Modulation of inhibitory and excitatory neural circuits in the primary motor cortex following theta-burst rTMS to area 5
(University of Waterloo, 2010-12-17)Subcortical and cortical loci interact with the primary motor cortex (M1) and influence the neural circuitry mediating hand movement. Area 5 located within the superior parietal lobule has direct connectivity with M1, is ... -
Modulation of sensory processing during simultaneous bimodal stimulation: Effects of sensorimotor integration
(University of Waterloo, 2008-05-23)Illusions such as the McGurk (McGurk and MacDonald, 1976) and ventriloquist (Radeau and Bertelson, 1974) effects or visual capture sensorimotor deficits (Holmes et al., 2004) demonstrate that our perception of and interaction ... -
Modulation of somatosensory cortex underlying error compensation in a tactile speeded-response task
(University of Waterloo, 2014-12-01)There is a lack of empirical evidence that the dorsolateral prefrontal cortex (DLPFC) is exerting control over post-error selective attention adjustments. This is an error compensation mechanism that is hypothesized by the ... -
Morphological and Apoptotic Alterations in Skeletal Muscle of Mice Deficient in Apoptosis Repressor with Caspase Recruitment Domain
(University of Waterloo, 2012-01-05)Altered apoptotic signaling in skeletal muscle has been observed in a number of disease states associated with skeletal muscle atrophy. Therefore, understanding the mechanisms that lead to increased skeletal muscle apoptosis ... -
Movement-induced motor cortical excitability changes of upper limb representations during voluntary contraction of the contralateral limb: A TMS investigation of interhemispheric interactions
(University of Waterloo, 2008-09-03)Humans possess the ability to generate an incredible degree of complex, highly skilled, and coordinated movements. Although much is known about the anatomical and physiological components of upper limb movement, the exact ... -
MoveSTroNg at Home: A feasibility study of a model for remote delivery of functional strength and balance training combined with nutrition education for older pre-frail adults.
(University of Waterloo, 2021-09-10)Background: The Coronavirus disease (COVID-19), caused by SARS-CoV-2 exacerbated the potential for physical inactivity1, nutritional risk2, and loneliness3 among older adults, especially in those with pre-existing health ... -
Multifaceted Approaches to Enhancing Shoulder Health in Breast Cancer Patients undergoing Radiation Therapy: quantification of treatment effects and rib fracture prediction assessment
(University of Waterloo, 2024-04-11)Radiotherapy is a highly effective treatment for breast cancer, but it is also associated with several complications that can impact patients’ quality of life and overall survival. This dissertation addressed the lack of ... -
Multisensory Integrative Processes and Aging
(University of Waterloo, 2022-10-04)Our sensory systems provide us with distinct impressions of our surroundings which are critical for perception, cognitive processing, and control of action. Indeed, input from multiple sensory stimuli compared to a single ... -
Muscle Quantity and Quality after Chronic Spinal Cord Injury: An investigation of calfmuscle cross-sectional area and density after long-term paralysis
(University of Waterloo, 2014-05-22)Background/Objectives: Individuals with a spinal cord injury (SCI) experience reductions in lower-extremity muscle mass and increased fatty-infiltration of skeletal muscle, predisposing them to an increased risk of specific ... -
My Meal Intake Tool (MMIT) and the Mealtime Audit Tool (MAT) - Criterion Validity and Inter-rater Reliability Testing of two Novel Tools for Improving Food Intake in Acute Care
(University of Waterloo, 2016-05-19)BACKGROUND: Forty-five percent of patients in Canada are admitted to hospital already malnourished. Compared to well-nourished patients, those with diminished nutritional status are at an increased risk of in-hospital ... -
n-3 PUFA status in school children is associated with beneficial lipid profile, reduced physical activity and increased blood pressure in boys
(Cambridge University Press, 2013-10-14)Dietary n-3 long-chain PUFA (LC-PUFA) improve dyslipidaemia and hypertension and may affect insulin resistance and adiposity. Increasing numbers of children show signs of the metabolic syndrome (MetS), but few studies have ... -
NADPH Oxidase-dependent ROS Production and Impaired Ca2+ Regulation are Associated with Exercise-induced Cardiac Fatigue in the Rat
(University of Waterloo, 2015-12-10)Cardiac fatigue is a phenomenon that is characterized by a transient reduction in left ventricular contractile and/or relaxation function following acute aerobic exercise. Few studies have utilized rodent models to examine ... -
Negotiating Varying Ground Terrain during Locomotion: Insights into the Role of Vision and the Effects of Aging
(University of Waterloo, 2006-12-18)We continually encounter different ground terrain such as slippery, compliant, uneven, rocky, and irregular terrain when walking, yet we know very little about how individuals safely negotiate this type of complex environment. ... -
Neural control of the healthy pectoralis major from low-to-moderate isometric contractions
(American Physiological Society, 2021-07-01)The pectoralis major critically enables arm movement in several directions. However, its neural control remains unknown. High-density electromyography (HD-sEMG) was acquired from the pectoralis major in two sets of experiments ... -
Neural correlates of trait anxiety in sensory processing and distractor filtering
(University of Waterloo, 2022-10-25)Anxiety, generally defined as an anticipatory heightened state of arousal, has been shown to affect neural markers of cognition and executive components used in sensorimotor function; however, this has infrequently been ... -
The Neural Processes of Perceived Simultaneity and Temporal Order in Younger and Older Adults using EEG.
(University of Waterloo, 2017-08-02)In order to make sense of the world, the central nervous system (CNS) must determine the temporal order of events and integrate cues that belong together. The process of integrating information from multiple sensory ... -
