The main purpose is to introduce attendees to the practicalities of doing MEG research with a specific focus on pipelines for group level analysis and statistics
The main purpose of the course was to provide the students with a solid understanding of the tools available to analyze brain activity data measured with magnetoencephalography (MEG) and electroencephalography (EEG). The students should develop the ability to critically review results provided by different methods, to select the most adequate tools and experimental designs to answer different questions and to compare their relative advantages.
