Structural connectivity standard of the human sensory-motor cortex
In the 19th century, Gratiolet created the term plis de passage, which was mapped by the neurosurgeon Jean Regis to describe gyri that were interconnected and anatomically covered by main sulci. Besides, Cunningham characterized the plis de passage, which binds the precentral gyrus, associated to the hand´s primary motor area, and the postcentral gyrus, associated to the hand´s somatosensory area, having become a subject of interest with the advent of imaging tests.
