Divisions -Of The Cerebral  Cortex

Primary Sensory Cortex: 

• Visual (area 17)
• Auditory (areas 41, 42)
• Somatosensory (areas 3, 1, 2, and predominantly 3b)

Primary Motor Cortex:

• Area 4 and the caudal portion of
  Area 6

Association Cortex:

• Unimodal Visual
  (areas 18, 19, 20, 21, 37)
• Unimodal Auditory (area 22)
• Unimodal Somatosensory
  (area 5, and the rostral portion of area 7)
• Unimodal Motor
  (rostral area 6, caudal area 8, and area 44)
• Heteromodal preFrontal
  (areas 9, 10, 11, 45, 46, 47, rostral area 8, rostral area 12, and rostral area 32)
• Heteromodal ParietoTemporal
  (areas 39, 40, caudal area 7, banks of superior Temporal sulcus, area 36)

Limbic System:

• Paralimbic cortex
    (Insula; Temporopolar cortex- area 38; caudal orbitoFrontal cortex- caudal area 12, 13; Cingulate complex- areas 23, 24, 33, 31, 26, 29; paraOlfactory region- area 25, caudal area 32; paraHippocampal cortex- areas 28, 34, 35, 30)
  
  
• Core Limbic formations
    (Hippocampus, Amygdala, Substantia innominata, Septal nuclei, Pyriform Olfactory cortex)
  
  
• Limbic Basal Ganglia and related structures
    (nucleus accumbens, medial Globus Pallidus, ventral tegmental area of Tsai, Habenula)
  
  
• Limbic Thalamus
    (midline nuclei, anterior tubercle nuclei, laterodorsal nucleus, dorsomedial nucleus, medial pulvinar nucleus)
  
  
• Hypothalamic nuclei
