Dr. Erin Dickie (PhD, Neurological Sciences, McGill University) is a Project
Scientist. Dr. Dickie’s research focus is personalized connectomics, or the
ability to map brain organization at the level of the individual. Individual
mapping of brain function may be a critical first step in the design of
targets for stimulation therapy. Dr. Dickie recently submitted a manuscript
describing her tool for mapping neurodiversity (PINT), and showed that the
brains of those affected by autism and more variable in their organization
that those of typically developing controls. This work suggests that
personalized brain mapping might be a critical first step for future
biomarker discovery. Dr. Dickie also assists with the lab’s data management
and analysis system, and builds automated tools for data analysis. In the
past year, she has developed a new tool for surface-based analyses (ciftify)
that has been publicly available and adopted by international groups.

 

Abstract:

Emerging work from the neuroimaging community shows that everyone’s cerebral
cortex has a unique functionally organisation and that this unique
organisation can be mapped using neuroimaging data at the individual
participant level. To do so, we start with an analytic approach, using the
CIFTI file format, that allows for a more neuroanatomically-faithful
representation of data. An open source set of tools ‘ciftify’ (
<https://edickie.github.io/ciftify> https://edickie.github.io/ciftify) make
this approach more accessible to the greater scientific community. We than
introduce novel methods for incorporating resting-state fMRI data to map the
spatial topography of the cortical surface in individual subjects and
discuss the applications to the study of brain pathologies including Autism
Spectrum Disorder and Schizophrenia. Using the ABIDEI dataset, we found
greater spatial variability in resting state network location in individuals
with ASD with a disrupted developmental trajectory.  Accounting for this
variability decreased the number of hypo-connected regions observed in
individuals with ASD. This phenomenon could have far reaching implications
for how clinical neuroimaging research is analysed and interpreted. 

 

I hope to see you there / J’espère vous voir nombreux.
