Even if you might be eligible for deep brain stimulation, you and your doctors must carefully weigh the risks and potential benefits of the procedure. How you prepare First, weigh the pros and consĭeep brain stimulation is a serious and potentially risky procedure.
Temporary pain and swelling at the implantation siteĪ few weeks after the surgery, the device will be turned on and the process of finding the best settings for you begins.Hardware complications, such as an eroded lead wire.Side effects associated with deep brain stimulation may include:

Surgery risksĭeep brain stimulation involves creating small holes in the skull to implant the electrodes into the brain tissue as well as performing surgery to implant the device that contains the batteries under the skin in the chest. Also, the brain stimulation itself can cause side effects. Only the first and the second pair emerge from the cerebrum the remaining ten pairs emerge from the brainstem.Although deep brain stimulation is generally considered to be low risk, any type of surgery has the risk of complications. In humans, there are traditionally twelve pairs of cranial nerves.
Human Brain with Cranial Nerves: Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord. The brainstem also has integrative functions, including cardiovascular system control, respiratory control, pain sensitivity control, alertness, awareness, and consciousness. In addition, upper motor neurons originate in the brain stem’s vestibular, red, tectal, and reticular nuclei, which also descend and synapse in the spinal cord.
The facial sensations have similar pathways and also travel in the spinothalamic tract and the medial lemniscus.ĭescending tracts are upper motor neurons destined to synapse on lower motor neurons in the ventral horn and intermediate horn of the spinal cord. The ascending pathways from the body to the brain are the sensory pathways, including the spinothalamic tract for pain and temperature sensation and the dorsal column, fasciculus gracilis, and cuneatus for touch, proprioception, and pressure sensation. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem. The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It regulates the central nervous system (CNS) and is pivotal in maintaining consciousness and regulating the sleep cycle. The brain stem also plays an important role in the regulation of cardiac and respiratory function. This includes the corticospinal tract (motor), the posterior column-medial lemniscus pathway (fine touch, vibration sensation, and proprioception ) and the spinothalamic tract ( pain, temperature, itch, and crude touch).
Though small, it is an extremely important part of the brain, as the nerve connections of the motor and sensory systems from the main part of the brain that communicate with the peripheral nervous system pass through the brainstem. The brainstem gives rise to cranial nerves 3 through 12 and provides the main motor and sensory innervation to the face and neck via the cranial nerves. In vertebrate anatomy, the brainstem is the most inferior portion of the brain, adjoining and structurally continuous with the brain and spinal cord.
