Functional Organization of the Sympathetic Pathways Controlling the Pupil: Light-Inhibited and Light-Stimulated Pathways

open access: yesFrontiers in Neurology, 2018
Pupil dilation is mediated by a sympathetic output acting in opposition to parasympathetically mediated pupil constriction. While light stimulates the parasympathetic output, giving rise to the light reflex, it can both inhibit and stimulate the ...

Impaired Autophagy of GABAergic Interneurons in Neuropathic Pain

open access: yesPain Research and Management, 2018
Neuropathic pain (NP) is caused by lesions of the peripheral fibers and central neurons in the somatosensory nervous system and affects 7–10% of the general population.

Intrapericardiac injections of algogenic chemicals excite primate C1-C2 spinothalamic tract neurons

open access: yes, 2000
Extracellular potentials of 38 C1-C2 spinothalamic tract (STT) neurons in anesthetized monkeys ( Macaca fascicularis) were examined for responses to intrapericardiac injections of an algogenic chemical mixture (adenosine, 10−3 M; bradykinin ...

Segmental and laminar organization of the spinothalamic neurons in cat:Evidence for at least five separate clusters

open access: yes, 2005
The spinothalamic tract (STT), well known for its role in the relay of information about noxe, temperature, and crude touch, is usually associated with projections from lamina I, but spinothalamic neurons in other laminae have also been reported. In cat,

Nitric Oxide–Mediated Spinal Disinhibition Contributes to the Sensitization of Primate Spinothalamic Tract Neurons

open access: yes, 1999
Nitric oxide–mediated spinal disinhibition contributes to the sensitization of primate spinothalamic tract neurons. This study concentrated on whether an increase in spinal nitric oxide (NO) diminishes inhibition of spinothalamic tract (STT) cells ...

Nitric Oxide Mediates the Central Sensitization of Primate Spinothalamic Tract Neurons

open access: yes, 1999
Nitric oxide mediates the central sensitization of primate spinothalamic tract neurons. Nitric oxide (NO) has been proposed to contribute to the development of hyperalgesia by activating the NO/guanosine 3′,5′-cyclic monophosphate (cGMP) signal ...

Analysis of the Perception of and Reactivity to Pain and Heat in Patients With Wallenberg Syndrome and Severe Spinothalamic Tract Dysfunction

open access: yes, 1999
Background —The aim of the study was to assess the consequences of severe spinothalamic tract lesions resulting from lateral medullary infarct and to show that a specific pain perception can be elicited by strong thermal ...

Neuropathic Pain and Its Relationship with Quality of Life in 72 Patients with Spinal Cord Injury

open access: yesGlobal Spine Journal, 2015
Introduction Approximately 80% of the patients with spinal cord injury (SCI) suffer from neuropathic pain. Some methods exist for evaluating neuropathic pain, but they have not been rigorously validated.
