Part 1 and Part 2 of our free Brain Products Academy “Introduction to LSL” webinar series are now available. Check out both webinars on the Brain Products Academy Webinar Channel.

Part 1: Introduction to the basic purpose, principles & practice of using LSL

LSL is a real-time data streaming framework complete with tools for recording and loading data. It was created with experimental human psychological/physiological neuro-imaging applications (particularly EEG) in mind. In addition, LSL is by nature an excellent tool for brain computer interfacing. LSL generalizes the problem of getting synchronized, real-time data in and out of hardware and computers in an easy, ready-to-use-out-of-the-box fashion. One of the key features of LSL is its ability to synchronize multiple data and marker streams regardless of data type and sampling rate. Thus, to use LSL effectively it is important to understand how this synchronization is achieved and how to fix it when something goes wrong. This webinar will therefore focus on the following:

  • Basic uses of LSL
  • How to set up an LSL ecosystem
  • How to stream, receive, and record data using LSL
  • Understanding LSL’s built in data synchronization tools
  • Troubleshooting common problems

Part 2: Hardware triggers versus LSL markers: Stimulus presentation software solutions for Brain Products and LSL

In this webinar, we demonstrate a selection of established stimulus presentation software solutions. These include E-Prime, Presentation, PsychoPy, and PsychToolbox. We show how they can be used to add events in your EEG data. Further, we cover differences between these solutions: How easy is it to activate/deactivate hardware triggers?  How to use LSL markers in parallel or as an alternative? In addition, we offer instructions on how to use provided scripts for running such experiments and scripts for analyzing thereby recorded data. Finally, we discuss and demonstrate potential issues when using LSL and  provide tips for how to verify timing in general.
