Brubeck’s "Take Five" helped me to understand this pentagonal brain universe. David Warren Brubeck died on Dec. 05, 2012, morning. I heard his "Take Five" for the first time when I was about 15 years old and even with my then very limited capacity to understand jazz music, I was greatly impressed by that piece. "Take Five" (that became the Brubeck quartet's theme) was a musical milestone deviated from the standard 4/4 time (or 3/4 waltz time) of Western music using the unusual quintuple (5/4) time. This CEREBRART work illustrates Brubeck’s pentagonal universe.

Fishes use a special sensory system to obtain information about minute water movements: the lateral line system. The lateral line system decodes the information in the water surrounding the fish to enable the fish to identify and localize the source of the perturbation. From the lateral-line system of fishes evolved the vestibular system of terrestrial vertebrata which deals with equilibrium and position in space and ascending thalamocortical projection from the vestibular nuclei to the insular cortex which is important in the conscious awareness of head motion, balance, orientation, appropriate actions and integration/memorization of the paths taken. Likely, the insula is one of the most changed regions of the human brain. This CEREBRART work illustrates an evolutionary trend in the island of Reil development.

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.
