Medial PFC

Question 1

When Chris referred to the medial PFC in the lecture he was referring mostly to clusters __ & __ on the cingulate cortex connectivity map i.e. ___ ___ cingulate cortex (CC). What is this map?

Answer 1

4 & 5. Dorsal anterior. A map which divides cingulate cortex up into areas which connect to similar places.

Question 2

Where is the cingulate cortex in relation to the corpus callosum and the dorsomedial PFC?

Answer 2

ACC is just above the corpus callosum, contains an anterior & posterior region & is just below the dorsomedial PFC

Question 3

Brodmann’s areas 6, 8 & 9 represent the dorsomedial PFC. Brodman’s areas __ and __ represent ACC

Answer 3

24, 32

Question 4

Although mPFC has a similar ___ in humans & macaques, this does not imply that the region has equivalent functions in both species

Answer 4

Morphology

Question 5

Give the names of 2 tasks for which we tend to be aware when we have made an error

Answer 5

The Stroop task (name the ink colour rather than the word) & Eriksen Flanker task (respond to the central arrow rather than the surrounding arrows)

Question 6

Name 3 other lab tasks which tend to (or can be designed to) give rise to errors

Answer 6

1) The Simon task (we are slower to make a leftwards response to a stimulus presented in the right VF). 2) Go/no go task (it’s difficult to not respond to the rarely presented letter e.g. X). 3) Stop-signal task (it’s difficult to respond to a rarely presented stop sign presented a while after the usual go cue)

Question 7

The Simon task, go/no go task & stop-signal task each measure 1), 2) & 3) respectively - what are 1), 2) & 3)?

Answer 7

1) Interference inhibition, 2) Action withholding & 3) Action cancellation

Question 8

The ERN is calculated by subtracting the ERP during an ___ trial from the ERP during a ___ trial. The X axis ascends by ___ ms each time and the Ne occurs at 0ms i.e. when the ___ is made

Answer 8

Incorrect subtracted from correct. 200ms. Response
