摘要: Abstract Transcutaneous spinal direct current stimulation (tsDCS) is a noninvasive method that can modulate reflexes, sensory afferent conduction, and even pain perception. Although neurophysiological evidence suggests tsDCS alters somatosensory nociceptive conduction to the cortex, its supraspinal effects have not yet been investigated by using functional imaging investigate tsDCS-induced alterations in intrinsic connectivity (FC). Therefore, we hypothesize changes measures might also be reflected spontaneous brain activity. We cortical seed-to-voxel-based analyses from bilateral primary cortex (S1) thalamus double-blind, crossover study design. Resting state FC was measured blood oxygenation level-dependent, magnetic resonance (3T Philips) before after anodal, cathodal, sham (2...
