PSY346H5 Lecture Notes - Lecture 2: Tegmentum, Brainstem, Medial Geniculate Nucleus
Document Summary
Neuroanatomy and neurochemistry: understanding the biological basis of beh, structural familiarity, neurotransmitter pathways that connect areas of the brain together. Frontal + parietal lobe --> central sulcus: delineates the frontal lobe + parietal lobe. Some really special of cells: towards ventral area, mirror neurons. See/incoming info + decide action based on that: top-down. Leap of logic rather than a direct measurement: want to take look at difference in task of one you are interested in vs normal condition --> subtraction method. Similar functions but there is ex towards bias of one towards the other: how know involved in motor inhibition + decision uncertainty, cognitive tests: go/no-go visual reaction time. Shows difference between bottom-up + top-down processing: go + no-go tasks. Shows "contrast" of activity between go and no-go tasks: more activity on "no-go" will appear as brighter red, compare left and right hemisphere activity, orbital frontal cortex (ofc)
