Registration is now open for two free Brain Products Academy webinars

“Introducing LSL with Brain Products”

Sign up for our upcoming Brain Products Academy webinars on June 28th and July 5, 2022 (9:00 AM or 4:00 PM CEST). Dr. David Medine and Dr. Alex Kreilinger will present 2 free webinars introducing LabStreamingLayer (LSL). Get the details of this webinar series here: Introduction to LSL with Brain Products

Part 1: Introduction to the basic purpose, principles and practice of using the LabStreamingLayer (LSL) on June 28, 2022

LabStreamingLayer is a real-time data streaming framework complete with tools for recording and loading data. LSL was created with experimental human psychological/physiological neuro-imaging applications (particularly EEG) in mind. Consequently, LSL is an excellent tool for brain computer interfacing. In particular, LSL generalizes the problem of getting synchronized, real-time data in and out of hardware and computers in an easy, out-of-the-box way.

One of the key features of LSL is its ability to synchronize multiple data and marker streams regardless of data type and sampling rate. Therefore, to use LSL effectively, it is important to understand how this synchronization is achieved and how to fix it when something goes wrong. For this reason, this webinar covers the following topics:

  • 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 on July 5, 2022

Stimulus presentation software solutions for Brain Products and LSL

In Part 2, we demonstrate a selection of established stimulus presentation software solutions. The demonstrations include E-Prime, Presentation, PsychoPy, and PsychToolbox. We will show how they can be used to add events in your EEG data. Further, we will 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, you will receive instructions on how to use provided scripts for running such experiments and scripts for analyzing thereby recorded data. Finally, we’ll discuss and demonstrate potential issues when using LSL and provide tips on verifying timing in general.
