CEREBRART - PAIN INFORMATION
So, pain information generates both sensations and motivations to act and is distributed to many brain areas, which reflects its tremendous evolutionary significance for survival. The central processing of pain information includes transmission to brain stem centers, where autonomic nervous system responses are recruited, to the limbic system, where the emotional components of pain are experienced, and to the cortex, where pain information is perceived and interpreted, It has been shown that painful stimuli activate a vast network of cortical areas, involved in the generation of painful percepts and including the primary and secondary somatosensory cortex, the insula, posterior parietal cortex, anterior and mid-cingulate cortex, and parts of the prefrontal cortex. This CEREBRART work illustrates nociceptive regions in parasylvian cortex that are involved in processing pain information.
