MRS: Magnetic Resonance Studies

Principal Investigator: Dr Douglas Arnold, MD
Publications: Google Scholar

Dr. Douglas Arnold is a neurologist with special expertise in MRI. His personal research interests are centered on the use of advanced neuro-imaging techniques to assess the pathological evolution of multiple sclerosis and Alzheimer's disease and to quantify the effects of therapy on these diseases.

Dr. Arnold's MRS Lab uses conventional Magnetic Resonance Imaging (MRI), Magnetic Resonance Spectroscopy (MRS) and other advanced imaging techniques such as Magnetization Transfer Imaging (MTI) to gain a better understanding of the nature, evolution, and response to therapy of neurological disorders -- particularly multiple sclerosis (MS). Increasingly, the laboratory is focusing on the development and use of advanced image processing of MRI data in order to probe more deeply into the pathogenesis of disease and how this is affected by therapeutic interventions.

neuroSPEED: Neural Dynamics of Brain Systems

Principal Investigator: Dr Sylvain Baillet
Publications: PubMed, Google Scholar, Nature Neuroscience, Neuron and PNAS.

For more information on the current lab members, collaborations, publications, projects, please visit our lab website and our facebook page.

Our broad objective is to comprehend the mechanisms of large-scale brain rhythms (a.k.a. oscillatory neural dynamics): how they enable functions and behaviour by shaping communication in brain networks, and how the earliest detection of their alterations in disease can contribute to improved healthcare prevention and interventions. To achieve this goal, our group has strong expertise in imaging methods and experimental neuroscience, complemented with collaborations in computational and disease models, neuromodulation techniques, and translational arms to the clinic and industry.

Our rationale is that so far, the ubiquitous polyrhythmic activity of the brain has been approached empirically, with underlying mechanisms that remain not understood. This hinders our comprehension of how 1) perception, behavior and consciousness emerge from distributed brain network activity, and 2) the pathophysiology of brain and mental-health disorders affect large-scale neural communication.

Our vision is that these difficult questions require a principled, mechanistic approach: We need to understand how basic physiological factors of neural integrity and function shape the dynamical structure of oscillatory brain rhythms, manifesting interdependence and coupling across multiple frequencies. These phenomena represent a deep source of uncharted markers of neural integrity, excitability, activity and connectivity.

To address our scientific questions, we develop innovative approaches in structural and time-resolved functional neuroimaging. Our preferred technique is electromagnetic imaging with MEG, complemented with other modalities such as magnetic resonance imaging (MRI), basic electrophysiology and neurostimulation techniques.

Our network of collaborators brings together multidisciplinary expertise in: computational models in biology (François, McGill Physics), rodent e-phys (Avoli, de Villers-Sidani, MNI; Williams, Douglas), congenital amusia (Peretz, U of Montreal), epilepsy (Dudley, Montreal Children's Hospital), Alzheimer disease (Breitner, Gauthier, Rosa-Neto, Villeneuve, Williams, McGill/Douglas Institute; Dang-Vu, Concordia University), auditory perception and cognition (Zatorre, MNI), autism & schizophrenia (Jacquemont, U of Montreal; Forgeot d'Arc, Rivière-des-Prairies), ADHD (Brisebois, Szabo; College Montmorency), motor & decision systems (Kalaska, U of Montreal), nanoprobes (Kinsella, McGill/Bioengineering), multimodal imaging (Boudrias, Hoge, Mitsis, McGill), software developments (Leahy, USC; Mosher, U Texas; Hämälainen, Harvard Medical School).

Our lab also provides continuous support and expertise to investigators interested in using MEG for their cognitive and clinical neuroscience research. The MEG core unit at McGill’s Montreal Neurological Institute is part of the McConnell Brain Imaging Centre, and is an open platform for academic researchers and industrial partners.

We are funded by (inter)national public – including CIHR, NSERC, SSHRC, NIH, Brain Canada, Compute Canada, CFI – and private sources (gross total obtained: $30M; 21 presently active grants).

We are advocates of open science, as a vector of research productivity and reproducibility: in 2014-15, our group drove a Quebec Bioimaging Network strategic initiative for open data (the Open MEG Archive), and we host with RO1 NIH support since 2009, the international developments of Brainstorm, a widely used open-source software application for multimodal functional brain imaging (approaching 20,000 registered users).

Bzdok Lab

Principal Investigator: Dr Danilo Bzdok
Publications: PubMed, Google Scholar

For more information on the current lab members, collaborations, publications, projects, please visit the lab website.

There is now increasing momentum in data sharing, open access, and data collection consortia that build richly annotated "big data" repositories for brain and behavior. This unprecedented data setting creates a rapidly growing potential to provide principled answers to human brain organization and its disturbances in brain disease. Dr. Bzdok will take the opportunity to explore, formalize, and predict brain phenotypes of hidden population variation by capitalising on heterogeneous data sources to tackle open questions in systems neuroscience in a way that also paves new ways for precision medicine in brain health.

One of the least expected discoveries that emerged from imaging neuroscience is the "default network". This macroscopical brain network in the recently evolved association cortex probably has a highest metabolic consumption and features the perhaps highest neuronal baseline activity. Functional processing in this network is associated with a diversity of human-defining psychological processes: complex social cognition, such as perspective-taking, language and moral judgment, as well as the imagination of events and places in future and past. At the same time, the default network has been linked to a range of neurodegenerative and psychiatric disorders, including dementia and schizophrenia. Despite its significance for human intelligence, the physiological purpose of this network remains essentially unknown.

His research group is dedicated to such interdisciplinary challenges in a domain-agnostic approach (especially high- but also low-level cognitive processes) leveraging several recently emerged population datasets (such as UK Biobank, HCP, CamCAN, ABCD) across levels of observation (brain structure and function, consequences from brain lesion, or common-variant genetics) using a broad toolkit of bioinformatic methods (machine-learning, high-dimensional statistics, and probabilistic Bayesian hierarchical modeling).

The Neuro Imaging and Surgical Technologies Laboratory develops computer vision image processing algorithms for analysis of medical images that are focused on registration and segmentation. These techniques are applied to different research projects that include image guided neurosurgery and disease diagnosis, prognosis and quantification for diseases such as multiple sclerosis, epilepsy, schizophrenia and degenerative diseases such as Alzheimer’s dementia.

In the Neuro Imaging and Surgical Technologies Lab of the Brain Imaging Centre of the Montreal Neurological Institute, our team develops computerized image processing techniques such as non-linear image registration, model-based segmentation and appearance-based segmentation to automatically identify, quantify and characterize structures within the human brain. These techniques are applied to large databases of magnetic resonance (MR), computed tomography (CT) and ultrasound (US) data from normal subjects to quantify anatomical variability and to characterize the morphological changes associated disease. The data derived can be used for diagnosis and prognosis and to help study natural history of disease and to improve understanding of disease pathology. In image-guided neurosurgery (IGNS), these techniques provide the surgeon with computerized tools to assist in integrating and interpreting anatomical, functional and vascular imaging data, permitting the effective planning and execution of minimally invasive neurosurgical procedures. Our research has been supported by grants from NSERC, CIHR, FQRNT, CFI, NIH and FRSQ.

Our aim is to produce and promote open and reproducible neuroimaging research, with a focus on neuroimaging data science and neuroinformatics. ORIGAMI stands for Open & Reproducible Imaging Genetics and Applied Machine Intelligence.

Our laboratory research program has two main axes. Fist, in order to better understand brain systems and their relation to brain pathologies, we are developing methods and tools to best analyse neuroimaging and genetics data in relation to omics, demographic, behavioural or clinical variables using large databases (e.g., the UK Biobank). Second, in relation with this first goal, we work to produce or foster more reproducible and replicable science in the field of neuroimaging genetics, and more generally in the life sciences. To this end, we use open science principles, and study how research is performed and published in our domain.

We also participate in the construction of tools and infrastructures to more easily disseminate, document, and harmonize datasets and generate re-usable pipelines and analysis methods. We exchange ideas and work with our colleagues in the McConnell Brain Imaging Centre and the Ludmer Centre for Neuroinformatics & Mental Health. We are grateful for funding from Canadian Open Neuroscience Platform (CONP), the National Institutes of Health (NIH), and Healthy Brains for Health Lives (HBHL).

Visual Systems Neuroscience & Brain Imaging Signals

Principal Investigator: Dr Amir Shmuel
Publications: PubMed, Google Scholar

For more information on the current members, collaborations, publications, projects, please visit the lab website.

The research in our laboratory is focused on two goals. The first is to understand the neuronal mechanisms that underlie functional brain imaging signals, and to evaluate the degree to which these signals reflect the locally measured neuronal activity. The second is to elucidate the principles and processes used by the cerebral cortex to analyze visual information and to create coherent visual perception.

Our laboratory employs an integrative approach, using a combination of imaging and electrical recording techniques. These include functional Magnetic Resonance Imaging (fMRI), optical imaging using intrinsic signals and voltage sensitive dyes, multi-channel neurophysiological recordings, and neurophysiology simultaneously with fMRI. Together, these techniques encompass multiple levels of spatial and temporal resolution. Brain activity signals obtained by large scale non-invasive imaging methods are compared to the activity of ensembles of neurons imaged optically, and to electrically-recorded activity obtained from groups of neurons and single neurons.

Laboratory of Brain and Cognition

Principal Investigator: Dr. Nathan Spreng 

Publications: PubMed, Google Scholar

Nathan Spreng is studying how brain networks support various cognitive processes such as remembering information, and how we use this knowledge to influence our decisions. His lab examines large-scale brain network dynamics and their role in cognition. Currently, we investigate attention, memory, cognitive control, and social cognition, and the interacting brain networks that support them. We are also actively involved in the development and implementation of multivariate and network-based statistical approaches to assess brain structure, connectivity and activity. In doing so, we aim to better understand the properties of brain networks underlying cognitive processes as they change across the lifespan in health and disease.

High-resolution quantitative MR imaging

Principal Investigator: Dr Christine Tardif
Publications: PubMed, Google Scholar

For more information on the current members, collaborations, publications, projects, please visit the lab website.

Dr. Christine Tardif is an Assistant Professor in the Department of Neurology and Neurosurgery and the Department of Biomedical Engineering. She is also a member of the magnetic resonance imaging (MRI) core of the McConnell Brain Imaging Centre.

The lab develops novel MRI techniques to generate high-resolution quantitative MR images of the brain in-vivo, and relates them to microstructural features of the tissue. Methodological developments include novel image acquisition techniques, multi-modal biophysical modelling, and high-resolution cortical modelling. The lab has a translational approach, working on both small animal (7 Tesla) and human (3 and 7 Tesla) MRI systems.

Dr. Tardif’s research has focused on MRI-based investigations of myelin, a lipid-rich cellular membrane that forms an insulating sheath around axons to achieve and maintain the rapid conduction and synchronous timing of neural networks. Myelination is a lifelong dynamic process of forming and modulating myelin sheaths. It underlies key mechanisms of brain plasticity and higher order cognitive functions. In addition to demyelinating diseases such as multiple sclerosis, there is accumulating evidence that dysmyelination contributes to psychiatric disorders as well. Dr. Tardif’s lab investigates myelination (in both white and grey matter) using multiple MRI techniques such as relaxometry, magnetization transfer and diffusion-weighted imaging.

The Villeneuve Lab

Principal Investigator: Dr. Sylvia Villeneuve

Publications: PubMed, Google Scholar

For more information on the current members, collaborations, publications, projects, please visit the lab website.

The Villeneuve Lab is interested in how the brain ages, with a specific focus on factors that modify the association between brain lesions and cognitive performance. Our research is motivated by the fact that more than 25% of older adults are considered cognitively normal despite the presence of beta-amyloid in their brain, a hallmark of Alzheimer’s disease. This fact suggests that other factors interact with beta-amyloid to trigger cognitive deficits in Alzheimer’s disease. It also suggests that actions can be taken to prevent or postpone disease-related symptoms. The main focus of the Villeneuve Lab’s research is therefore to examine the factors that protect against, or worsen, the development of cognitive deficits in age-related neurodegenerative diseases.
