Overview

This is the homepage for the course Mapping the Connectivity of the Human Brain which will occur July 28 - 31 at the Pontifícia Universidade Católica do Rio Grande do Sul, in Porto Alegre, Brazil. Lectures for the course are scheduled for 17:00 to 20:00 each evening and will be held in room 302 Bloco B of the School of Engineering building (building number 30). Electrical engineering students at PUCRS who are enrolled in 0407-03: Instrumentação Biomédica e Imagens Médicas will receive 1 credit hour for completing this course. This course will be taught exclusively in English.

Instructors:

  • Cameron Craddock, PhD - Research Scientist VI, Nathan S. Kline Institute for Psychiatric Research and Director of Imaging, Child Mind Institute, New York, NY
  • Alexandre Franco, PhD - Associate Professor at Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS) and Coordinator of Research in Neuroinformatics and Image Post-processing at the Brain Institute of Rio Grande do Sul (InsCer)

Background

Mapping the human connectome is an important next step in neuroscience that promises to transform our understanding of the brain (Craddock et al. 2013). The connectome is a complete map of neural connections in the brain and consists of distinct brain regions, their anatomical connections, and the functional interactions. Among the techniques that can be used for measuring the connectome, magnetic resonance imaging (MRI) is dominant, due to its widespread availability, safety, and spatial resolution. Anatomical connections between brain regions are commonly inferred from diffusion-weighted MRI (dMRI) and their functional interactions are inferred from functional MRI (fMRI). Once the data is collected a variety of analysis methods can be employed extract connectivity information (Varoquaux and Craddock, 2013) and to link variability in these connections to intra-individual variation in phenotypic variables (Kelly et al. 2011; Castellanos et al. 2013).

This course will provide an in-depth review of the neuroimaging and analytical methods for mapping the human connectome. It will begin with an overview of the physics behind MRI, dMRI, and fMRI, and the preprocessing techniques that are required to make the data comparable across observations. It will then cover the mathematical techniques for inferring functional and structural connectivity from the data, and for comparing this data across individuals. This will be performed in a mathematical framework that treats the connectome as a graph, in which nodes represent brain regions, and edges between nodes represent functional and structural connections. Advanced topics will be covered such as pattern based classification approaches, as well as multi-modal techniques that integrate information from function and structure. Each lecture will end with laboratory exercises aimed translating the covered information into practical skills.
