This is the new MicroTesla low-intensity rTMS Subthreshold Magnetic Feedback Stimulator for the Atlantis. It provides pulsed stimulation from 0 to 400 Hz, and sinusoidal stimulation from 20 to 4000 Hz. The present design uses an exclusive rectilinear spiral coil design, and produces a field strength above 100 milliGauss. This is approximately the same as the strength of the field emitted by a pair of earbuds, hence can designated as “subthreshold audio.” The MicroTesla builds on our established StimFlash technology, providing a wide range of EEG-controlled as well as standard free-running protocols. The Session Wizard can be used to control stimulation. Protocols such as selective stimulation based on EEG component amplitude, as well as dominant frequency with offset designs are possible. Sequences of specified frequencies at specified times, in sequences, can be defined. Up to 2 different pulse frequencies, and up to 2 different sinewave frequencies, with up to 8 “paddles,” can be used. More details will be shown at ISNR in Orlando.
