Brodmann's Areas

Question 1

Precentral Gyrus - lobe, brodmann’s, function

Answer 1

frontal, primary motor area (4), isolated movement

primary motor - contains giant Betz cells in layer 5

Question 2

Premotor area - lobe, brodmann’s, function

Answer 2

frontal, lateral area 6, motor planning/Cb

stimulus evokes complex multisegmental movement

Question 3

Supplemental motor area - lobe, brodmann’s, function

Answer 3

frontal, medial area 6, motor planning/BG

stimulus evokes complex multisegmental movement

Question 4

FEF - lobe, brodmann’s, function

Answer 4

frontal, area 8, contra saccades

Question 5

Prefrontal cortex - lobe, brodmann’s, function

Answer 5

frontal, executive function

relation to emotions, personality, intellect, executive function
lobotomies - orbital gyri more related to emotions, lateral gyri to intellect

Question 6

Left inferior frontal gyrus - lobe, brodmann’s, function

Answer 6

frontal, broca’s (44,45), language expression

broca’s - in dominant hemi, rostral to primary motor area, non-fluent aphasia

Question 7

Postcentral gyrus - lobe, brodmann’s, function

Answer 7

parietal, primary sensory area (1,2,3), unimodal simple sensation

Question 8

Superior pariental lobule - lobe, brodmann’s, function

Answer 8

parietal, unimodal sensory association cortex (5,7), unimodal complex sensation

Question 9

Inferior pariental lobule - lobe, brodmann’s, function

Answer 9

heteromodal sensory association cortex (39,40), higher order perception

spatial relations, recognition of objects, ability to make whole out of parts, attention to contra space (“where” pathway)

temporal-occipital area - recognition of faces (“what” pathway)

Question 10

Area around calcarine fissure - lobe, brodmann’s, function

Answer 10

occipital, primary visual cortex (17), simple vision

mostly monocular, organized in ocular dominance columns

Question 11

Other medial and all lateral occipital lobe - lobe, brodmann’s, function

Answer 11

occipital, secondary visual cortex (18,19), unimodal complex vision, movement, color

concentric to area 17 (movement, color)
other visual association (heteromodal) cortex in temporal and parietal lobes

Question 12

Superior temporal gyrus - lobe, brodmann’s, function

Answer 12

temporal, primary and secondary auditory areas (41,42), hearing

primary - 41, transverse temporal gyrus (input from med gen)
secondary - 42, receives input from 41 and med gen (i.e. unimodal association cortex)

both ears represented on both sides so uni stroke produces no appreciable hearing loss

Question 13

Left superior temporal gyrus - lobe, brodmann’s, function

Answer 13

temporal, wernicke’s (22), language comprehension

wernicke’s - post part, in dominant hemi, fluent aphasia

Question 14

Parahippocampal gyrus - lobe, brodmann’s, function

Answer 14

temporal, amygdala, visceral control

amygdala - visceral association with emotion

Question 15

Hippocampus

Answer 15

declarative memory

Question 16

Cingulate Gyrus

Answer 16

23,24, emotions
