location of primary motor cortex

location of primary motor cortex

precentral gyrus (PrCG) on frontal lobe

fxn of primary motor cortex

drives motor neurons used for voluntary intentional skeletal muscle movements via pyramidal neurons projecting through the pyramidal tract

location of premotor cortex

anterior to PrCG on frontal lobe

fxn of premotor cortex

planning of learned skilled motor activites requiring driving of several muscle groups (e.g. typing, bicycling, etc)

location of frontal eye field

anterior to premotor cortex on frontal lobe

fxn of frontal eye field

drives motor neurons for voluntary intentional eye movements

location of Broca's area

left hemisphere and inferior to premotor cortex and frontal eye field on frontal lobe

fxn of Broca's area

plans and drives motor neurons for muscles involved in speech

location of prefrontal cortex (aka anterior association areas)

anterior to frontal eye field and surrounding Broca's on frontal lobe

fxn of prefrontal cortex

intellect, personality, complex learning activities. Site of reasoning and abstract ideas.

location of primary somatosensory area

Postcentral gyrus (PsCG) on parietal lobe

fxn of primary somatosensory area

Recieves ascending sensory info via thalamus for touch, temp, pain, pressure, and proprioception. Enables spatial discrimination.

location of somatosensory association area

posterior to PsCG on parietal lobe

fxn of somatosensory association area

receives somatosensory info from primary somatosensory area to enable recognition of somatosensory objects by relating raw somatosensory data to memory

location of gustatory area

inferior portion of parietal lobe deep to lateral sulcus

fxn of gustatory area

recieves ascending info on taste from thalamus

location of primary visual cortex

posterior tip of occipital lobe

fxn of primary visual cortex

maps of ascending visual info from thalamus on color, shape, and contrast

location of visual association area

anterior and surrounding to primary visual area on the occipital lobe

fxn of visual association area

receives visual info from primary visual cortex to enable recognition of location and features of visual stimuli

location of multimodal association areas (aka gnostic areas)

parietal lobe anterior to visual areas and posterior and inferior portions of temporal lobe

fxn of multimodal association areas

integrates multiple sensory inputs from the association areas relate to memory and to utilize in the premotor and prefrontal areas. includes limbic areas.

location of primary auditory area

superior margin of temporal lobe just below central sulcus

fxn of primary auditory area

receives ascending auditory info from thalamus regarding location, pitch, tone, and loudness of sounds

location of auditory association area

surrounding and posterior to primary auditory area on temporal lobe

fxn of auditory association area

recieves auditory info from primary auditory area to recognize sounds and relate sounds to past experiences

location of wernicke's area (part of multimodal area)

posterior to auditory association on left hemisphere's parietal lobe. considered part of multimodal area

fxn of wernicke's area

enables understanding of written and spoken language
