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 …

Cursed complexity. Computational properties of subcortical neuronal microcircuitry in sensorimotor control
… of the nervous system, and its role in motor control. Especially the cerebellum has been shown to play an important role in the coordination of fast movements, such as reaching and pointing. Paper I uses theoretical reasoning based on previously found experimental studies to show that the …

Modifying the MIT Sensorimotor Control Lab model of human balance and gait control for the addition of running
… upright balance. The model of human neurological control of balance and gait generation put forward by Jo and Massaquoi in "A model ofcerebrocerebello-spoinomuscular interaction in the sagittal control of human walking" and executed in MATLAB Simulink/SimMechanics. This model has been used to …

Moving fast : neural constraints in closed loop
The generation of fast movements during sensorimotor control is fundamentally limited by the biophysics of neural activity and the physiological dynamics of the muscles involved. Yet, the limiting factors and the corresponding tradeoffs have not been rigorously quantified. We use feedback control …

Hodnocení úrovně posturální stability u sportovců v rekondiční fázi po zranění kolene
… The aim of this thesis is to evaluate stability, sensorimotor control and symmetry in two directions using the MFT S3 Check and dynamic stability measurements on the Y - Balance Test in selected athletes after knee surgery who are in the recovery phase and to determine whether the methods used are …

Imitation of atypical biological motion in autism spectrum disorders
… adults with autism and matched neurotypical control adults imitated models that displayed distinctly different, but biological believable kinematics. In Chapter Two it was observed that adults with autism exhibited low-fidelity imitation of atypical biological motion. In Chapter Three it was …

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 …

The effects of testosterone on embodiment: implications for social power
… in a series of randomized, double-blind, placebocontrolled studies, this thesis assessed for the first time the effects of a 0.5mg dosage of testosterone on three important dimensions of embodiment in samples of women: 1) The perception of internal physiological signals (interoception), 2) Body …

Effects of auditory feedback and real-time visual feedback on second language tone learning
… lexical pitch variation along with new sensorimotor skills to produce the rapid tone changes. Language learning, therefore, opens windows for observing changes in behavior and brain functions that impact the learner in multiple ways. I addressed the neural plasticity indirectly by …

Descending premotor target tracking systems in flying insects
The control of behaviour in all animals requires efficient transformation of sensory signals into the task-specific activation of muscles. Predation offers an advantageous model behaviour to study the computational organisation underlying sensorimotor control. Predators are optimised through …

Learning from master's muscles : EMG-based bio-feedback tool for augmenting manual fabrication and crafting
… discussed in relation to the current theories on sensorimotor control and learning. The initial results were evaluated with respect to the amount of time taken to become comfortable with the skill at hand. While there are a number of possible applications of the device, two main areas are …

Quantifying Joint Coordination Variability in Anterior Cruciate Ligament-Reconstructed Individuals During Walking
… in individuals with ACLR compared to healthy controls, most of the analyses did not evaluate coordinative function, and thus neglected to consider how the lower limb acts as a linked chain. Therefore, the present study used a method based on dynamical systems theory to quantify coordination …

Examining the Links Among Motor Symptoms in Hyperfunctional Voice Disorders, Auditory Discrimination, and Auditory-Motor Function
… reliability of assays of speech auditory-motor control between the domains of voice and articulation, and supported the use of a categorical measure of fundamental frequency (fo) adaptation employed in chapter 3. In chapter 2, we developed a protocol to assess volitional control of small changes …

An Examination of Contributing Factors to Star Excursion Balance Test in Individuals with and without Chronic Ankle Instability
… the ankle and knee, static and dynamic postural control, ankle dorsiflexion range of motion (DFROM), and ankle laxity between individuals with and without chronic ankle instability (CAI) as well as to determine which factors contribute the most to Star Excursion Balance Test (SEBT) performance in …

Predictive and reactive control mechanisms involved in object manipulation
As humans, we rely on our ability to skillfully manipulate objects to complete tasks in our daily lives. This ability depends critically on our predictions of the mechanical properties of objects (i.e. weight), as well as rapid corrective responses, initiated when we encounter perturbations that …

The Effect of a Combined Multiple-Modality Exercise Intervention on Sensorimotor Function in Community Dwelling Older Adults, with A Subjective Cognitive Complaint: The M4 Study (Multi-Modal; Mind Motor)
… seen between M2 and M4 groups for any of the sensorimotor outcomes examined. This study elucidates the impact of an exercise intervention on sensorimotor functioning through improvements in AS RT, however no differences were seen between groups. A multiple-modality exercise intervention can be …
