Prefrontal cortex

Question 1

Order the following parts of the frontal lobes from most posterior to most anterior/curving round to the bottom of the frontal lobes: lateral PFC, ventromedial PFC, primary motor area, premotor area

Answer 1

Primary motor area, premotor area, lateral PFC & ventromedial PFC

Question 2

On one of the brain diagrams lateral PFC does not appear because…

Answer 2

lateral PFC resides on the surface of each side of the brain, not as a bulky chunk residing on the left most surface of the RH & vv which is VMPFC

Question 3

Define executive control

Answer 3

The ability to select actions or thoughts in relation to internal goals

Question 4

Duncan’s idea of a general “multiple demand network” which includes dlPFC, ACC & parietal cortex is supported by ___ evidence, whereas…

Answer 4

Correlational (these areas are activated by multiple demands). Lesion studies (from which causality can be inferred) suggest that dlPFC, ACC & parietal cortex perform specific and differentiated roles

Question 5

Badre (2006) found that ___ conflict activated PMc, whereas ___ conflict activated posterior dlPFC & ___ activated anterior dlPFC

Answer 5

Response, feature, dimension

Question 6

Pps with lesions of the most anterior parts of PFC are impaired at ___ conflict tasks but not at ___ conflict tasks

Answer 6

Dimension, feature

Question 7

According to Petrides’ (1985) work on macaque lesions, caudal dlPFC processes rules which guide…

Answer 7
