WebNov 13, 2024 · The primary somatosensory cortex is found in the postcentral gyrus and is one of the sections of the somatosensory system (1). Also, the somatosensory system is … All afferent touch/vibration info ascends the spinal cord via the dorsal column-medial lemniscus pathway via gracilis (T7 and below) or cuneatus (T6 and above). Cuneatus sends signals to the cochlear nucleus indirectly via spinal grey matter, this info is used in determining if a perceived sound is just villi noise/irritation. All fibers cross (left becomes right) in the medulla. A somatosensory pathway will typically have three neurons: first-order, second-order, and third-o…
