Cortical activations underlying human bipedal balance control
(University of Waterloo, 2016-10-25)Human bipedal balance is a complex sensorimotor task controlled by the central nervous system. Balance impairments, caused by aging or neuromuscular diseases, often lead to falls which are one of the leading causes of ... -
The Determinants of Reaction Times: Influence of Stimulus Intensity
(University of Waterloo, 2015-12-07)The central nervous system has the ability to generate very rapid ‘temporally urgent’ sensory motor reactions in response to stimuli under certain conditions. For example, temporally urgent reactions have been shown to ... -
The effect of concussion history on relevancy-based gating of visual and tactile stimuli
(University of Waterloo, 2018-01-23)At the cortical level, incoming sensory inputs are subject to interruption as they are transmitted to modality-specific cortical areas, in order to prevent excessive processing of task-irrelevant sensory information and ... -
Effects of rewards and reward-predictive cues on gamma oscillations in the ventral striatum
(University of Waterloo, 2014-01-10)Decisions, such as choosing between different rewards, are known to be influenced by a number of variables such as value, uncertainty and delay associated with a rewarding outcome. Various structures in the brain are ... -
Electrophysiological indices of information processing in psychopathy
(University of Waterloo, 2009-01-21)Psychopathy is a severe personality disorder associated with a range of affective, interpersonal, and behavioural abnormalities. Evidence suggests that psychopaths show marked deficits in processing emotional information, ... -
Exploring factors that contribute to between-subject variability of reaction time
(University of Waterloo, 2018-01-22)For well over a century reaction time has provided researchers with a method to quantify information processing speed. Defined as the interval of time between the presentation of a stimulus to the onset of a response, ... -
In Search of Lost Time
(University of Waterloo, 2012-05-16)In Marcel Proust's most famous novel, In Search of Lost Time, a Madeleine cake elicited in him a nostalgic memory of Combray. Here we present a computational hypothesis of how such an episodic memory is represented in a ... -
The Influence of Dual-tasking on Cortical Responses Associated with Instability
(University of Waterloo, 2017-10-12)Recent literature has revealed evidence of cortical involvement in reactive balance control. Using electroencephalography, event-related potentials (ERP) have been shown to be consistently evoked in response to a perturbation ... -
Investigating cerebellar contributions to sensory processing
(University of Waterloo, 2020-04-21)Over the last two decades, the long-standing view of the cerebellum as a motor structure has been challenged with evidence highlighting the presence of cerebellar activation during non-motor tasks and functional connectivity ... -
Postural state modulation of cortical balance reactions
(University of Waterloo, 2019-09-25)Safe and effective walking is a crucial part of daily human life, but the number of injuries and resulting financial burden from falls during walking is increasing. As a result, it continues to be important to advance ... -
The science of navigation: An analysis of behavioural differences between good and poor wayfinders
(University of Waterloo, 2013-04-15)Everyday experience suggests that certain people can find their way to a destination easily, while others have considerable difficulty. This dissertation focused on gaining a greater understanding of navigational strategies ...
