" ... Place fields could be produced in vivo in a single trial by potentiation of input that arrived seconds before and after complex spiking.The potentiated synaptic input was not initially coincident with action potentials or depolarization.This rule, named behavioral timescale synaptic plasticity, abruptly modifies inputs that were neither causal nor close in time to postsynaptic activation. ...", " ... To determine if the above plasticity rule could be observed under more realistic model conditions, we constructed and optimized a biophysically detailed model and attempted to fully account for the experimental data. ...
