What is the spinothalamic tract

The spinothalamic tract (part of the anterolateral system or the ventrolateral system) is a sensory pathway to the thalamus. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.

Explanation:

ascending pathway of the spinal cord. Together with the medial lemnicus, it is one of the most important sensory pathways of the nervous system. It is responsible for the transmission of pain, temperature, and crude touch to the somatosensory region of the thalamus.

Damage to the spinothalamic tracts of pain and temperature usually results in loss to the opposite side of the body. Because of the extensive branching of ascending crude touch fibers, this type of touch is unlikely to be abolished by injury to a specific pathway in the spinal cord.
