Brodmann's area

Introduction

A classification of areas of the cerebral cortex according to assigned numbers.

Classification

• primary sensory cortex & motor cortex
  • primary visual cortex, striate cortex (area 17)
  • primary auditory cortex (areas 41, 42)
  • primary somatosensory cortex (areas 1, 2, 3 but mostly 3b)
  • primary motor cortex (area 4)
• unimodal association cortex
  • unimodal visual cortx
    • peristriate cortex, upstream visual cortex (areas 18, 19)
    • downstream visual association cortex (area 37)
  • unimodal auditory cortex (area 22)
  • unimodal somatosensory cortex (area 5, rostral area 7)
  • unimodal motor cortex, premotor cortex (areas 6, caudal 8, 44)
• heteromodal association cortex
  • heteromodal prefrontal cortex (areas 9, 10, 45, 46, 47, rostral parts of 11, 12, 32)
  • heteromodal parietotemporal cortex (areas 39, 40, caudal parts of area 7, banks of superior temporal sulcus, area 36)
• paralimbic cortex
  • insula (areas 14, 15)
  • temporopolar cortex (area 38)
  • caudal orbitofrontal cortex (caudal areas 11, 12)
  • cingulate complex (areas 23, 24, 31, 33, 25, 26, 29,caudal parts of area 32)
  • parahippocampal cortex (areas 28, 34, 35, 30)
