PROBLEM TO BE SOLVED: To provide a neural recording system capable of suppressing an influence of noise.SOLUTION: First, a neural amplifier amplifies a very small neuron signal. Filters whose gain and bandwidth are program-controllable are connected in series, whose setting is executed on the basis of a notable signal. A buffer provided at each channel pass a filtered output through a multiplexer. Subsequently, an ADC digitalizes the signal at a sampling rate of 40 kS/s for each channel and supplies, to a DCM, the output for data serialization and unique processing execution of a channel identifying multipoint factors.SELECTED DRAWING: Figure 1
