In a post on www.bci.plus published in July 2022, we took a deep dive into how to use LSL in combination with Brain Products equipment, including our amplifiers, the TriggerBox and other useful accessories. By using hardware triggers with our TriggerBox, you will always benefit from the most accurate timing because your triggers are directly bound to and recorded alongside the EEG data; however, having an extra piece of equipment may not always be ideal for some experimental setups or application fields (for example, MoBI), but LSL provides a great software solution in these cases. Our Technical Product Manager, Dr. Alex Kreilinger, demonstrates how LSL markers can be used as an alternative to hardware triggers and illustrates, with real examples, how you can add such software markers to your experiment from a variety of stimulus presentation software tools.
Examples are provided for a similar paradigm, guiding you through installation, preparation, activation (and deactivation) of both the LSL markers and hardware triggers for E-Prime®, Presentation®, PsychoPy, and Psychtoolbox. We also provide you with helpful tips and tricks along the way so you will be an expert in both hardware and software triggering, by way of LSL, regardless of which stimulus presentation software you are using for your next experiment.
