Few people have damage in just one brain area. Researchers often turn to producing carefully localized damage in laboratory animals because doing so in a human being is unethical. Ablation removal of a brain area, generally with a surgical knife. Lesion damage to a brain area/structure and is generally done with a stereotaxic instrument (a device for the precise placement of electrodes in the brain) Electric lesion technique of lesion that damages the axons passing by that area as well as the neurons in the area itself; this method is less often used today. Lesion method that is more often used today involves the injection of chemicals that kill or disable neurons temporarily without harming the passing axons.
