Impact of perturbations on the neuron response
International audience; We propose an overview of the effects of deterministic and stochastic perturbations on the response of a neuron. Our study is based on numerical simulations and experiments with an elementary neural circuit. We use different excitations to highlight various phenomena such as Mode locking, Vibrational Resonance, Ghost Stochastic Resonance... We close the study with a lattice of coupled circuit.
Dynamics of a charge transfer through a memristor between two initially charged cells
A charge-controlled memristor model, with the memristive expression M(q) defined as the ratio between the voltage through the memristor and the current flowing into it, is used in the quantitative study of the charge transfer between two cells initially charged with known voltages. Calling q0 the total charge having flown into the memristor since its first use illustrating the memory feature of this component-, we show that the derivative of M(q) versus q must be a continuous function of q, leading us to improve the expression for M(q). Then, the dynamics of this charge transfer, as well as the time evolution of the voltages of both cells, is analyzed analytically and confirmed by numerical…
