Electrical brain stimulation variety of treatments, such as for Parkinson's disease, focal epilepsy and psychosurgery. Sometimes the same electrode is used to probe the brain for finding defective functions, before passing the lesioning current (electrocoagulation). Electrical brain stimulation Electrical brain stimulation (EBS), also referred to as focal brain stimulation (FBS), is a form of electrotherapy and technique used in research and clinical neurobiology to stimulate a neuron or neural network in the brain through the direct or indirect excitation of its cell membrane by using an electric current. It is used for research or for therapeutical purposes. Electrical brain stimulation was first used
Cochlear implant sound into movements of hair cells in the cochlea; the inside-portion of these hair cells release potassium ions in response to the movement of the hairs, and the potassium in turn stimulates other cells to release the neurotransmitter, glutamate, which makes the cochlear nerve send signals to the brain, which creates the experience of sound. Instead, the devices pick up sound and digitize it, convert that digitized sound into electrical signals, and transmit those signals to electrodes embedded in the cochlea. The electrodes electrically stimulate the cochlear nerve, causing it to send signals to the brain. There are several systems
