Observing the Brain: Neuroimaging Basics

This lecture covers the basics of neuroimaging, focusing on the main instruments used to study human brains in vivo, such as magnetic resonance imaging (MRI) and electroencephalography (EEG). It delves into the different spatial scales of brain networks, the techniques to build brain network maps, and the functional and structural connectivity of the brain. The lecture also explores the history of network neuroscience, the challenges of defining nodes in the human brain, and the physics behind MRI. Additionally, it discusses the functional connectivity through fMRI and EEG/MEG, as well as brain stimulation techniques like TMS/EEG. The key takeaway emphasizes the importance of understanding the data at different scales and the limitations of connectome mapping.
