Brain Connectivity: Structure & Function
Weekend Course

ORGANIZERS: Fernando Calamante, Jongho Lee

Sunday, 12 May 2019
Room 710B  13:30 - 16:30 Moderators:  Masaki Fukunaga, Patricia Figueiredo

Skill Level: Intermediate

Session Number: WE-24

In this session, functional and structural brain connectivity (measured by resting state fMRI and diffusion MRI, respectively) will be introduced, and the link between these two connectivity types will be discussed.

Target Audience
This course is designed for basic scientists, clinicians and technologists, who would like to learn about functional and structural connectivity of the brain.

Educational Objectives
As a result of attending this course, participants should be able to:
- Describe basic concepts of structural and functional connectivity in MRI;
- Explain data processing steps for connectomics measurements; and
- Recognize the link between structure and functional connections in the brain.


  How the Brain Is Connected
David Van Essen
Recent studies of long-distance connections in the cerebral cortex reveal that they are remarkably complex, but major insights have been learned using anatomical tracers in monkeys and mice and noninvasive neuroimaging in humans and monkeys.

  Introduction to Functional Connectivity
Zhongming Liu
This talk will serve as an introduction to functional connectivity. The primary focus is on spontaneous brain activity observed with functional magnetic resonance imaging. In this talk, I will cover the origins of resting state fMRI signals, analysis methods to map large-scale functional brain networks based on fMRI (or MEG/EEG), dynamics of functional connectivity, variation of functional connectivity across brain states, diseases, or individuals, as well as some recent work of using deep learning to map or analyze functional connectivity.  

  Introduction to Structural Connectivity
Maxime Descoteaux
Introductory course for people seeking to learn about the fundamental of structural connectivity and building the “connectome” using diffusion MRI tractography.

  Linking Structural & Functional Connectivity: Methods & Modeling
Richard Betzel
The human brain can be modeled as a set of white-matter fibers (structural connectivity; SC) that constrain inter-regional interactions and shape the correlation structure of brain activity (functional connectivity; FC). Though SC and FC capture distinct connectional modes, they can both be modeled as networks. Understanding their relationship to one another is critical for if we wish to deepen our knowledge of the role networks place in cognition, health, and development. In this talk I will review current approaches for linking SC with FC, emphasizing that there exists a spectrum of approaches, each suited for answering specific research questions.
