Patent ID: 7187968

Claim:
A neural spike detection system, comprising: (a) a signal receiver operable to receive a plurality of neural signals comprising a neural spike and wherein the signal receiver comprises a plurality of neural sensors for detecting the neural signals from neurons; (b) a neural spike detector adapted to communicate with the signal receiver and detect the neural spike in the plurality of neural signals; (c) a transmitter in communication with the neural spike detector and operable to transmit an information signal when a neural spike is detected; (d) a multiplexer comprising an output and one or more inputs connected to the neural sensors for selecting a neural signal as a reference signal as the output; and (e) a plurality of operational amplifiers having first and second inputs, wherein the neural sensors are connected to the first inputs of the operational amplifiers and the second inputs are connected to the output of the multiplexer for providing a difference signal between the neural signals of the neural sensors and the reference signal.
