Summary
Damage to movement control areas in the brain early in life (e.g. cerebral palsy) or in adulthood (e.g. stroke, tumours) results in motor weakness and loss of skill; over a period of many months there is gradual recovery of function. The neural mechanisms that are associated with functional reorganization of the brain and motor recovery are not well understood.

The neural mechanisms that are associated with functional reorganization of the brain and motor recovery are not well understood. This project plans to use animal experiments to identify the location of regions in the brain that undergo neural reorganization and compensate for lost function. Following brain lesions detailed mapping of the motor areas of the brain and a careful study of movement disabilities will be performed. The study will attempt to identify changes in motor maps that indicate neural reorganization and relate these changes to motor recovery. The results of this study will be used in future projects to test training programs, drugs and neural prosthesis on neural reorganization and recovery of function. Eventually the information may be used to direct pharmacological and physiotherapeutic interventions, and motor rehabilitation programs for optimal recovery of function.Read moreRead less
Volitional And Non-volitional Control Of Human Balance: Normal Physiology And Changes With Ageing

Summary
How does the brain control balance when we stand? Our research shows that two very distinct processes operate to produce distinct postural, perceptual and cardiovascular outcomes. These experiments investigate the neurophysiology that coordinates these systems and what happens with age. The results will fundamentally change views on balance control. Balance problems are common in neurological disorders and old age. Knowing how balance works will improve diagnosis, treatment and rehabilitation.
Influence Of Cortical Stroke And Experimental Brain Stimulation On Excitability Of Human Corticobulbar Motor Projections And Swallowing Function

Summary
Swallowing disorders often result from damage to the brain. They have profound consequences on patient health and quality of life and result in significant medical and socioeconomic costs. This project firstly investigates how motor networks in the brain control the muscles involved in swallowing and how this control is affected by stroke. Secondly, it evaluates the potential of novel interventions to improve impaired swallowing function following stroke by reorganising motor networks.
I am a neuroscientist, who studies the neural mechanisms responsible for the control of human voluntary movements. My research is aimed at characterising the physiological mechanisms which are responsible for plasticity of the human motor cortical regions
The Efficacy Of Novel, Non-robotic Devices To Train Reaching Post Stroke

Summary
Up to 50% of stroke survivors are left with upper limb disability that limits their daily activities and their paralysis is so severe that it excludes them from training with the most effective methods. This study is a clinical trial of innovative new techniques to assist people with severe upper limb paralysis to reach following stroke. Positive results are likely to reduce disability in a large number of stroke survivors and has the potential to be used by other patients with paralysis.
