Two-cell network with synaptic plasticity in one synapse. a Voltage traces obtained from simulations of the M–L neurons when the A to B synapse is of fixed strength and B to A synapse changes according to the plasticity model (2.3). c The evolution of the plasticity variables r, u, $r_n$, and $u_n$ according to the activity of neuron B. d Voltage traces obtained from simulations of the M–L neurons when the A to B synapse is of fixed strength and B to A synapse changes according to the steady-state plasticity profiles given by (2.4). b &e Network connectivity diagram corresponding to the simulations shown in a &d. The parameter values for the plasticity variables are ${\tau }_1=2$, ${\tau }_2=190$, ${\tau }_3=2$, ${\tau }_4=190$
