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.
Unlike other prostheses, infection is a much greater issue for neural implant, due to the sensitivity of the brain; therefore an external power source is not envisagable. Because the brain is also highly heat sensitive, the power and the device itself must not generate too much heat to avoid disrupting brain function.
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.
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." [1]
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]
