The Brain Pacemaker

Good Essays

The brain pacemaker is an interesting invention of the modern technology, it is a medical device that is fixed into the brain to send electroshock signals into the targeted tissues of the brain. This device is used to treat patients who suffer from Epilepsy, it controls their seizures, and helps Parkinson's disease patients better control their movements. Parkinson's disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Plus, it treats major depression.

What is it?

It is a surgical treatment that involves the implantation of a medical device that is either placed in the brain or outside. It sends electrical impulses to specific parts of the brain. When it placed in the brain this treatment is called deep brain stimulation. And when it is placed out side the brain or near the spinal cord it is called spinal cord stimulation, there is another place where it can be placed outside which is around cranial nerves such as the vagus nerve and it is called vagus nerve stimulation.

How it works?

The doctor drills into the skull of the patient who remains awake during operation two holes, they are the size of a coin. Only that area is anesthetized to keep it numb during surgery.

Surgeons then uses computed tomography (CT) scanning to locate the exact targeted area, and then implant two thin wires with electrode contacts near the Cg25 area of the brain. In the area where they believe is causing the patient's disorder. Generally, these targets are the thalamus, subthalamic nucleus, and globus pallidus.

Then they stitch the loose end of the wires under the skin and attach it to the pacemaker device, which is fixed near the collarbone. In some cases it may be implante...

...rchers found that when Parkinson's patients received brain stimulation, they had trouble making hard decisions.

? Because the brain can shift slightly during surgery, there is the possibility that the electrodes can become displaced or dislodged this might cause some problems such as personality changes.

? There are other complications of surgery, such as bleeding within the brain.


The brain is the center of thought, emotion, memory, speech, and many more, and it is the most sophisticated organ in the human body. By it doctors were able to help patients who suffer from Epilepsy, Parkinson's disease and sever depressions by inserting a device called brain pacemaker. It has already helped many patients to overcome their problems. But scientists are still experimenting in making this device more advanced to reduce the number of risks it may cause.
