A new patterned repetitive transcranial magnetic stimulation (rTMS) protocol, quadri-pulse stimulation (QPS), can produce a broad range of motor cortical plasticity ranging from MEP suppression to MEP facilitation depending on the interval of the pulses within a burst. In addition to inducing lasting cortical plastic changes, QPS can also be used to evaluate priming effects: when used as a priming stimulation, which does not induce an LTP- or LTD-like phenomena itself, it can nevertheless change the threshold for LTP- or LTD-like plasticity caused by a consecutive stimulation. This enables us to examine metaplasticity theory in more details in humans.
