Final answer:
Direct stimulation of brain regions associated with motivation using electrical current is achieved through transcranial magnetic stimulation (TMS).
Step-by-step explanation:
Using electrical current to directly stimulate the part of your brain which feels motivation is known as transcranial magnetic stimulation (TMS). This non-invasive method employs a rapidly varying and localized magnetic field placed near specific areas of the brain to induce weak electrical currents. Such currents can lead to the recovery of normal electrical functioning in brain tissue, and is utilized to treat various disorders including depression and hallucinations, which may be related to irregular electrical activity in the brain.
