Q

temporal memory

A

information collected from the dorsal and ventral streams

21
Q

working memory

A

what are you thinking about in the here and the now

22
Q

external cuews

A

23
Q

context cues

A
  • Social interactions (orbitofrontal PFC)
24

A

loss of dopamine cells in the substantia nigra thaat project to prefrontal cortex

37

Frontal lobe lesions produced alterations in voluntary eye gaze

48
Q

prolonged stress is correlated with functionally significant changes in …

A

the structure of neurons in the PFC that affect temporal memory and goal-directed behaviors
