WebThe lateral spinothalamic tract (or lateral spinothalamic fasciculus ), is a bundle of afferent nerve fibers ascending through the white matter of the spinal cord, in the spinothalamic tract, carrying sensory information to the brain. It carries pain, and temperature sensory information ( protopathic sensation) to the thalamus.
