Facebook said on Monday that it had bought CTRL-labs, a start-up in New York that is exploring ways for people to communicate with computers using brain signals.

Andrew Bosworth, Facebook’s vice president for augmented and virtual reality, announced the deal in a Facebook post.

CTRL-labs will join the Facebook Reality Labs team, Mr. Bosworth said, without giving any financial details.

Facebook said it intended to use the neural interface technology of CTRL-labs in developing a wristband that connects to other devices intuitively.
