Abstract Circuitry is provided that closely emulates biological neural responses. Two astable multivibrator circuits (AMCs), each including a negative differential resistance device, are coupled in series-circuit relationship. Each AMC is characterized by a distinct voltage-dependant time constant. The circuitry exhibits oscillations in electrical current when subjected to a voltage equal to or greater than a threshold value. Various oscillating waveforms can be produced in accordance with voltages applied to the circuitry.
