Numbers preceded by the symbol> are the longest durations tested. No after discharge or spread of
excitation has been encountered v,rith single trains of rTMS at these combinations of stimulus frequency
and intensity.
Magnetic Field:
Pulse Characteristics:
The magnetic field produced by the Magstim Rapid
2
depends on the type
of coil connected. In the case of the Double 70mm Coil supplied with the
system, the field output is l.2T at the smface of the coil.
