Fine touch tract
WebAscending tracts, such as the posterior or dorsal columns and spinothalamic tract, carry sensory information from different parts of the body to the brain. Specifically, the dorsal columns carry delicate sensations, such as vibration, fine-touch (also known as discriminative touch), and proprioception.

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 … WebTactile discrimination is the ability to differentiate information through the sense of touch.The somatosensory system is the nervous system pathway that is responsible for this essential survival ability used in adaptation.
