2-Minute Neuroscience: Primary Somatosensory Cortex

In this video, Neuroscientifically challenged discusses the primary somatosensory cortex. The primary somatosensory cortex is responsible for processing somatic sensations, or sensations from the body that include touch, proprioception (i.e. the position of the body in space), nociception (i.e. pain), and temperature. The primary somatosensory cortex is generally divided into 4 areas: area 3a, 3b, 1, and 2. In the video, Neurosciencetifically challenged discusses the relative functions of each of these areas.
