The spike response model (SRM) is a spiking neuron model in which spikes are generated by either a deterministic or a stochastic threshold process. In the SRM, the membrane voltage V is described as a linear sum of the postsynaptic potentials (PSPs) caused by spike arrivals to which the effects of … See more In the SRM, at each moment in time t, a spike can be generated stochastically with instantaneous stochastic intensity or 'escape function' $${\displaystyle \rho (t)=f(V(t)-\vartheta (t))}$$ See more The Spike Response Model has been introduced in a series of papers between 1991 and 2000. The name Spike Response Model probably … See more • Spike Response Model, Chapter 6.4 of the textbook Neuronal Dynamics • 'soft threshold' and escape noise, Chapter 9 of the textbook Neuronal Dynamics See more For simulations, the SRM is usually implemented in discrete time. In time step $${\displaystyle t_{n}}$$ of duration $${\displaystyle \Delta t}$$, a spike is generated with … See more Theory of computation with pulsed neural networks Since the formulation as SRM provides an explicit expression for the membrane voltage (without the detour via a differential equations), SRMs have been the dominant … See more WebJul 29, 2024 · The Spike Response Model (SRM) is a neuron model that describes the input-output relation of biological neurons.
