ENU Workshop 2018


  • The annual ENU meeting was held on April 29-30, 2018, and focused on decoding and encoding approaches in (f)MRI anaysis:

About the workshop:

As the field of MRI research keeps growing rapidly, so do the techniques and methods researchers use to answer their next research question. Developments both in data acquisition and in offline analysis algorithms have increased our ability to extract information from brain activation patterns dramatically. Terms such as decoding and encoding, multivariate pattern analysis (MVPA), representational similarity analysis (RSA), multi-dimensional scaling (MDS), and pattern component modeling (PCM) are being used to map the brain's organizational and functional principles. All of these methods (and others) hold potential for new discoveries, but using them appropriately may not be straightforward. The workshop will give state-of-the art view of some of these computational tools, the motivation for using them, as well as their advantages & caveats. Lectures will be given by two of the most prominent figures in the field, Dr. Jonathan Winawer (NYU) & Dr. Joern Diedrichsen (University of Western Ontario).


About the lecturers:

Jonathan Winawer    

 slides I    |   Slides II   |   tutorial code

Prof. Winawer has completed his PhD in brain and cognitive Sciences at MIT, titled “Common mechanisms for the representation of real, imagined, and implied visual motion”. He did his post doctorate at Brian Wandell’s lab in Stanford, where he employed various models to study the properties of the visual system. He is currently an assistant professor at NYU psychology & natural science department, where he continues to research how visual stimuli are encoded in the visual pathways, using various sophisticated analysis and modeling methods.

Joern Diedrichsen

slides   |   tutorial code

Prof. Diedrichsen completed his PhD at Berkeley. He then did his post doctorate in Reza Shadmehr’s lab at Johns Hopkins university, where he studied reach adaptation using fMRI and statistical learning. His group uses imaging methods to understand how the human brain learns and executes movements, with a strong emphasis on computational models. In recent years, he became a leading voice in the ongoing debate about the usage of decoding and encoding methods for understanding fMRI activations. He currently holds the Western Research Chair for Motor Control and Computational Neuroscience at the Brain and Mind Institute, Department for Computer Science, University of Western Ontario


ENU Day 2017

The 1st scientific ENU day was hosted on March 29, 2017, at ELSC. The conference focused on our community's scientific work, allowing scientists to share recent professional insights and experiences. It included oral & poster sessions from different labs, as well as a guest lecture by Prof. Miki Lustig from U Berkeley.

The 3rd ENU Annual Workshop on  Nov 25-26, 2015

 In 2015 we hosted the BrainVoyager team for a 2-days course on various fMRI analysis tools. 

We had afternoon scientific session with Prof. Rainer Goebel, Maastrich University and Prof. Nikolaus Weiskopf from UCL.

First talk at 17:00 with Rainer Goebel, Maastrich University, Netherlands

On the topic of
"Revealing Mesoscopic Coding Principles in the Human Brain with Ultra-High Magnetic Field fMRI"

Abstract: Ultra-high magnetic field (UHF) scanners (7 Tesla and higher) provide the possibility to study the functional organisation of the human brain at the level of cortical columns and cortical layers. First progress in this direction has been achieved by revealing individual topographic columnar-level orientation maps in human primary visual cortex, frequency maps in primary auditory cortex and axis-of-motion maps in area hMT/V5. In an extension to multi-sensory stimuli, we revealed that increased spatial resolution at 7 Tesla leads to a better segregation of unimodal and heteromodal voxels in the superior temporal gyrus and planum temporale. More recently, also cognitive tasks have been investigated at the mesoscopic level. We, for example, relate the content of perception during perceptual switches of ambiguous motion stimuli (Plaids) to dynamic activation changes in direction-selective columns in area hMT/V5. Furthermore, we reveal that top-down effects in visual tasks operate on supragranular cortical layers in area V1, which is compatible with predictive coding theories. The presented studies demonstrate that the achievable mesoscopic level of investigation (columns and layers) offered by UHF fMRI allows to map columnar-level features within specialized brain areas as well as revealing layer-specific functional bottom-up and top-down connectivity. Furthermore, mesoscopic fMRI establishes an important bridge to invasive animal research, especially to optical imaging and electrical neuronal population recordings.

Second talk at 18:00 with Nikolaus Weiskopf, University College London, UK and Max Planck Institute for Human Cognitive and Brain Sciences, Leipzig, Germany

On the topic of

"Towards In-Vivo Histology using MRI" 

  Abstract: Understanding the normal and diseased human brain crucially depends on reliable knowledge of its anatomical microstructure and functional micro-organization (e.g., cortical layers and columns of 200-1000µm dimension). Even small changes in this microstructure can cause debilitating diseases. Until now, the microstructure can only be reliably determined using invasive methods, e.g., ex-vivo histology. This limits neuroscience, clinical research and diagnosis.I will discuss how an interdisciplinary approach developing novel MRI acquisition methods, image processing methods and integrated biophysical models aims to achieve quantitative histological measures of brain tissue, leading to the emerging field of in vivo histology using MRI. In particular, I will present recent methodological advances in quantitative MRI and related biophysical modelling. Examples will include: characterization of cortical myelination and its relation to function; mapping of the axonal g-ratio in a population; changes due to spinal cord injury; age-related brain changes. The presentation will conclude with an outlook on future developments, applications and the potential impact of in-vivo histology using MRI.
