Simulation of cross capture.
Vertical scaling factors are indicated next to the appropriate variable. Δt for each simulation is 20 min. A, WTET is delivered to S1 before SLFS is delivered to S2. Illustrated synaptic variables are for S1. The break in the x axis, followed by the traces for PKMs and W between 100 and 101 h, illustrates the permanent transition of PKMs and W. B, WLFS is delivered to S1 followed by a STET to S2. LTD results, but begins to decay after several h, as N and therefore W increase towards baseline with the slow time constant τN.
