Rhythms of the Brain

2019-2020

Course Objective

The course "Rhythms of the Brain" is focused on measuring, analyzing and
interpreting the functional role of neuronal
oscillations in humans.

At the end of the course the student should be able to:
1. Explain how the human brain generates scalp
electroencephalographic (EEG) signals, both ongoing oscillations and
event-related potentials (ERPs).
2. Acquire practical experience with EEG (i.e., measure EEG, perform
quantitative and statistical analysis to draw conclusions about the
relation between brain activity and cognition/behavior, and present the
results on a poster).
3. Explain key concepts of complex-systems science that have gained
acceptance in the cognitive and behavioral neurosciences.
4. Apply state-of-the-art complexity-analysis techniques to EEG
data and perceptual/behavioral time series, and
5. …understand how these techniques can be applied in fundamental
science and applied medical fields, e.g., for clinical trials and
personalized medicine.
6. Explain the advanced techniques that estimate brain sources from
the EEG signals, and outline the possibilities and limitations based on
own experiences.
7. Explain the rationale of so-called "integrated biomarkers" based on
machine learning, use
specialized toolboxes to compute them and critically reflect on the pros
and cons of this approach to functionally assess the state of a human
brain based on the rhythms that it generates.

Course Content

Understanding the complexity of the human brain and mind is one of the
greatest scientific challenges of the 21st century. To address these
challenges, researchers increasingly adopt theories and methods used to
study complexity in other natural systems. In this course, we give you a
solid conceptual understanding of "complexity" and tools to study the
complexity of the human brain through quantitative analysis of the brain
rhythms that it generates and the variability in cognitive and
behavioral tasks.
We consider it critical that students gain an in-depth
understanding of the analytical tools in order to properly use and
interpret the outcome of the different analysis techniques. This is
achieved by covering the theory in the lectures followed by tutorials in
the computer rooms. The concepts of "critical dynamics" and power-law
scaling behavior are carefully explained in the context of time-series
analysis tools, generating mechanisms, and functional implications. Key
concepts of complex networks and analytical tools to characterize them
based on M/EEG data are also covered.
Another important component of the course is to teach you how to perform
high-density EEG recordings of spontaneous brain activity during
resting-state conditions and cognitive tasks and to analyze these
signals with classical as well as modern complexity algorithms. You will
work in small groups to record, analyze and present both data on EEG and
its cognitive/behavioral correlates at the end of the course.
Finally, the importance of non-stimulus driven brain activity and
cognition for brain-related disorders such as depression, dementia,
insomnia or attention deficit and hyperarousal disorder is discussed in
the context of normal variation in biomarkers and the associated
challenges in objective diagnosis, prognosis, and treatment selection.
We explain how data-mining and -classification techniques from
artificial intelligence can be used to integrate information from
multiple biomarker algorithms to increase the accuracy of clinically
relevant functional assessments. While the course is focused on
understanding variability in human cognition and behavior in health and
disease, the concepts and tools equally apply to research on common
animal models.
