the visual cortex is sent to the parietal cortex via the dorsal pathway (important for “where” tasks) and to the temporal cortex via the ventral pathway (for “what” tasks)

Lots of interconnections between pathways, and some “what” tasks take the dorsal pathway/some “where” tasks take the ventral pathway

Question 2

What percentage of the anatomical connectivity of the human visual system is known?

Answer 2

0%

Question 3

The size of Extrastriate receptive fields is ____ than RFs in V1 RFs

Answer 3

Larger

Question 4

V1 RFs arrange in ____ and V2 RFs arrange in ___

Answer 4

Blobs

Bands

Question 5

What are similarities and differences between Visual areas?

Answer 5

Areas maintain retinotopic organization
RFs increase from V1 to higher level areas
RF structure becomes more complex and unpredictable

Question 6

True/False? Prosopagnosia is related to FFA injury

Answer 6

False?
