In the context of functional neurosurgery, the procedure used is based on the use of electrical stimulation in order to correct the function of neural tissue – the nerve tissue. The treatment includes areas of the brain, spinal cord and peripheral nerves.
During The Procedure:- The surgeons use an implantable pulse generator, which has a thin insulated wire with four micro-electrodes attached to its tip. The team of highly experienced surgeons implant these micro-electrodes in the area of the brain, spinal cord or an occipital nerve and position it with sub-millimeter accuracy using state-of-the-art surgical navigation technology.
After the procedure : -After recovery, the affected area is stimulated with the help of a surgically implanted stimulator, resembling a heart pacemaker. This is implanted under the skin of the chest. It is used to deliver the small pulses of electricity to the target area. The adjustment of the stimulation parameters of the implant are done across a wide range, which helps in relieving symptoms. This implanted system helps in changing the functioning of the brain (the ultimate neural structure), the spinal cord, cranial nerves, and the peripheral nerves.
Some of the common procedures performed using Functional Neurosurgery are:
- Deep Brain Stimulation: In this technique, a doctor uses electricity to change the function of the brain.
- Spinal Cord Stimulation: In this technique, a doctor uses electricity to alter the function of the spinal cord.
- Occipital Nerve Stimulation: In this technique, a doctor uses electricity to change the functioning of the occipital nerve.
