Topic 6: Attention and Consciousness Flashcards
Describe the brain’s default mode network.
The brain's default network is a collection of brain areas that are particularly active during rest, specifically: Medial prefrontal cortex Posterior cingulate cortex Posterior parietal cortex Hippocampus Lateral temporal cortex
Recite: Attention is the ability to focus on one aspect of sensory input
Attention is the ability to focus on one aspect of sensory input
Which of the following is NOT correct re resting state activity:
A. Some regions are fairly quiet
B. Some regions are surprisingly active
C. Patterns in brain activity changes are unique to individuals
D. Brain areas active in resting state are the default mode network
C. Patterns in brain activity changes are unique to individuals
Correction:
•Patterns in brain activity changes consistent across human
subjects
Exogeneous attention:
A. Is bottom-up attention
B. Is top-down attention
C. Is mediated by the FEF, V1, V2 and V4
D. Drives attention for deliberate, voluntary and goal-directed behaviour
A. Is bottom-up attention

The sentinel hypothesis posits that:
A. The default mode network functions to support thinking and remembering, like daydreaming
B. The default mode network function is unimportant and misleading as sentients are constantly aware
C. The default mode network functions to broadly monitoring the environment so that bottom-up attention signals can interrupt rest
D. The default mode network functions to serve top-down processing by directed attention to goal-driven behaviours
C. The default mode network functions to broadly monitoring the environment so that bottom-up attention signals can interrupt rest
