Spinothalamic Tract

Spinothalamic Tract This diagram illustrates the spinothalamic tract (also known as the anterolateral system/ventrolateral system). The spinothalamic tract is one of the ascending sensory tracts which conveys sensory information from the periphery to the central processing systems. There are three main ascending (afferent) pathways which convey sensory information: Dorsal column medial lemniscus system Spinocerebellar tracts Spinothalamic tracts (anterolateral system) The spinothalamic tract is responsible for conveying the modalities of crude touch, pressure, pain and temperature. The tract is comprised of a three neurone sequence, which terminates in the somatosensory cortex of the postcentral gyrus: First order neurone: information carried from …
