Figure 3. Burst-Time–Dependent Learning Rule at the Retinogeniculate Synapse.

Percent change in synaptic efficacy evoked by pairings at different latencies between pre- and postsynaptic bursts. The average change for non-overlapping bursts (Figure 2E) is shown as a dashed line. The best symmetric (solid) or asymmetric (dotted) burst-based rules are also shown. The three numbered examples are considered in detail in Figure 4.

t _post, time of the postsynaptic burst; t _pre, time of the presynaptic burst.
