The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit operates according to the exact expression of the nonlinearity required by the FitzHugh-Nagumo model of neural activity. This has allowed them to investigate the real-time effect of noise and confirm that a ghost frequency is present, a nonlinear signature that could be useful to develop pitch perception applications.
