Figures & data
Figure 1. Schematic representation of Model I. Arrows denote possible transitions in the presence of an LTP signal (, left panel) and of an LTD signal (
, right panel). Corresponding transition probabilities are indicated. In each panel, the left (resp. right) column corresponds to the
(resp.
) state. The model studied in this work is actually infinitely deep (after Ref [Citation82]).

Figure 3. An integrative figure showing the predictive model (upper panel) and sharp-electrode electrophysiology recordings of a VD4/LPeD1 synaptic pair (two lower panels). While 3 action potentials triggered during tetanic stimulation are insufficient to result in potentiation of a subsequent excitatory postsynaptic potential (EPSP) in the LPeD1 neuron, 11 action potentials elicited during tetanic stimulation result in a potentiated response, as predicted by the model (after Ref [Citation89]).
