REMINDER

Please note that for this term the room for our weekly Biomed Seminar will change
It will be in room 333 instead of room 321, so we will have more space available (just a little further in the same corridor)

Dear all,

Our next Biomedical Engineering Dpt seminar will be next Wednesday October 20th

Wednesday - October 20th,  at 1 pm

Location: Room  333 Lyman Duff Building (Biomedical Engineering Dpt).

Speaker: Pr. Olivier Coulon, CNRS research Fellow, LSIS Laboratory, I&M Team, ESIL, Marseille, France

Title: Structural analysis of functional MRI data : a surface-based approach

Abstract:
Functional Magnetic Resonance Imaging (fMRI) provides an access to brain function via measurements of changes of the level of oxygenation of hemoglobin. In this talk I will present an alternative to the iconic (voxel-by-voxel) analysis of fMRI data in a multi-subject context. In the most common approach of fMRI group studies, an individual statistical map is built for each subject, that represents the level of brain activity correlated to the experimental paradigm at each location (voxel). All individual maps are then registered to a common space in which a second-level analysis takes place. This second-level analysis aims at detecting activations at the group level, and takes a decision for each voxel, a level at which inter-subject variability makes little sense and inter-subject registration errors have large consequences. Instead, structural analysis relies on object-based representations of individual functional maps. In a multi-subject context, it matches those representations instead of matching directly the maps. Group activation detection is then performed at the structure/object level, where anatomical variability makes more sense and is easier to control. I will present such a structural analysis in a surface-based context, i.e. using representations of functional activity on the cortex surface, as opposed to the volume of acquisition. The advantages of such a method will be presented using synthetic and real data.
