Jan 29 (Reuters) - The first human patient has received an implant from brain-chip startup Neuralink on Sunday and is recovering well, the company's billionaire founder Elon Musk said.

"Initial results show promising neuron spike detection," Musk said in a post on social media platform X on Monday.

Spikes are activity by neurons, which the National Institute of Health describes as cells that use electrical and chemical signals to send information around the brain and to the body.

The U.S. Food and Drug Administration had given the company clearance last year to conduct its first trial to test its implant on humans. In September, Neuralink said it received approval for recruitment for the human trial for paralysis patients.
