Tractography-guided stimulation of somatosensory fibers for thalamic pain relief.
BACKGROUND The spinothalamocortical tract (STC) is seen as a neural tract responsible for or involved in the generation or transmission of thalamic pain. Either the thalamus itself or the posterior limb of the internal capsule (PLIC) are targets for deep brain stimulation (DBS) in patients with thalamic pain, but due to its low contrast, conventional MRI cannot visualize the STC directly. OBJ...

bookbinders. A further series of photographs was then shown of dissections of the upper brain-stem showing the 5th nerves and the structures in the vicinity of the apex of the petrous bone. Serial photographs and radio-graphs had been taken while the crushing was in progress and again at the end of each procedure when the crushing force had been released. An attempt was then made to correlate t...

The following morning there was a continuous dull ache in this hand and forearm and at least every half hour a spasm of severe pain which would last for several minutes....
متن کاملEffects of unilateral and bilateral invasion of thalamic pulvinar for pain relief.
Thalamic pulvinotomy has been performed on 32 patients in severe chronic pain and a follow-up study was made. Among 10 patients with whom unilateral invasion was made, 4 were "excellent" in relieving pain, 2 "good", 2 "fair" and 2 "poor". Among 22 cases of bilateral invasion 17 were "excellent", 2 were "good", and 3 were "poor". Thus, in the cases of bilateral invasion effects of the operation ...
متن کاملThalamic ventrobasal stimulation for pain relief. Probable mechanisms, pathways and neurotransmitters.
Thalamic ventrobasal (VB) stimulation, first performed by Mazars, in 1961, is a valuable means for treating central and deafferentation pain. The way it acts to achieve pain relief, however, is still a matter of controversy. In this paper, the author examines previously proposed hypotheses and suggests that VB stimulation induces pain relief by activation of a multisynaptic inhibitory pathway t...
