Movements of a computer cursor (shown as a blue line) controlled by a brain-computer interface

Fully implantable and programmable spike-based codecs for neuroprosthetics

Image shows the continuous cursor traces controlled by a brain-computer interface in a “center-out-and-back task” using eight targets arranged in a circle. Neural activity is recorded from 192 channels distributed across two microelectrode arrays implanted in the premotor and primary cortex. Data are decoded in real time to control the cursor.
