4/16/2023 0 Comments Brain stimulator![]() The brain itself has no pain receptors so does not require anaesthetic.įollowing recovery from surgery the electrodes are activated and the current calibrated by a neurologist to determine the optimal stimulation parameters. This ensures that the electrode does not damage critical brain regions. The neurosurgery is conducted under local anaesthetic to maintain consciousness in the patient. This stimulation evokes control over the neural activity within these regions. Prior to switching on the electrical stimulation, electrodes are surgically implanted within precise brain regions to control a specific function.In a similar manner, DBS sends electrical impulses to specific parts of the brain that control discrete functions. Deep-brain stimulation: a pacemaker for the brainĪrtificial cardiac pacemakers are typically associated with controlling and resynchronising heartbeats by electrical stimulation of the heart muscle. But what if there was a way to simply switch off a devastating tremor, or boost a fading memory?Īdvances using Deep Brain Stimulation ( DBS) in selective brain regions have provided therapeutic benefits and have allowed those affected by these neurological disorders freedom from their symptoms, in absence of an existing cure. Symptoms of these disorders differ extensively - from motor dysfunction in Parkinson’s disease, memory loss in Alzheimer’s disease to inescapable cravings in drug addiction.ĭrug treatments are often ineffective in these disorders. ![]() Neurological disorders can have a devastating impact on the lives of sufferers and their families. ![]()
