Sensorimotor learning and control in autism spectrum disorders: The role of sensorimotor integration.
… of the current thesis was to examine the role of sensorimotor integration during sensorimotor learning and control processes in autism spectrum disorders. Autistic participants were matched (IQ, age, gender) with control participants across three experimental chapters (chapters three-five) within …

Sensorimotor experience in virtual environments
… A model was developed to study the effects of sensorimotor experience in virtual environments, and findings of the effect of sensorimotor experience in virtual environments upon brain activity and related behavioral measures. The research model represents a significant contribution to …

Spinal interneurons in sensorimotor integration
… organization of neuronal networks involved in sensorimotor integration. Propriospinal interneurons located within the lumbar segments have extensive intra-segmental projections to motor nuclei. First order interneurons interposed in reflex pathways and descending pathways receive a …

Sensorimotor learning under switching dynamics
… computational modelling to investigate how the sensorimotor system uses contextual information to create, update and recall motor memories. We first examine the role of muscle co-contraction in the learning of novel movement dynamics. We show that muscle co-contraction, as measured by surface …

A sensorimotor basis of speech communication
This dissertation presents the development of sensorimotor primitives as a means of constructing a language-agnostic model of speech communication. Insights from major theories in speech science and linguistics are used to develop a conceptual framework for sensorimotor primitives in the context of …

Representation and Interaction of Sensorimotor Learning Processes
Human sensorimotor control is remarkably adept at utilising contextual information to learn and recall systematic sensorimotor transformations. Here, we investigate the motor representations that underlie such learning, and examine how motor memories acquired based on different contextual …

Sensorimotor Processes Underpinning Imitaiton Learning of Biological Motion
The aim of the present thesis was to examine the way in which biological motion is coded and imitated during imitation learning by improving upon methodologies currently used in the literature to examine imitation of underlying movement kinematics. Across four experiments, imitation of the …

Exploring lateralized sensorimotor processing using somatosensory evoked potentials
… pathways that reflect cerebellar activation and sensorimotor integration. Additionally, the research also showed that when motor task acquisition occurs in the presence of sensory perturbations, the non-dominant limb is more accurate than a control group and there are differential changes in …

Reward and prediction errors in Bayesian sensorimotor control
… (phasic dopamine). Recent studies on Bayesian sensorimotor control have implicated midbrain dopamine concentration in the integration of prior knowledge and current sensory information. The present behavioral study addressed the contributions of tonic and phasic dopamine in a Bayesian …

ASSOCIATION BETWEEN HEART FAILURE AND HAND SENSORIMOTOR FUNCTION
… independence in PwHF by comparing hand sensorimotor function and attentional capacity in PwHF and age- and sex-matched control subjects. Additionally, the study examines whether the severity of HF is associated with hand sensorimotor function and attentional capacity. A total of 10 age- …

Family Studies of Sensorimotor Disturbances in Autism Spectrum Disorder
Sensorimotor impairments are prevalent in individuals with autism spectrum disorder (ASD) and among the earliest emerging features, yet the pathophysiological mechanisms underlying these deficits remain poorly understood. Family studies are one approach to better understand these pathophysiological …

The use of audio stimulation to affect sensorimotor learning
Sensorimotor learning for the hand and fingers can be conducted using both hardware and software components, but the training regime is also important. Using repetitive sequence tapping allows measurement of defined metrics in a controlled, safe environment, and therefore statistical indications …

Brain development from sensorimotor experiences: Handwriting and letter perception
Handwriting is a visual-motor activity that is particularly effective at increasing letter recognition, a fundamental skill in early reading development. This dissertation focuses on understanding the neural mechanisms that underlie increases in letter recognition after handwriting practice. The …
