1. A biological interface system comprising: a sensor comprising a plurality of electrodes for detecting multicellular signals emanating from one or more living cells of a patient; a processing unit configured to receive the multicellular signals from the sensor, process the multicellular signals to produce a processed signal, and transmit the processed signal to a controlled device; the controlled device for receiving the processed signals; a visual display for providing visual images to the patient; and an integrated patient training routine performed to generate one or more system configuration parameters used by the processing unit to produce the processed signal; wherein the integrated patient training routine provides a visual representation of a human figure to the patient on the visual display, the representation including multiple human body movements provided for the patient to imagine the movement; wherein the system is configured to store a set of multicellular signals while the patient imagines the movements.
