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 simultaneously and stimulate neural activity with high precision.
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.
¶ History and Development
Paradromics was founded in 2015 by a team of neuroscientists and engineers with backgrounds in neural interface technology, semiconductor design, and medical device development.
