1. A system for collecting multicellular signals from a central nervous system of a patient and for transmitting processed signals to a controlled device, comprising: a sensor comprising a plurality of electrodes configured to detect the multicellular signals; a processing unit configured to receive the multicellular signals from the sensor, process the multicellular signals to produce processed signals, and transmit the processed signals to the controlled device; and the controlled device for receiving the processed signals, wherein the processing unit creates and records a neural signature representing a reproducible derivative of one or more multicellular signals detected, and wherein a current derivative of the multicellular signals is compared to the recorded neural signature as a check for system compatibility.
