MAPS: the micro action potential scanner

A new high-resolution neural probe, the micro action potential scanner (MAPS), is proposed. The MAPS is designed for simultaneous recording from many cells in a single neural network, a challenging task using conventional neural probes. Conjectures are made about the MAPS' potential to record from more single cells from a smaller area than microelectrode arrays due to the MAPS' higher spatial resolution. The MAPS gains its high resolution by its ability to scan an area of neural tissue. Scanning is made possible by the novel use of a p-n junction.
