  2. Spinothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Spinothalamic_tract

    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.

  3. Spinohypothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Spinohypothalamic_tract

    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).

  4. Ventral posterior nucleus - Wikipedia

    en.wikipedia.org/wiki/Ventral_posterior_nucleus

    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 .

  5. Ventrobasal complex - Wikipedia

    en.wikipedia.org/wiki/Ventrobasal_complex

    Spinothalamic tract (STT) cells that project from laminae I and V in the lumbosacral area of the spinal cord project to the VPL in the VB. [2] STT cells located in the cervical area of the spinal cord are the densest and project from the neck of the dorsal horn to the VPL of the VB. Most projections to the VB are contralateral while only a few ...

  6. Spinomesencephalic pathway - Wikipedia

    en.wikipedia.org/wiki/Spinotectal_tract

    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 ...

  7. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    Crude touch (non-discriminating) is a sensory modality that allows the subject to sense that something has touched them, without being able to localize where they were touched (contrasting "fine touch"). Its fibres are carried in the spinothalamic tract, unlike the fine touch, which is carried in the dorsal column.

  8. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    The spinothalamic tract is a sensory pathway originating in the spinal cord. It transmits information to the thalamus about pain, temperature, itch and crude touch . There are two main parts: the lateral spinothalamic tract , which transmits pain and temperature, and the anterior (or ventral) spinothalamic tract , which transmits crude touch ...

  9. Periaqueductal gray - Wikipedia

    en.wikipedia.org/wiki/Periaqueductal_gray

    The ascending pain and temperature fibers of the spinothalamic tract send information to the PAG via the spinomesencephalic pathway (so-named because the fibers originate in the spine and terminate in the PAG, in the mesencephalon or midbrain). This region has been used as the target for brain-stimulating implants in patients with chronic pain.
