Long-lasting Changes in the Level of the Electrical Activity of the Cerebral Cortex produced by Polarizing Currents

摘要: THE passage of direct current produces changes in the electrical activity nervous tissue. For example, polarization nerve terminals muscle spindles gives rise to alterations membrane potential; a depolarization an increased rate discharge impulses while hyperpolarization decreases frequency1. A similar effect can be produced by spinal cord2; ventral roots is altered small currents across thickness cord.
