Much research is also being done on the surface chemistry of neural implants in effort to design products which minimize all negative effects that an active implant can have on the brain, and that the body can have on the function of the implant. Another type of neural implant that is being experimented on is prosthetic neuronal memory silicon ...
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.
Recent work shows that the system can form long-term memories in many different behavioral situations. Berger and colleagues hope to eventually use these chips as electronic implants for humans whose brains that suffer from diseases such as Alzheimer's that disrupt neuronal networks.
A typical cortical implant is an implantable microelectrode array, which is a small device through which a neural signal can be received or transmitted. The goal of a cortical implant and neuroprosthetic in general is "to replace neural circuitry in the brain that no longer functions appropriately."
Testing an implant in stroke patients can be particularly challenging, as an individual's brain may be so severely damaged that there isn't sufficient neural signaling to record.
Opie began designing the implant in 2010, through Synchron, a company he founded with Oxley and cardiologist Rahul Sharma. [9] The small implant is an electrode array made of platinum electrodes embedded within a nitinol endovascular stent. The device measures about 5 cm long and a maximum of 8 mm in diameter. [10]
Deep brain stimulation (DBS) is a surgical procedure that implants a neurostimulator and electrodes which sends electrical impulses to specified targets in the brain responsible for movement control.
Neural implants have the potential to increase the quality of life for patients with such disabilities as Alzheimer's, Parkinson's, epilepsy, depression, and migraines. With the complexity of interfaces between a neural implant and brain tissue, adverse reactions such as fibrous tissue encapsulation that hinder the functionality, occur.
