Questions

• What is the Fourier spectrum?

• What is the Fourier transform?

• How do these concepts generalize to graphs, such as the human connectome?

Objectives

• Get familiar with basic graph signal processing (GSP).

• Get an intuition on how brain function and structure can be studied with GSP.

Link / Slides to theory and exercises.

Key Points

• Oscillations are just Fourier modes of a ring graph.

• Connectome harmonics are just Fourier modes of a connectome graph.
