Workshop 1, 2019
Advanced EEG Signal Processing: a hands-on introduction to Fourier and Wavelet-based analysis
Date: Wednesday, November 20th, 2019. 9:00 to 17:30
Overview
The EEG signal is often used within the bioinformatics field as it provides a large amount of information on human tasks and underlying neural activities in the brain. In order to successfully and efficiently analyze the acquired EEG signals, a number of analyses can be performed, depending on the scientific objectives and tasks performed. During this workshop, our aim will be to deliver lectures and group-formatted exercises that provide the participants with a comprehensive understanding of the spectral analysis methods Fast Fourier Transformations (FFT) and Wavelet Analysis. Participants will also be briefly guided through a variety of topics such as ERP pre-processing and ocular ICA.
During the group exercises, we will make use of Brain Vision Analyzer 2.0, a user-friendly and visual software toolkit that enables participants to perform a variety of EEG signal analysis. Additionally, we will prepare MATLAB code handouts in order to support participants who prefer working with programming software. Group exercises will be performed in groups of ~ 7 participants, guided by a workshop organiser.
