These silicon - chip mimics faced the same problems of noise that real neurons face. (discovermagazine.com)
All three neurons are designed to act like real neurons, using the «leaky integrate and fire» model in which stimulus pushes the voltage inside the neuron higher and higher until the neuron fires and the voltage drops back down to its original voltage. (sciencemag.org)
Their model is validated against the coding properties of real neurons by means of their location in what the authors call the «coding space.» (sciencedaily.com)
