Quattro-Pulse Stimulation - A New Pulse Pattern for Inducing LTP/LTD-like Plasticity

A new technology platform enables the combination of ultra-fast QPS (Quattro-Pulse Stimulation) and online TMS-EEG in one device for the first time. This QPS device can be driven on a standard 1-phase power supply and can apply biphasic Quadri-Pulses, Theta Bursts and rTMS.

The selectable burst sequencing allow ultra-high frequency bursts with up to 667 Hz.


  • ultra-high speed bursts with up to 667 Hz

  • up to 4 pulses in a burst package

  • same pulse lengths in all stimulation modes and with all coils

  • no intensity roll-off within the bursts

  • biphasic rTMS, Theta Bursts and QPS protocols within one device

  • online-EEG feasible

  • 1-phase standard power supply

  • ISI [ms] 1.5, 5, 50

  • IBI [ms] 200, 1000, 5000
