Neuralink Rival Paradromics Tests Brain Implant in First Human

Paradromics Inc., a brain implant company and rival to Elon Musk’s Neuralink, tested its device in its first human patient last month.

Neurosurgeon Matthew Willsey put a chip smaller than a penny on the patient’s brain while the person was undergoing surgery for epilepsy and left it there for 10 to 15 minutes. Needles half the diameter of a human hair poked into the brain tissue, aiming to pick up electrical signals from individual neurons.
