  • Here, objects are recognized based on their form and texture.
  • A sense of body image is also formed using integrated information sent from the visual and auditory cortex areas.
  • If this area is damaged, an individual may ignore certain body regions (neglect syndrome) or not be able to recognize objects from their feel (agnosia).
  • Output from the primary somato-sensory cortex also travels to the image descriptionsecondary somatosensory cortex or SII.

  • This small area is located in the inferior parietal lobe adjacent to the lateral fissure (Broadmann area 40).
  • The structure and functions of the secondary somatosensory cortex areasĀ are not yet well understood.
  • Each SII area receives and integrates somatosensory information from both sides of the body (bilateral).
  • Studies also indicated that they participate in sensorimotor integration, maintaining attention while objects are touched, learning, and memory.
