Neuroscience & Behaviour

My research examines social-cognitive factors that influence and are influenced by participation in physical activity. Current interests include self-perceptions such as self-efficacy, perceived control, self-regulation, and self-determination. I also investigate people’s perceptions about influential others who interact with them (proxy agents) in their pursuit of behavioural objectives. Understanding relationships between these perceptions and behaviour involves laboratory and field-based research. Challenges faced by people navigating life transitions such as moving away from home to attend college or university, rehabilitating from illness, and becoming a parent are of particular interest.

My students and I are interested in how the human brain controls and learns skilled actions in healthy and clinical populations. We also conduct metascience research to gain insights into research practices within kinesiology and related areas.

Dr. Jennifer J. Heisz is an Associate Professor in Kinesiology and Associate Director (Seniors) of the Physical Activity Centre of Excellence at McMaster University. Dr. Heisz received her Ph.D. in Cognitive Neuroscience (McMaster) and completed a postdoctoral fellowship at the Rotman Research Institute at Baycrest. Dr. Heisz directs the NeuroFit Lab (http://neurofitlab.ca/) which is funded by the Alzheimer Society, Banting Foundation, Natural Science and Engineering Council of Canada, and the Canadian Foundation for Innovation. Dr. Heisz’s research examines the effects of physical activity on brain function to promote mental health and cognition in young adults, older adults and individuals with Alzheimer’s disease. Recent honours include receiving an Early Researcher Award from the Province of Ontario and the Petro-Canada Young Innovator Award. Follow Dr. Heisz on twitter @jenniferheisz.

The purpose of my research is to develop fundamental understanding of the cortical control of the human hand and upper limb. My research program is focused on the somatosensory contributions to motor control; human hand control is profoundly dependent on the integrity of somatosensory input that arises from touch and muscle receptors. Multiple cortical areas receive and process somatosensory input yet little is known about the role of these areas in the control of human hand movement. My research program is primarily focused on investigating the role of somatosensory loci in the control of hand movement in healthy and clinical populations. Students in my lab use a combination of neurophysiology techniques including transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging.

Dr. Walsh’s research is focused on investigating the mechanisms by which daily behaviours (physical activity, diet, screen time, sleep and cognitive stimulation) impact brain function. The overarching goal of this research is to apply this knowledge to develop interventions that optimize brain health across the lifespan. Dr. Walsh’s research is particularly interested in characterizing how exercise increases the neuroactive hormone brain-derived neurotrophic factor (BDNF), and investigating the effect of BDNF on brain function. The primary measurement outcomes of this research are: 1) measuring neuroactive hormones in the blood, 2) assessing cognitive function, 3) measuring cerebral blood flow.Dr. Walsh is currently accepting graduate students for Fall 2021.

I am passionate about conducting collaborative and transformative interdisciplinary studies to promote equity, diversity, and inclusion in physical activity participation. Employing community engaged methodologies, I seek opportunities for everyone to pursue active lifestyles that enhance their health and well-being in various contexts of human movement. Four areas of research focus are:

1. Identification of systemic and personal barriers to physical activity by collecting and representing “unheard” or “silenced” lived stories of marginalized and oppressed groups and individuals;
2. Identification of effective and ethically framed professional practices that promote access and social inclusion, cultural sustainability, and respectful reconciliation in working with equity deserving groups and individuals;
3. Identification of actionable solutions based on both the scientific evidence and the perspective of persons who experience inequities and social injustices in physical activity participation; and
4. Promotion of direct social change through community building and engagement in research, practice, and knowledge mobilization.
