  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. Anterior white commissure - Wikipedia

    The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it provides (pain and temperature) sensory information.

  4. 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).

  5. Spinal cord - Wikipedia

    en.wikipedia.org/wiki/Spinal_cord

    Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...

  6. 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.

  7. 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 ...

  8. 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 ...

  9. Marginal nucleus of spinal cord - Wikipedia

    en.wikipedia.org/wiki/Marginal_nucleus_of_spinal...

    The neurons located here receive input primarily from Lissauer's tract and relay information related to pain and temperature sensation. [1] [2] Pain sensation relayed here cannot be modulated, e.g. pain from burning the skin. The axons of neurons contribute to the lateral spinothalamic tract. [3] [4]
