Connexus® Brain-Computer Interface

Recording individual brain signals that turn thought into action.

Communication is a fundamental human need. The inability to express yourself with family and friends or request basic needs makes living difficult. For people with motor conditions caused by ALS, spinal cord injury, or stroke, speaking or using the computer may be impossible.

Connexus enables motor-impaired people to communicate again and to independently use a computer by translating neural signals into synthesized speech, text, and cursor control.

INTRODUCING CONNEXUS

A category-defining BCI

Paradromics combined advanced neuroscience with medical device expertise to create Connexus, leaping beyond 30 years of brain-computer interface (BCI) research.

Built for long-term medical use, Connexus is the first high-data rate BCI designed to deliver high performance for the user.

  • Communication at natural speeds
  • Replication of complex mouse and keyboard hand actions

ADVANCEDNEUROTECHNOLOGY

Our cortical module packs sophisticated
neurotechnology into

a tiny package that can only be fabricated in the Paradromics' foundry.

CONNEXUS BCI

Cosmetically-invisible cortical module has clear advantages

Proven materials

Built from metals common in medical implants, including a titanium alloy body and platinum-iridium electrodes

Direct access to individual brain signals

With 421 micro electrodes located next to the neurons, patented on-chip processing records massive amounts of data

Longevity

Biocompatible materials and a fully implantable format enable Connexus to last a user’s lifetime

Brain friendly

The Connexus electrodes are miniaturized to smaller than 40 microns, each thinner than a hair

How it works

The Connexus BCI

01

A neurosurgeon places the Connexus BCI system under the skin: cortical module, internal transceiver, and connecting lead. The surgery uses well-developed techniques common in other healthcare applications.

The Connexus DDI system includes the Cortical Module, Internal Transceiver, and the connected lead to transfer a continuous stream of data
How it works

02

The microelectrodes of the cortical module extend just below the brain’s surface to gather rich signals from individual neurons in the motor cortex.

03

This data is sent along a thin, flexible lead to a transceiver in the chest. This disk-shaped transceiver wirelessly transmits data by a secure optical link to a second transceiver worn by the user. The second transceiver powers the system through inductive charging, similar to wireless charging for smartphones.

The data is then sent to a small computer loaded with advanced language models and AI. The software analyzes the user’s brain data to figure out what they intend to say or do and translates into words (text on a screen or synthesized speech) or enables control of digital devices.
