Abbreviation

Name

Function

AIP

Anterior intraparietal

visually guided grasping; comparable to monkey area F5

BA44

Brodmann's area 44

Broca's area; language production

BA46

Brodmann's area 46

rostral portion of the IFG; sustained attention and working memory

F2

Monkey area F2

integrates body position and motor acts

bF4

Monkey area F4

codes for peripersonal space; caudal part of PMv

F5

Monkey area F5

codes for distal movements; rostral part of PMv

F6

IFG

Inferior frontal gyrus

action observation and imitation

Insula

Insular cortex

body representation and subjective emotional experience

IP

Intraparietal sulcus

guidance of limb and eye movement

IPL

Inferior parietal lobule

post-central sulcus/anterior border, intraparietal sulcus/superior border, and the lateral fissure/anterior inferior border.

IT

Inferotemporal cortex

identification and categorization of objects

M1

MTG

Middle temporal gyrus

subserves language and semantic memory processing, visual perception, and multimodal sensory integration

PF
