Electrolytic research proceduresStimulation -- If the electrical current passed through the electrode is weak, the target region of the brain is stimulated but not damaged. Generally, this stimulation crudely activates the type of behavior contolled by the target region; if the target region's function was to inhibit a behavior, then that behavior will occur less frequently during the stimulation.Destruction -- If the electric current passed through the electrode is strong, the target region of the brain is damaged. This destruction is called a lesion. A lesion generally suppresses or disrupts the type of behavior associated with the target region; if the target region's function was to inhibit a behavior, then that behavior will occur more frequently or in an uncontrolled fashion after the lesion. |
