Functional Anatomy of Somatosensory Cortex and Somatosensory Homunculus

Watch this video if you want to learn about different functional areas of parietal lobe. The parietal lobe is divided into various somesthetic areas: primary, secondary, and association areas. The location of each somesthetic area, along with Brodmann’s classification, is described. The function of each area and the somatosensory homunculus are also explained. Input and output of somatosensory cortex are defined. The significance of area 1 and area 2 are discussed in depth. 0:09 Somesthetic areas 1:26 Ascending somatosensory pathways 2:05 Somatosensory homunculus 5:51 Input to somatosensory cortex 9:01 Output from somatosensory cortex 10:52 Area 1 function 12:06 Area 2 function
