Spontaneous activities (SP) and responses to a series of stimuli. BA: response to balloon inflation at 200 kPa in the medullary cavity of the femur; Depth: depths of electrodes from the surface of the spinal cord; BR: response to brush stimulation; VF4: response to punctate stimulation using a 4-g von Frey filament; PI: response to pinch stimulation by an arterial clip that exerts a force of 250 g/mm2; WDR: wide-dynamic-range neurons; HT: high-threshold neurons; LT: low-threshold neurons; —: not recorded. Data are shown as means ± SEMs.
