There is niche called brain computer interface (BCI) — it consists of electrodes that either penetrate the brain or sit on its surface to provide direct communication to computers.

Such brain implants are useful for patients who are paralyzed due to neurodegenerative disease –amyotrophic lateral sclerosis, stroke and multiple sclerosis.

Elon Musk, as we know, has set up a startup called Neuralink, a brain implant unit. A rival company Synchron also operates in this space. It is roping in patients for clinical trials at 120 centers. Synchron is New York-based company. It received US authorization for preliminary testing in July 2021. It has tested in the US and Australia with no adverse side effects. The aim is to help paralyzed patients type on a computer using devices that translate brain signals.

A larger trial awaits the nod from the US FDA. Neurosurgeons at University of Buffalo and University of Pittsburgh are collaborating on preliminary study. Data is being collected while the brain implant is used.

Successful testing could benefit a significant population.
