COMPLETE Intro Psychology Course - ALL TOPICS - Touch, Haptic Perception, & the Somatosensory Cortex (Intro Psych Tutorial #50)

www.psychexamreview.com In this video I describe touch sensation and haptic perception, which refers to exploring the world by grasping. I outline the types of receptor in the skin including mechanoreceptors, thermoreceptors, and nocireceptors, and then discuss how signals are mapped out according to sensitivity in the somatosensory cortex of the parietal lobe. This mapping research was initially conducted by Wilder Penfield and can be used to create a “homunculus” or a representation of a little person in the cortex, which can be done for both the somatosensory cortex and the motor cortex.
