task 2 - cognition

Question 1

lateral PFC

Answer 1

sustained activation related to the “cognitive control” of all the elements that are required during task execution in line with Miller’s model
flexibility to shift between rules, biased/top-down control
IPS
IFJ

Question 2

intraparietal sulcus

Answer 2

selects objects via their location

Question 3

inferior frontal junction

Answer 3

biasing perception
switching from bottom-up (ventral attention system) to top-down control (dorsal attention system) by synchronizing with areas’ frequencies

Question 4

SPL (superior parietal lobule)

Answer 4

encodes detailed features of objects selected by IPS

Question 5

(pre-)SMA

Answer 5

depends on LPFC’s translation of the IPS and FEF representations into a motor goal, so that it can take that motor goal to select appropriate actions

Question 6

task rules

Answer 6

related to what processing

Question 7

bias signals

Answer 7

PFC sends excitatory bias signals to the object of focus to inhibit all other objects by means of mutual inhibition.
all the neurons around the excitatory bias neuron are inhibited by inhibitory signals.

Question 8

attention

Answer 8

from observation of environment –> to object selection
switching between tasks
lateral intraparietal area
