Current brain implants are made from a variety of materials such as tungsten, silicon, platinum-iridium, or even stainless steel. Future brain implants may make use of more exotic materials such as nanoscale carbon fibers , and polycarbonate urethane. Nearly all implants require open brain surgery, but, in 2019, a company called Synchron was ...
Its direct effect on the physiology of brain cells and neurotransmitters is currently debated, but by sending high-frequency electrical impulses into specific areas of the brain, it can mitigate symptoms [89] and directly diminish the side effects induced by PD medications, [90] allowing a decrease in medications, or making a medication regimen ...
Firstly, non-auditory side-effects, such as vertigo, limit the overall number of electrodes that can deliver useful frequency information. Electrodes found to cause one of these side-effects are deactivated, resulting in fewer signals reaching the brain. In addition, the brainstem is unable to offer the same tonotopic range as the cochlea.

That company began an in-human clinical study last year. In the Neuralink video, Arbaugh talks about the process he underwent to train on the device after doctors implanted it in January.
At age 63, Mark’s diagnosis was official: He had ALS, a disease with which most people are only expected to live three to five years after symptoms develop. “It was a hard pill to swallow ...
The ArgusTM 16 retinal implant is an intraocular retinal prosthesis utilizing video processing technologies. Regarding to the visual cortex stimulation, Brindley, and Dobelle were the first ones who did the experiments and demonstrated that by stimulating the top side of the visual cortex most of the electrodes can produce visual percept.

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 ...
