Chronic brain-computer interfaces come in two varieties, stimulating and recording. Applications for stimulating interfaces include sensory prosthetics (cochlear implants), for example, are the most successful variety of sensory prosthetics) and deep brain stimulation therapies, while recording interfaces can be used for research applications and to record the activity of speech or motor ...
Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound. [3] [4] [5] The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children.
These same electrodes, or derivations thereof using the same biocompatible electrode materials, are currently used in visual prosthetics laboratories, [8] laboratories studying the neural basis of learning, [9] and motor prosthetics approaches other than the cyberkinetics probes.

In medicine, a prosthesis (pl.: prostheses; from Ancient Greek: πρόσθεσις, romanized: prósthesis, lit. 'addition, application, attachment'), [1] or a prosthetic implant, [2] [3] is an artificial device that replaces a missing body part, which may be lost through physical trauma, disease, or a condition present at birth (congenital disorder).
For example, an implant may be a rod, used to strengthen weak bones. Medical implants are human-made devices, in contrast to a transplant , which is a transplanted biomedical tissue . The surface of implants that contact the body might be made of a biomedical material such as titanium , silicone , or apatite depending on what is the most ...
Nowadays, sensory prosthetic devices, such as visual implants, cochlear implants, auditory midbrain implants, and spinal cord stimulators and also motor prosthetic devices, such as deep brain stimulators, Bion microstimulators, the brain control and sensing interface, and cardiac electro-stimulation devices are widely used.

Neuroprosthetics (also called neural prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses.They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.
