Extracellular potassium accumulation in the frog spinal cord induced by stimulation of the skin and ventrolateral columns

RESUMO

1. Changes in extracellular K+ concentration (Δ[K]e), dorsal root potentials (DRPs) and single unit activity were studied in the frog spinal cord in response to stimulation of the skin of the hindlimb by touch, pressure, hot water (heat), single electrical pulses and to stimulation of the ventrolateral columns (LC).
