Neural correlates of somatosensory target detection are restricted to secondary somatosensory cortex, whereas activity in insular, cingulate, and motor regions reflects stimulus uncertainty and overt reports.
Increasing microstimulation frequency in some regions of the human somatosensory cortex decreased the perceived intensity and evoked specific percepts, providing insight into cortical organization and sensory feedback approaches for brain–computer interfaces.
A combination of human imaging and brain stimulation techniques show that the somatosensory cortex is essential to prosocial decision making, by transforming observed pain in accurate perception of others' distress.
NMDAR receptors act in regulating axon guidance of somatosensory callosal projections in early postnatal life and the expression of EPHB2 receptors in target cells.
Peripheral injury induces a programmed but reversible transformation of gene expression in somatosensory neurons providing a mechanism to regulate sensory input during wound healing.
Area 2 of somatosensory cortex represents kinematic details of the entire arm during movement, but this mapping from limb state to neural activity differs for reaching and passive limb displacement.
A combination of 7 tesla fMRI and psychophysics revealed the reorganisation of the human somatosensory cortex and changes in tactile perceptual abilities after just 24 hours of altered hand use.
