Attention and Age-Related Components of Visual-Tactile Modulation of Somatosensory Cortex and Motor Implications
(University of Waterloo, 2010-06-16)Successful interaction with the external world requires continual sensory detection, sensorimotor translations and goal-directed motor execution. Attention to task-relevant stimulation can facilitate sensory detection and ... -
The contribution of the fronto-cerebellar system in cognitive processing
(University of Waterloo, 2013-01-23)Over two decades of patient and neuroimaging data have provided increasing support for a role of the posterior cerebellum in cognition, particularly attention. Contralateral connections between the prefrontal cortex and ... -
Effects of Aging in Reaching and Grasping Movements: A Kinematic Analysis of Movement Context
(University of Waterloo, 2011-04-26)Although several studies have investigated the effects of aging on aspects of motor planning and control, there remains a lack of consensus about the underlying mechanisms responsible for the motor slowing associated with ... -
Frontal and parietal contributions to the modulation of somatosensory cortex by relevance and modality
(University of Waterloo, 2011-01-21)Afferent somatosensory inputs ascend from the periphery to the cortex carrying information about touch that is critical for planning motor responses. At the cortical level, this information is subject to modulation from ... -
Hand preference after stroke: The development and initial evaluation of a new performance-based measure
(University of Waterloo, 2011-04-21)Functional recovery of the upper limb after stroke is influenced by many factors, one being amount of affected arm and hand use following stroke. In the healthy population, amount of hand use is influenced by degree of ... -
Influence of area 5 on primary motor cortex: a paired-pulse TMS investigation in healthy adults
(University of Waterloo, 2010-10-27)The neural correlates that underpin fine motor control of the hand and their connections with the primary motor cortex (M1) require further investigation. Brodmann’s area 5 located in the superior parietal lobule (SPL) is ... -
Investigating the attentional effects of acute aerobic exercise and crossmodal processing on the modulation of frontoparietal interactions
(University of Waterloo, 2015-01-06)The sense of touch commences when afferent sensory signals from the periphery ascend via the spinal cord to the cortex. At the cortical level, incoming peripheral signals are susceptible to neuronal modulation at the ... -
Localization of cortical potentials evoked by balance disturbances
(University of Waterloo, 2011-09-26)The ability to correct balance disturbances is essential for maintaining upright stability. Recent literature highlights a potentially important role for the cerebral cortex in controlling compensatory balance reactions. ... -
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 ... -
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. ... -
Postural motor learning and the effects of age on practice-related improvements in compensatory posture control
(University of Waterloo, 2009-08-27)The purpose of this thesis was to examine the capacity for acquisition and retention of practice-related improvements in compensatory posture control and the nature of postural motor learning among healthy young and older ... -
Theta-burst rTMS over SI modulates tactile perception on the hand
(University of Waterloo, 2011-05-18)Fine motor control of the hand relies on intact somatosensory integration and feedback. Impaired hand movements are observed in patient groups where touch perception and processing within the primary somatosensory cortex ... -
Visual Inputs and Motor Outputs as Indivduals Walk Through Dynamically Changing Environments
(University of Waterloo, 2006-12-01)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ...
