Brodmann Areas #

https://en.wikipedia.org/wiki/Brodmann_area#Clickable_map:_lateral_surface 567 567 These are all areas of the neocortex, with the distinction being some combination of thickness and layers the areas possess. (Strikethrough = only non-human primates)

  • BA3, BA1 and BA2 – Primary somatosensory cortex in the postcentral gyrus (frequently referred to as Areas 3, 1, 2 by convention)
  • BA4– Primary Motor Cortex
  • BA5 – Superior parietal lobule
  • BA6 – Premotor cortex and Supplementary Motor Cortex (Secondary Motor Cortex) (Supplementary motor area)
  • BA7 – Visuo-Motor Coordination
  • BA8 – Includes Frontal eye fields
  • BA9 – Dorsolateral Prefrontal Cortex
  • BA10 – Frontopolar Prefrontal Cortex (most rostral part of superior and middle frontal gyri). Rodents don’t even have one.
  • BA11 – Orbitofrontal area (orbital and rectus gyri, plus part of the rostral part of the superior frontal gyrus)
  • BA12 – Orbitofrontal area (used to be part of BA11, refers to the area between the superior frontal gyrus and the inferior rostral sulcus)
  • BA13 and BA14 – Insular cortex
  • BA15 – Anterior Temporal lobe
  • BA16 – Insular Cortex
  • BA17 – Primary Visual Cortex (V1) (Striate Cortex)
  • BA18 – Secondary visual cortex (V2)
  • BA19 – Associative visual cortex (V3, V4, V5)
  • BA20 – Inferior temporal gyrus
  • BA21 – Middle temporal gyrus
  • BA22 – Part of the superior temporal gyrus, included in Wernicke’s area
  • BA23 – Ventral posterior cingulate cortex
  • BA24 – Ventral anterior cingulate cortex.
  • BA25 – Subgenual area (part of the Ventromedial Prefrontal Cortex)
    • “Subgenual” is specific to this; not a general adjective I don’t think.
  • BA26 – Ectosplenial portion of the retrosplenial region of the cerebral cortex
  • BA27 – Presubiculum
  • BA28 – Ventral entorhinal cortex
  • BA29 – Retrosplenial cortex
  • BA30 – Subdivision of retrosplenial cortex
  • BA31 – Dorsal Posterior cingulate cortex
  • BA32 – Dorsal Anterior Cingulate Cortex
  • BA33 – In the Anterior Cingulate Cortex
  • BA34 – Dorsal entorhinal cortex (on the Parahippocampal gyrus)
  • BA35 and BA36 – Parts comprising the Perirhinal Cortex
  • BA37 – Fusiform gyrus
  • BA38 – Temporopolar area (most rostral part of the superior and middle temporal gyri)
  • BA39 – Angular gyrus, considered by some to be part of Wernicke’s area
  • BA40 – Supramarginal gyrus considered by some to be part of Wernicke’s area
  • BA41 and BA42 – Auditory cortex
  • BA43 – Primary gustatory cortex
  • BA44 BA45 – Broca’s Area, includes the opercular part and triangular part of the inferior frontal gyrus
  • BA46 – Dorsolateral Prefrontal Cortex
  • BA47 – Orbital part of inferior frontal gyrus
  • BA48 – Retrosubicular area (a small part of the medial surface of the temporal lobe)
  • BA49 – Parasubicular area in a rodent
  • BA52 – Parainsular area (at the junction of the temporal lobe and the insula)
