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

Subcortical control of human reaching? This project will test a radical new hypothesis about how the human brain generates visually guided behaviour. Conventional thinking assumes that visuomotor control of limb movements occurs exclusively within the cerebral cortex. However, the project team’s recent observations of extremely rapid visually guided muscle activity strongly imply that the human brain controls reaching movements via more primitive midbrain and brainstem structures. The project’s ....Subcortical control of human reaching? This project will test a radical new hypothesis about how the human brain generates visually guided behaviour. Conventional thinking assumes that visuomotor control of limb movements occurs exclusively within the cerebral cortex. However, the project team’s recent observations of extremely rapid visually guided muscle activity strongly imply that the human brain controls reaching movements via more primitive midbrain and brainstem structures. The project’s hypotheses challenge long-standing ideas about the functional organisation of the human brain and may have wide-ranging implications for the design of human-machine interfaces as well as training protocols in rehabilitation, industry, and sport.Read moreRead less
The secret of tiny hand movements to feel and manipulate objects. This study aims to reveal some of the fundamental sensory mechanisms underlying the uniquely human ability to manipulate objects and use tools. Signals from touch receptors are crucial for controlling grip forces so that delicate objects are held without slipping, or being crushed by excessive force. Yet we know little about how such sensory information is obtained and how it is used for the motor control. By analysing hand moveme ....The secret of tiny hand movements to feel and manipulate objects. This study aims to reveal some of the fundamental sensory mechanisms underlying the uniquely human ability to manipulate objects and use tools. Signals from touch receptors are crucial for controlling grip forces so that delicate objects are held without slipping, or being crushed by excessive force. Yet we know little about how such sensory information is obtained and how it is used for the motor control. By analysing hand movements during object manipulation and recording sensory signals from single human nerve fibres we will investigate how certain types of movement shape richness of available sensory information. This knowledge will facilitate the development of next generation sensory-controlled prosthetics and robotic manipulators.Read moreRead less
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 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

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.

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
