Adult Neurogenic Disorders: Week 1

Prefrontal Cortex location

Rostal end of frontal lobe

Brodmann’s areas 8, 55, 45, also, 9, 10, 11, 12, 46, and 47

Prefrontal cortex function

Associated with cognition, personality, decision making, and social behaviors

Broca’s area location

Inferior frontal gyrus of frontal lobe, between premotor cortex and prefrontal cortex

Brodmann’s areas 44/45

Broca’s area function

Language processing and speech production

Primary motor cortex location

Precentral gyrus, anterior to central fissure, posterior to premotor cortex

Brodmann’s area 4

Primary motor cortex function

Carries motor plans and sends messages to muscles to move

Premotor cortex location

Anterior to primary motor cortex, attached to length of frontal lobe to lateral fissure

Brodmann’s area 6

Premotor cortex function

Selecting and planning complex voluntary motor movements of the body

Primary sensory cortex location

Parietal lobe, anterior border along central fissure, posterior border

Brodmann’s areas 5 and 7

Primary sensory cortex function

Processes sensory information from body

Somatosensory association cortex location

Dorsal portion of parietal lobe

Brodmann’s areas 5 and 7

Somatosensory association cortex function

Influences are fine motor movements necessary for producing speech sounds

Supramarginal gyrus location

Parietal lobe

Anterior to angular gyrus, wrapped around lateral fissure (posterior end)

Brodmann’s area 40

Supramarginal gyrus function

Tied to phonological system, related to storing auditory

Angular gyrus location

Parietal lobe, around posterior end of temporal gyrus (middle)

Brodmann’s area 39

Angular gyrus function

Ability to perform reading and math related skills

Auditory cortex location

Temporal lobe 

On “ceiling” of superior temporal gyrus

Brodmann’s areas 41 and 42

Auditory cortex function

Sound processing

Wernicke’s area location

Superior temporal lobe

Brodmann’s area 22

Wernicke’s area function

Helps to create meaning to sounds we hear, specifically speech and language related

Primary visual cortex location

Occipital lobe

Brodmann’s area 17

Primary visual cortex function

Visual processing

Middle cerebral artery

Related to speech & language

Posterior cerebral artery

Related to vision/visual

Anterior cerebral artery

Related to decision making
