Frontal Lobe - cognitive functioning and in speech and language.
• Area 4 corresponds to the precentral gyrus or primary motor area.
• Area 6 is the premotor or supplemental motor area.
• Area 8 is anterior of the premotor cortex. It facilitates eye movements and is involved in visual reflexes as well as pupil dilation and constriction.
• Areas 9, 10, and 11 are anterior to area 8. They are involved in cognitive processes like reasoning and judgement which may be collectively called biological intelligence.
• Area 44 is Broca's area.
Parietal Lobe - somatosensory processes.
• Areas 3, 2, and 1 are located on the primary sensory strip, with area 3 being superior to the other two. These are somastosthetic areas, meaning that they are the primary sensory areas for touch and kinesthesia.
• Areas 5, 7, and 40 are found posterior to the primary sensory strip and correspond to the presensory to sensory association areas.
• Area 39 is the angular gyrus.
Temporal Lobe - processing of auditory information and semantics as well as the appreciation of smell
• Area 41 is the primary auditory area.
• Area 42 immediately inferior to area 41 and is also involved in the detection and recognition of speech. The processing done in this area of the cortex provides a more detailed analysis than that done in area 41.
• Areas 21 and 22 are the auditory association areas. Both areas are divided into two parts; one half of each area lies on either side of area 42.
• Area 37 is found on the posterior-inferior part of the temporal lobe.
Occipital Lobe - process visual stimuli.
• Area 17 is the primary visual area.
• Areas 18 and 19 are the secondary visual areas.
