Question

Implanting an electrode that supplies a weak electrical current to specific brain areas is called _____. It is useful in the treatment of _____

Answer 1

Answer:

Deep Brain Stimulation (DBS)

Depression, Uncoordinated body movements such as in Parkinson's disease

Explanation:

Deep brain stimulation is a surgical procedure in which a device that sends electrical impulses to the brain by means of lead wires connected to electrodes placed in the specific areas of the brain, is implanted in the body, typically the chest region.

This surgical procedure is usually required to treat diseases in which there is irregular and improper nervous stimulation of the brain resulting in various nervous disorders such as irregular muscle movements as in Parkinson's disease as well as depression.

The impulses sent from the stimulator device to the electrodes in the brain through the wires, serves to stabilize and normalize nerve signals sent to the brain.
