An electronic circuit, imitating spiking trains from real neurons, is described. The electronic neuron is a Wien-bridge based circuit with a super-linear spike mechanism. Numerical simulations using ELECTRONICS WORKBENCH and MATHEMATICA software, also hardware experiments have been performed. The characteristics of the spikes are the following: spike height is 100 mV, spike widht is 1 ms, and interspike interval is 100 ms.
