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 ...
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.

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.
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, four different steps must occur to lift the foot to walk. First, impulses from the brain 's motor center are sent to the foot and leg muscles . Next, the nerve cells in the feet send information, providing feedback to the brain, enabling it to adjust the muscle groups or amount of force required to walk across the ground.
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 ...
A prosthetic arm. Artificial arms and legs, or prosthetics, are intended to restore a degree of normal function to amputees.Mechanical devices that allow amputees to walk again or continue to use two hands have probably been in use since ancient times, [10] the most notable one being the simple peg leg.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
