Course objective

This elective will give students a first introduction to "Cognitive
Electrophysiology", in which electrophysiology is used to measure and
understand cognitive functions such as visual perception, attention,
working memory and language in terms of brain processes. The course will
provide students with a rudimentary theoretical and methodological
background in electroencephalography (EEG) and to some extent
magnetoencephalography (MEG), enabling them to better understand and
interpret currently cutting-edge analysis techniques that are
increasingly being applied to EEG, MEG, and other electrophysiological
signals in cognitive neuroscience.
At the end of the course, students:
• Know the historical and theoretical background of cognitive
electrophysiological signals such as EEG: where does EEG come from and
what neural processes does it capture? What are its strengths, what are
its weaknesses?
• Understand the basic steps involved in setting up an EEG experiment
• Have obtained a first hands on introduction to EEG acquisition and
know the steps involved in acquiring EEG
• Are able to perform rudimentary EEG analyses, including pre-processing
and computing an ERP
• Are able to understand and interpret most basic and some advanced EEG
analyses

Course content

• The neurophysiological basis of EEG and MEG: history, relationship
with neural activity, source localization, the inverse problem
• Preprocessing of electrophysiological signals: what is a ‘signal’?
re-referencing, filtering, artifact rejection
• Basic analyses: Event Related Potentials (ERPs), the multiple
comparison problem
• Important classical findings using ERPs in the context of cognitive
functioning: ERP components involved in visual and/or language
processing such as the C1, P1, N2, P3, N400, P600; lateralized
components involved in action selection, attention and memory such as
the LRP, N2Pc, CDA. The functional meaning of ERP components, and how to
set up EEG experiment.
• Rudimentary time-frequency analysis: Time-frequency decomposition
using fourier and wavelets, relationship between ERPs and the
time-frequency domain, total power versus induced power
• Multivariate statistics: brain reading by obtaining classification
accuracy through decoding methodology, train-test analysis approaches,
investigating cortical stability through Generalization Across Time
matrices.
• Building forward encoding models that specify the relationship between
cortical activity and some continuous cognitive variable, allowing one
to predict cognitive contents or cortical activations maps for ‘new’
conditions for which no data exists

Form of tuition

Lectures, computer practicals and lab demos.

Type of assessment

Every lecture starts with a mini-exam.
The final exam consists of 10 open questions.

The final grade consists of:
75% Final exam
15% participation in practicals (percentage finished practicals,
attendance obligatory)
10% Average of the mini-exams that are given at the start of every
lecture
Lecturers and practicals are obligatory. If you miss more than two
practicals, you will not get a grade for the course.
