双脉冲磁刺激器(Magstim BiStim²)

Magstim BiStim²

Magstim BiStim² offers the potential to combine two Magstim 200² units to provide fully programmable paired pulse stimulation through a single stimulating coil. The ability to change pulse intervals and to control independently the power level of each Magstim 200² allows for precise sub- and supra-threshold conditioning and test pulses. This is invaluable for the investigation of Inter-Cortical Inhibition and Intra-Cortical Facilitation.

Two inter-pulse spacing options offer maximum controllability:

  • 1ms - 999ms in 1ms increments
  • 1.0ms - 99.9ms in 0.1ms increments

The inter-pulse spacing of the two pulses is adjustable using either stimulator user interface, remote control coil or via externa triggering software offering the user complete flexibility of use.

BiStim² has the added advantage of being able to summate the two single pulses provided by the Magstim stimulators to produce a single high power pulse equal to 113% of a single Magstim 200².
