This device delivers electrical impulses to specific regions of the brain, modulating abnormal neuronal activity and restoring balance. By targeting specific circuits, DBS helps alleviate symptoms of various neurological and psychiatric disorders.
When it comes to understanding the science behind DBS, it is crucial to delve into the intricate workings of the brain. The brain is a complex organ composed of billions of neurons that communicate with each other through electrical signals. In individuals with neurological or psychiatric disorders, these electrical signals become disrupted, leading to the manifestation of symptoms. DBS aims to restore the normal functioning of the brain by precisely modulating these electrical signals.
Through the use of advanced imaging techniques, neurosurgeons identify the specific brain regions that need to be targeted for stimulation. Once the target areas are determined, the neurostimulator is implanted, usually in the subthalamic nucleus or the globus pallidus. These regions play a crucial role in motor control and are often affected in movement disorders like Parkinson’s disease.
Once the neurostimulator is in place, it is connected to thin wires, known as leads, which are also implanted in the brain. These leads act as conduits for the electrical impulses, delivering them precisely to the targeted areas. The neurostimulator is typically placed under the skin, usually in the chest or abdomen, and is programmed to deliver the appropriate amount of electrical stimulation.
It is important to note that DBS is not a cure for neurological and psychiatric disorders. Instead, it serves as a powerful tool for symptom management and improvement in the quality of life.
