For many EEG studies, adding information about events (such as stimulus onsets, and responses) to the EEG recording is crucial. A powerful approach to record events as they occur is by using hardware triggers. In this free Brain Products Academy webinar “Design effective trigger codes for your EEG study” you’ll learn how to enhance the accuracy and reliability of your EEG research by mastering the use of  hardware triggers for multi-event recordings. In this expert-led webinar, you’ll learn a structured approach to integrating event markers—such as stimulus onsets and participant responses—into your EEG data using BrainVision Recorder software.

Join us on October 23, 2025!

For your convenience we are offering two different time slots for this webinar on Thursday, October 23, 2025: 10:00 to 11:00 AM and from 4:00 to 5:00 PM.

The content of each time slot will be the same. All times refer to Central European Summer Time (CEST) zone. Please check your time difference to CEST before signing up for one of the time slots.

Attendance to this webinar is free of charge, so make sure one of the available spots is yours!

Why accurate event recording matters in EEG studies

Adding one event to your EEG data with a trigger can be easy. But capturing all relevant events — across dozens or even hundreds per session — can appear challenging. Events may vary in type, originate from multiple devices, and follow different orderings between sessions and across participants. Inaccurate, ambiguous and incomplete event logging can lead to costly errors in data analysis.

What you’ll learn in this webinar

Whether you’re new to EEG or a seasoned researcher, this session will equip you with essential skills to streamline your study setup and improve data integrity. We will show you how recording ALL relevant events accurately can be made easy by designing suitable trigger codes. Topics include:

• Understanding events, event markers, and hardware triggers
• How events are coded into triggers, and triggers decoded into event markers
• Designing effective trigger codes for complex studies

Hands-on training: Tools and techniques

During the hands-on session you’ll gain practical experience with:

• Creating a trigger plan tailored to your study
• Applying the one-to-one criterion for selecting trigger codes
• Using the trigger2marker tool to optimize BrainVision Recorder settings

Maximize your learning

To prepare for the webinar you can:

• Read our Support Article: How to Design Trigger Codes to Obtain Accurate Markers
• Download the trigger2marker tool (compatible with MATLAB R2018a and later)
