The 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.
The spinohypothalamic tract or spinohypothalamic fibers is a sensory fiber tract projecting from the spinal cord to the hypothalamus directly to mediate reflex autonomic and endocrine responses to painful stimuli (the hypothalamus receives additional indirect nociceptive projections from the reticular formation (see: spinoreticular tract), and periaqueductal gray (see: spinomesencephalic tract).
Ventral posterolateral nucleus, which receives sensory information from the body via the medial lemniscus, and spinothalamic tracts. Ventral posteromedial nucleus , which receives sensory information from the head and face via the trigeminal nerve .
Its fibres are carried in the spinothalamic tract, unlike the fine touch, which is carried in the dorsal column. [ 23 ] As fine touch normally works in parallel to crude touch, a person will be able to localize touch until fibres carrying fine touch (in the dorsal column–medial lemniscus pathway) have been disrupted.
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.

This tract was historically considered a cephalic division of the medial lemniscus due to the close proximity of the two ascending tracts. [2] Like the medial lemniscus in the dorsal column-medial lemniscus pathway (DCML), that carries mechanosensory information from part of the head and the rest of the body, the trigeminal lemniscus carries ...
The spinomesencephalic pathway, spinomesencephalic tract or spino-quadrigeminal system of Mott, includes a number of ascending tracts in the spinal cord, including the spinotectal tract. [ 1 ] [ 2 ] [ 3 ] The spinomesencephalic tract is one of the ascending tracts in the anterolateral system of the spinal cord that projects to various parts of ...
