Match the following brain regions with their roles in executive functions:

Premotor cortex (PMC) and Supplementary motor area (SMA) = Important for action initiation Anterior cingulate cortex (ACC) = Active for evaluating effort in a study involving squeezing for a reward Frontal polar cortex = Active for voluntarily switching between two tasks, especially when an active voluntary choice is made Dorsolateral prefrontal cortex (dLPFC) = Active for sequencing and planning tasks such as Tower of London task and self-ordered pointing task Signup and view all the answers

Match the following tasks with their descriptions:

Wisconsin Card-sorting task = Requires people to strategize, ignore irrelevant information, switch, learn from feedback, retrieve and monitor working memory Self-ordered pointing task = Involves picking different images every time and judging how recently they were seen Tower of London task = Involves moving balls on pegs to a goal position and planning the moves Go/No go task = Involves inhibiting a response on 'no-go' trials Signup and view all the answers

Match the following brain regions with their roles in cognitive control:

Anterior cingulate cortex (ACC) = Important for computing errors and identifying conflict Supplementary motor area (SMA) = Active when people must maintain the goal indicated by a cue and increases in activity when people must switch tasks Superior parietal lobule = More active for 4-move and 5-move trials in tasks like the Tower of London task Anterior insula cortex (AIC) = Active for error-related negativity and evaluating error for learning Signup and view all the answers
