Deciding the extent to which pain qualities are dependent on the activation of subpopulations of neurons and depth coding poses a considerable challenge and it is an Lively space of exploration (thirteen). Psychophysical studies on spinal cord personal injury patients struggling from partial or comprehensive loss of thermal sensitivity assistance a model by which each pain-distinct pathways and nonnociceptive pathways are integrated (117). Significant crosstalk amongst these pathways exists at various levels together with stimulus transduction (118), peripheral terminals for the duration of neurogenic inflammation, and central connections in click here the course of central sensitization and should underlie paradoxical temperature feeling.
