A modulation device includes at least one memristive device, and a control block, the modulation device having an equivalent conductance y(t) produced by the at least one memristive device and the control block being configured to receive a clock signal and perform a first modification of the equivalent conductance y(t) upon receipt of each clock signal, receive an input voltage pulse and perform a second modification of the equivalent conductance y(t) upon receipt of each input voltage pulse, the first and second modifications being in opposite directions.

Modulation device and method, artificial synapse comprising said modulation device, short term plasticity method in an artificial neural network comprising said artificial synapse

A method for unsupervised sorting, in real time, of action potentials of biological neurons by a network of artificial neurons including input, intermediate and output layers, the method according to which: the input layer receives an electrical signal measuring an electrical activity of biological neurons, the electrical signal having a variable amplitude as a function of action potentials emitted by the plurality of biological neurons over time; the input layer converts the amplitude of the electrical signal into a train of first spikes; the input layer transmits the train of first spikes to the intermediate layer; the intermediate layer converts the train of first spikes into a train of second spikes; the intermediate layer transmits the train of second spikes to the output layer; as a function of the train of second spikes, the output layer sorts each occurrence of each type of action potential present in the electrical signal.
