<Tr> <Td_colspan="2"> Anatomical terms of neuroanatomy (edit on Wikidata) </Td> </Tr> <P> The spinothalamic tract (also known as anterolateral system or the ventrolateral system) is a sensory pathway from the skin to the thalamus . From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus . </P> <P> The spinothalamic tract consists of two adjacent pathways: anterior and lateral . The anterior spinothalamic tract carries information about crude touch . The lateral spinothalamic tract conveys pain and temperature . </P> <P> In the spinal cord, the spinothalamic tract has somatotopic organization . This is the segmental organization of its cervical, thoracic, lumbar, and sacral components, which is arranged from most medial to most lateral respectively . </P>

Where does pain information cross over in the somatosensory pathway
