CSDS 172 - Brodmann Area

1, 2, 3

primary sensory strip

receives sensory feedback from joints and tendons

4

precentral gyrus or primary motor area

responsible for voluntary control of skeletal muscles on the contralateral side

5, 7

sensory association cortex

detailed discrimination and analysis than the primary sensory areas

involved in sensing how hot or cold something is

6

premotor or supplemental motor area

programs and regulates complex and skilled motor movements (not speech)

8

anterior of the premotor cortex. It facilitates eye movements and is involved in visual reflexes as well as pupil dilation and constriction.

9, 10, 11, 12

anterior to area 8

involved in cognitive processes like reasoning and judgement which may be collectively called biological intelligence

17

primary visual receptor cortex

primary visual area; lesions can cause blindness in the opposite field

18 and 19

visual association areas

secondary visual areas

recognition and appreciation of visual stimuli

integrate visual information by relating current stimulus to past experiences

21 and 22

auditory association areas

on either side of area 42

22

Wernicke’s area

comprehension of language

28

olfactory area

sense of smell

37

the posterior-inferior part of the temporal lobe

39

Angular gyrus

recognition of visual symbols

40

supramarginal gyrus

symbolic integration for writing

41

Heschl’s gyrus

primary auditory area

42

immediately inferior to 41

involved in detection and recognition of speech

processing done in this area of the cortex provides a more detailed analysis

44

Broca’s area

coordinating or programming motor movements for speech sound production
