| Abstract: | An amplifier system for neural electrode is designed and used in the monitoring of the brain neural region during surgery process. The system can produce neuroid electric signals to stimulate muscle, at the same time take corresponding EMG signals for analysis. It is composed of stimulation generator, pre-amplifier, band-pass frequency selection network, buffer amplifiers, signal display circuit, etc. The system basically uses analogue circuits, and the overall amplification gain reaches 960 to 10,000. |
