Channel count and synapses

Channel count is a measure of the number of neurons or brain regions a brain-computer interface (BCI) is able to stimulate and/or record at the same time. It is an effective measure of the capabilities of BCI devices because it represents the upper limit of information flow between brain and device.

Traditionally, BCIs are judged on the number (or “channels”) of electrodes, but neurons can be packed orders of magnitude more densely than electrodes and each one forms a multitude of connections once it reaches into the brain. Using our technology, a million embedded neurons could form a billion synapses with the brain which would provide unparalleled insights into the structure and communication patterns of our brains.
