Brown-Sequard syndrome is a rare neurological disorder characterized by ipsilateral motor paralysis caused by a lesion through corticospinal tract and contralateral loss of pain and temperature sensation due to the involvement of spinothalamic tract. Cervical disc herniation has been reported to be a rare cause of Brown-Séquard's syndrome. This paper aims to report a case of Brown-Sequard syndr...

The respective roles of the ventral posterior complex (VP) and of the more recently described VMpo (posterior part of the ventral medial nucleus) as thalamic relays for pain and temperature pathways have recently been the subject of controversy. Data we obtained in one patient after a limited left thalamic infarct bring some new insights into this debate. This patient presented sudden right-sid...

Lin, Qing, Jing Wu, Yuan Bo Peng, Minglei Cui, and William D. Willis. Inhibition of primate spinothalamic tract neurons by spinal glycine and GABA is modulated by guanosine 39,59-cyclic monophosphate. J. Neurophysiol. 81: 1095–1103, 1999. Our recent work has suggested that the nitric oxide/guanosine 39,59-cyclic monophosphate (NO/cGMP) signal transduction system contributes to central sensitiza...

In six monkeys spinothalamic (STT) cells were retrogradely labeled by injecting 2% wheat germ agglutinin-conjugated horseradish peroxidase into the somatosensory thalamus. Following a 5-day survival period, the animals were perfused and the tissue was removed and processed with the tetramethyl benzidine technique. In all animals there were HRP-labeled STT cells in all segments of the spinal cor...

The mouse hind footpad inoculation model has served as a standard laboratory system for the study of the neuropathogenesis of herpes simplex virus type 1 (HSV-1) infection. The temporal and spatial distribution of viral antigen, known as the transneuronal spread phenotype, has not previously been described; nor is it understood why mice develop paralysis in an infection that involves sensory ne...
