Lateral view of the cerebral cortex showing the principal gyri and sulci. Major structures include the central sulcus and the precentral (primary motor), premotor, and postcentral (primary somatosensory) gyri. Also note the gyri situated rostral to the premotor cortex, including the orbital gyri, which mediate higher order intellectual functions and contribute to the regulation of emotional behavior. Brocas motor speech area and Wernickes area (for reception of speech) are important areas…

Neuroscientists show how brain responds to sensual caress

A nuzzle of the neck, a stroke of the wrist, a brush of the knee -- these caresses often signal a loving touch, but can also feel highly aversive, depending on who is delivering the touch, and to whom. Interested in how the brain makes connections between touch and emotion, neuroscientists at the California Institute of Technology (Caltech) have discovered that the association begins in the brain's primary somatosensory cortex, a region that, until now, was thought only to respond to basic…

Somatosensory Cortex Linked to Increased Sensitivity to Touch in Fibromyalgia

The somatosensory cortex of people with fibromyalgia is more excitable and thus more likely to interpret touch as painful.

Postcentral gyrus - the primary somatosensory cortex

“The relative sizes of different sensory representations in naked mole-rats S1. The chart on the right shows the percentage of cortex devoted to different body parts. On the left the different body parts are illustrated according to their cortical proportions. This “mole-ratunculus” provides a graphic illustration of the cortical magnification of the incisors and head (illustration by Lana Finch).” ‘Somatosensory cortex dominated by the representation of teeth in the naked mole-rat brain’
