Area of Science:

Neuroscience
Biomedical Engineering
Computational Neuroscience

Background:

Transcranial magnetic stimulation (TMS) studies often use blocked paradigms, limiting trial-by-trial parameter manipulation.
Controlling Magstim stimulators on a trial-by-trial basis is challenging due to command frequency requirements and potential interference with precise stimulus delivery.

Purpose of the Study:

Introduce the MagPy toolbox, a Python software package for comprehensive control of Magstim stimulators.
Enable precise, trial-by-trial manipulation of TMS parameters without compromising temporal accuracy.

Main Methods:

Developed MagPy, a Python software package for serial port control of Magstim stimulators.
Designed a "QuickFire" serial cable for low-latency TMS pulse triggering.
Validated MagPy's control and timing precision through experimental simulations.

Main Results:

MagPy maintained uninterrupted remote control over Magstim stimulators during all simulations.
Stimulus delivery timing remained unaffected by MagPy, with precise duration control.
The QuickFire cable enabled TMS pulse elicitation with sub-millisecond latencies.

Conclusions:

The MagPy toolbox and QuickFire cable provide effective, high-precision control of Magstim stimulators for advanced TMS experiments.
This solution facilitates experiments requiring trial-by-trial parameter adjustments and tight temporal synchronization, such as TMS-fMRI or TMS-EEG studies.
