Trigger event informations

BeatriceB · October 2018

Dear All,

I am using Cyton and Daisy board with gold cup electrodes. I am doing a neurofeedback study about alpha suppression during the performance of a working memory task. I present my stimuli using psychtoolbox. How do I record\mark event informations (the stimuli that are time-locked to the participant's response and EEG signal modulation while performing the task)? Is there a specific way to do it in Matlab? I would need then to import "event information" into EEGLAB for my analysis...

Let me know please.

Thank you so much for your time, help and patience. And sorry if it was a stupid questions!

Best regards,

Beatrice

Beatrice, hi.

I have not done this myself, but here are some thoughts. Psychtoolbox runs in Matlab. You are presenting your stimuli with Psychtoolbox / Matlab. Therefore you will be able to generate markers in the LSL stream using these methods, by calling the appropriate LSL routines.
