lecture 19 Flashcards
attention
3 networks of attention
alerting, orienting, executive
alerting network
arousal and sensitivity to stimuli, attentional capture
locations associated with alerting
locus coeruleus, frontal and parietal cortex, stimuli alerts the forebrain
neurotransmittier for alerting network
norepinephrine
orienting network
moving attention from place to place, motor control, prioritizes one sense over another or location in space
orienting neurotransmitter
acetylcholine
locations associated with orienting network
superior parietal, TPJ, frontal eye fields, superior colliculus, pulvinar
dorsal orienting network
right lateralized, top-down directing of attention towards a specific object
goal-oriented selective attention
ventral orienting network
syncs current activity with bottom-up incoming sensory info, reorienting
executive network
determine what you want to pay attention to, self control and regulation, task management
locations associated with executive network
anterior cingulate and insula, basal ganglia
executive network neurotransmitter
dopamine
exeuctive top-down processing networks (2)
dorsolateral-prefrontal-cortex-parietal network (dlPFCP)
and
anterior cingulate/medial-frontal-anterior insula network (aCI)
dlPFCP
active at beginning of task, starter, moment-to-moment task
aCI
remains active throughout task, finisher, task set maintenance in continuing and finishing a task
