In 1952, Hodgkin-Huxley have developed an electronic circuit describing the biophysical nature of a neuron. Acetylcholine field effect transistor (AchFET) has been developed in this paper for detection of Acetylcholine (neurotransmitter) and then the AchFET is used in an electronic circuit to reproduce neuronal signals. AchFET is an enzyme field effect transistor (ENFET) fabricated by immobiliz...
