Reorganization of the central nervous system following spinal cord injury (SCI) involves changes not only at the cortical level, but also at the level of the brainstem. To further understand changes in excitatory and inhibitory brainstem interneuronal circuits following SCI, we studied recovery curves of the blink reflex (BR) to paired suprathreshold(More)
OBJECTIVE Plastic changes in the human central nervous system can occur at multiple levels, including circuits rostral to the lesion level in spinal cord injury (SCI). GABA is the most important inhibitory neurotransmitter in the brain. The authors hypothesized that one of the consequences of plasticity in SCI patients could be enhancement of brainstem(More)
BACKGROUND AND OBJECTIVES Somatic antinociceptive effects of baclofen have been demonstrated in animal models. We hypothesized that if enhanced thermal or pain sensitivity is produced by loss of gamma-aminobutyric acid (GABA)-ergic tone in the central nervous system, spinal administration of GABA agonists might be predicted to be effective in thermal and/or(More)
OBJECTIVE Paralytic poliomyelitis (pPM) is clinically suspected in individuals experiencing a non-progressive syndrome of flaccid paralysis and atrophy as a sequel of an acute infection. Despite normal sensory perception, patients with pPM complain of pain more than matched siblings. Here, we studied the characteristics of evoked pain in a cohort of pPM(More)
