PowerMAG QPS
Quattro-Pulse stimulation – a new patterned rTMS 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 700Hz.
Features
- ultra-high speed bursts with up to 666Hz
- up to 4 pulses in a burst package
- same pulse lengths in all stimulation modes and with all coils
- no power roll-of 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
