Q

Slide 3: According to localization models of cortical function, a _______lesion should cause a ______dysfunction.

discrete; discrete

5
Q

Slide 4: Wernicke’s and Broca’s areas are part of the _______ network within the cortex.Language, face and object, executive, or memory and emotion

A

Language

6
Q

Slide 5: Which of the cortical network centers are used and involved with language?Hearing, seeing, speaking or thinking about words?

A

All of these areas are used for language

7
Q

Slide 7: Match model of cortical function with the theory:(1) Associative processing(2) Holistic processing(3) Localized function(A) Lesion ==> loose that function(B) Lesion ==> don’t lose function entirely; lose it partially because other parts of the brain network help pick-up slack and retain that function(C) Lesion ==> can significantly impair function but it depends particularly on where the lesion occurred

A

(1) = (C)(2) = (B)(3) = (A)
