Paradromics

Overview

Overview

Paradromics is a brain-computer interface (BCI) company developing high-bandwidth, implantable neural interfaces designed to restore communication for individuals with paralysis and neurological conditions. Founded in 2015 and headquartered in San Jose, California, Paradromics aims to create bidirectional brain-machine interfaces that can record from thousands of [neurons](/entities/neurons) simultaneously and stimulate neural activity with high precision["@paradromics"].

The company has emerged as a leading contender in the race to develop clinically viable, high-bandwidth neural interfaces, with a focus on helping patients with severe motor impairments regain the ability to communicate and interact with the world around them.
