Excitation of dorsal column nucleus neurons by air-jet moving across the skin

Abstract

Single unit recordings from dorsal column neurons were made during application of mechanical somatic stimuli moving at controlled velocities across the neuron's receptive field. The neurons responded in stereotypic patterns which changed with altered stimulus parameters of velocity, direction and intensity. Spatial analysis of the response patterns indicates that the neurons generate action potentials when the stimulus probe activated particular discrete locations within the receptive field.
