Christophe Grova PhD
Christophe Grova is Associate Professor affiliated to the Department of Physics of Concordia University and a research member of PERFORM center since July 2014, while remaining adjunct Professor affiliated to Biomedical Engineering Dpt and Neurology and Neurosurgery Dpt at McGill Faculty of Medicine. He is also affiliated to the epilepsy group of the Montreal Neurological Institute (MNI), the McConnell Brain Imaging Center of the MNI and a member of Physnum team at Centre de Recherches Mathématiques.
He received his Engineering and Master degrees in biomedical engineering at the University of Technology
of Compiègne (France) in 1998, followed by a Ph.D. in SPECT/MRI registration at University of Rennes (France). From 2003 to 2008, his postdoctoral studies at the MNI were focussed on EEG source imaging of epileptic discharges and the correspondence with EEG/fMRI results, while acting as part time research associate for the set-up of the MEG centre of Université de Montreal (2006-2008). Dr Grova has been assistant Professor at McGill from July 2008 to July 2014.
Since 2008, he is the director of the “Multimodal Functional Imaging Laboratory” (MultiFunkIm) which is now located on both McGill and Concordia campus. His areas of expertise are EEG/MEG source localization, multimodal data fusion involving EEG/MEG, fMRI and fNIRS, for application in epilepsy and sleep research. Since September 2014, C. Grova is chairing the Integration of PERFORM Platforms committee, aiming at facilitating communication/interaction between PERFORM platforms. His team is also handling the development and validation of two software packages: MEM in Brainstorm for EEG/MEG source localization and NIRSTORM for fNIRS data analysis).

In this talk, we will present our recent developments in the context of Personalized functional Near Infra-Red Spectroscopy (fNIRS) investigations, which consist in optimizing placement of fNIRS sources and detectors on the head of the participant in order to maximize fNIRS sensitivity to some targeted brain regions, while allowing accurate local 3D reconstructions of fluctuations of oxy-hemoglobin and deoxy-hemoglobin along the cortical surface. Personalized fNIRS investigations could be ...

Background: To create games that target older adults' interests in engaging in cognitively-boosting activities is a rising trend [1,2]. But, the novelty of the digital me-dium of play, and the implicit expectation of cognitive performance can create stressful experiences for them [3]. We have previously proposed an empirical framework, Affective Game Planning for Health Applications (AGPHA) based on Lazarus's Transactional Theory of Stress Appraisal and Coping [4], to study interactions betwe...
Background: Recovery kinetics following cardiopulmonary exercise testing (CPET) have yet not been described in people with OSA and comorbid insomnia (COMISA). Our objectives were to i) describe heart rate recovery (HRR), oxygen recovery slopes (VO2/t) and time to half recovery of VO2max (T½) following CPET in COMISA; and ii) investigate their response to either one of the following: 16 weeks of exercise training (Ex) or 8 week-relaxation control intervention followed by 8 weeks of exercise an...
Although social distancing directives are important public health measures to reduce the spread of SARS-cov-2, they can contribute to negative emotional outcomes such as loneliness due to the isolation. Furthermore, individuals have been reporting poorer sleep quality since the beginning of the COVID-19 pandemic. The aim of this study is to...
Postural stability is a complex skill dependent upon the coordination of motor, sensory and cognitive systems (Woollacott & Shumway-Cook, 2002). The purpose of this project was therefore to explore how older adults' balance performance is impacted by increased cognitive load, hearing loss, and simulated vision loss. Twenty-seven older adults between the ages of 56 and 90 years (M = 74.74, SD = 9.51) were tested. Participants underwent standard sensory acuity, and cognitive functioning tes...
Evidence consistently demonstrates that aging is associated with declines to cerebrovascular health. Sex distinctions have been identified as well, where studies have shown that cerebral blood flow (CBF) declines linearly across the lifespan in both sexes, yet females have greater CBF compared to males [1]. Cerebrovascular reactivity (CVR) has also been identified as a marker of cerebrovascular health and is shown to decline with age [1,2], but the potential sex differences are currently uncl...
The effects of physical inactivity among older adults have been established as a "public health crisis" because of their heightened risk of cardiovascular, autoimmune, neurocognitive, and mental health problems (Wu, 2020). While physical distancing is essential in the fight against COVID-19, long-term self-isolation protocols established to protect the elderly population have created new health risks, as older adults are now left more socially isolated and inactive than before. Making an inve...
Context: While soccer is considered a lateral dominant sport, few studies have examined if limb dominancy leads to asymmetries in body composition and their possible associations with injury (1). Objective: The purpose of this study was to 1) investigate body composition morphological asymmetries in male and female university-level soccer players, and 2) examine whether the degree of body composition asymmetry is associated with lower leg injuries (LLI) and lower back pain (LBP...
Background: Different exercise intensity has a various effect on the immune system. Lactate is one of the factors that releases in exercise, on one hand, higher lactate concentration not also apoptosis of peripheral blood mononuclear cells (PBMCs) decrease but also the survival of the PBMCs increase (Elsaser et al., 2017), on the other hand...

Sleep is important for memory consolidation and cognitives performances during the day. There is increasing evidence that brain oscillations during sleep play a central role in such processes. This presentation will review recent work from our lab on the interplay between brain rhythms during sleep, memory consolidation and age-related cognitive decline. We will also discuss recent data showing the impact of sleep disturbances on cognitive functions, as well as the effects o...

Circadian clock genes are widely expressed in mammalian brain. Despite considerable knowledge about the role of these genes in the generation of circadian rhythms in the suprachiasmatic nucleus, the master circadian clock, insight into brain-region specific function of these genes limited. Studies in our laboratory investigate the role of core clock gene, Bmal1 and Per2 in the control of behaviors governed by the striatum, a forebrain structure critical in in motor control, reward processi...
Sleep and circadian disturbances are common and represent risk factors for the development of some of the most prevalent and challenging chronic illnesses, such as cardio-metabolic and neurodegenerative disorders.Circadian rhythms are ubiquitous in all organisms. These rhythms, maintained through a complex molecular transcription-translation feedback loop are present throughout the brain and body, and play a key role in the regulation of nearly all physiological and behavioral processes. S...

Regional brain function is determined by its local structure and connectivity. I will present work from our lab that strives to quantify connectivity for applications in healthy development and understanding the impact of disease - focusing on understanding normative cerebellar connectivity and quantifying the impact of stroke. I will also touch on some recent work linking interhemispheric functional connectivity to bimanual motor control in older adults.

Safe mobility is vital to the functional independence of older adults. Executive functions such as working memory updating and dividing attention play an increasingly important role in supporting mobility in old age. This talk describes recent studies that examine the influence of cognitive and sensory challenges to complex motor performance. Featured are recent cognitive training and exercise intervention studies designed to target executive functions to improve mobility and cognition in old...
