A[beta] neurones with specialized receptors transform mechanical deformation of the skin and transmit that signal along the spinothalamic tract to the thalamus and primary sensory cortex (see Gallace and Spence (100) for a review of tactile physiology).
Spinal afferent fiber goes upward within spinothalamic tract and spinal tract to the thalamus (spinothalamic tract) and gracile nucleus and cuneate nucleus of medulla oblongata (spinal tract), respectively, then project fiber to thalamus through lemniscus medialis.
Deep sensitivity was preserved in the patients of this study given that the pallesthesia test with tuning forks (128-256Hz) was positive in over 95% of the patients, demonstrating that leprosy only affected the superficial sensitivity transmitted through the spinothalamic pathway.
In addition, the PAG, the central area that receives signals from the thalamus, hypothalamus, cortex and the spinothalamic tract, exciting the nuclei of rostroventral medulla (RVM), exerts antinociceptive effect and inhibits the responses of the spinal cord (Perl, 2011; Steeds, 2009; Zubrzycka et al.
The spinothalamic tract carries sensory information about light touch, pain and temperature.
9),(10) These so-called lumbar spinothalamic neurons are sexually dimorphic, with males possessing greater number than females.
Pain is a fundamental function of life, and nociceptive inputs are conducted via specific pathways (the spinothalamic tract) and processed at cortical level by the so-called pain matrix, which includes both cortical areas specifically devoted to pain processing and associative areas integrating salient stimuli for the potential motor response [5].
Glycine and GABAa antagonists reduce the inhibition of primate spinothalamic tract neurons produced by stimulation in periaqueductal gray.
In an investigation on patients with intracerebral hemorrhage, a higher rate of central post-stroke pain was observed in patients with partial spinothalamic tract lesions than in patients with complete lesions (29).
Yet, spinal manipulation and afferent peripheral stimulation may result in brain hemisphere influence via descending excitation of PMRF pathways, inhibitory control of IML cell column, which may alter central integration of the brain stem and hypothalamus via spinoreticular and spinothalamic afferent direct connections.
In addition it acts as post synaptic inhibitor on the interneuron and output neuron of spinothalamic tract which transports nociceptive information.
It is based on physiological principles of interruption of anterior spinothalamic pathway by means of thermocoagulation.
