Nuclei in which functionally identified spinothalamic tract neurons terminate. 1979

A E Applebaum, and R B Leonard, and D R Kenshalo, and R F Martin, and W D Willis

The approximate level of termination of the axons of individual, functionally characterized spinothalamic tract neurons within the monkey thalmus was mapped by antidromic activation using a monopolar electrode which was moved in a systematic grid of tracks through the thalamus. The course of individual axons could be followed through several thalamic levels, and in a few cases branches to both the VPL nucleus and to the intralaminar nuclei were demonstrated. Most of the axons studied, however, projected just to the VPLc or VPLo nuclei. The spinothalamic tract cells that projected to the VPLc nucleus included representative of all known functional categories: low threshold, wide dynamic range, high threshold and "deep." It is speculated that these different classes of spinothalamic projections could make contributions to such sensory modalities as touch, proprioception and pain.

D008465 Mechanoreceptors Cells specialized to transduce mechanical stimuli and relay that information centrally in the nervous system. Mechanoreceptor cells include the INNER EAR hair cells, which mediate hearing and balance, and the various somatosensory receptors, often with non-neural accessory structures.

D011434 Proprioception Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000882 Haplorhini A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes).

D013133 Spinothalamic Tracts A bundle of NERVE FIBERS connecting each posterior horn of the spinal cord to the opposite side of the THALAMUS, carrying information about pain, temperature, and touch. It is one of two major routes by which afferent spinal NERVE FIBERS carrying sensations of somaesthesis are transmitted to the THALAMUS. Spinothalamic Tract,Tract, Spinothalamic,Tracts, Spinothalamic
D013787 Thalamic Nuclei Several groups of nuclei in the thalamus that serve as the major relay centers for sensory impulses in the brain. Nuclei, Thalamic
