How do past actions and rewards bias goal directed movement? This project aims to identify how different aspects of our past experience affect the accuracy of movements, and study the underlying brain mechanisms. This project will use timing methods and brain recordings to test how the history of movements we have executed in the past, and the rewards associated with those movements, interact to affect subsequent movement execution. The project should advance basic understanding of how the human ....How do past actions and rewards bias goal directed movement? This project aims to identify how different aspects of our past experience affect the accuracy of movements, and study the underlying brain mechanisms. This project will use timing methods and brain recordings to test how the history of movements we have executed in the past, and the rewards associated with those movements, interact to affect subsequent movement execution. The project should advance basic understanding of how the human brain controls movement, and provide theoretical foundations needed to improve the design of human-machine interfaces, and training approaches in industry, rehabilitation and sport.Read moreRead less
How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world.

This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spring-like function of the foot. It will explain a conceptually novel design allowing shoes to support our feet, whilst harnessing the energetic benefits of the foot's spring-like function. This research has the potential to revolutionise athletic footwear design and has direct implications for enhanced performance in running athletes.Read moreRead less

Multitasking effects on motor control in childhood through adolescence. This project aims to increase knowledge on the development of motor control and its cognitive determinants. The ability to perform cognitive and motor tasks simultaneously is a critical skill for daily living. From childhood to adolescence, and across a range of developmental disorders, simultaneous performance of cognitive and motor tasks represents a major challenge. Children with cognitive and motor coordination problems ....Multitasking effects on motor control in childhood through adolescence. This project aims to increase knowledge on the development of motor control and its cognitive determinants. The ability to perform cognitive and motor tasks simultaneously is a critical skill for daily living. From childhood to adolescence, and across a range of developmental disorders, simultaneous performance of cognitive and motor tasks represents a major challenge. Children with cognitive and motor coordination problems show increased inattention, hyperactivity, psychosocial difficulties and negative perceptions of self-worth. This project aims to investigate how the cognitive demands of balance control during walking changes from childhood to adolescence. The results may help to identify the mechanisms underlying childhood disorders associated with comorbid cognitive and motor impairments and provide strategies for earlier identification.Read moreRead less
Structural and neural determinants of stress and strain in human muscle. This project aims to further our understanding of the biomechanical stress and strains experienced by contracting human muscles. Using innovative imaging techniques such as microendoscopy and supersonic shear imaging, we expect to generate new significant evidence on the structural and neural factors that lead to areas of high stress in human muscles. Outcomes of this project include not only a new understanding of muscle d ....Structural and neural determinants of stress and strain in human muscle. This project aims to further our understanding of the biomechanical stress and strains experienced by contracting human muscles. Using innovative imaging techniques such as microendoscopy and supersonic shear imaging, we expect to generate new significant evidence on the structural and neural factors that lead to areas of high stress in human muscles. Outcomes of this project include not only a new understanding of muscle design on multi-scale level, but also of muscle function and adaptation. This should provide significant benefits in better predicting muscle injury and prescribing safe exercise, knowledge that would benefit biomechanical engineers and sport and exercise professionals.Read moreRead less

This project aims to advance our understanding of the poorly understood neural circuits that enable fine motor control in humans. To obtain this knowledge, new platform technology will be developed to capture the full kinematics of the hand during concurrent functional magnetic resonance imaging at ultra high-field. This device will allow testing of fundamental theories describing the canonical microcircuits involved in hand motion. Expected outcomes include new evidence of mirror neurons and observation of predictive error signals in the motor cortex. This new knowledge paves the way towards improved computer-brain interface technology which is likely to create benefits through translation to applications such as artificial limb control.Read moreRead less
Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus. The upper airway muscles, the most complex in the human body, are critical for breathing and speaking, but are not well understood. Genioglossus draws the base of the tongue forward to maintain airway patency. This project will study genioglossus during wakefulness and sleep in normal healthy individuals. It is anticipated that th ....Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus.

This project aims to evaluate the developmental trajectory of tongue control during speech, relating dynamic 3D vocal tract modelling to the acoustic signal. By optimising real-time MRI technology to capture and model articulatory movements, the project expects to accelerate understanding of how tongue control for speech is developed, mastered, and perturbed by factors such as rapid growth and foreign accent. Expected outcome is a new understanding of how different speakers' vocal tracts change and how speech is reshaped, informed by real physiological data. Significant benefits will be realised through refined methods and theory development for diverse fields e.g. linguistics, speech science, and automatic speech recognition/synthesis. Read moreRead less
