Brain-chip technology is quickly accelerating. In one of the latest advancements, researchers have designed a new chip that uses larger groups of neurons and less power to detect when a user wants to initiate a given behavior—for example, reaching for an object. The new approach, if it translates into humans, could theoretically provide users with more autonomy in initiating movement control.

Implanted systems known as intracortical brain-computer interfaces (iBCIs) are a game changer for many people with paralysis, providing them with a means to regain some movement control. iBCIs work by inserting electrode arrays into the brain to record neural activity. Because our neurons naturally communicate with one another using electric pulses, these brain chips are able to detect the electrical signals. Click here to get access to the full article.
