Summary
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
Determining the neural mechanisms of visual stimuli and motor responses. This project aims to determine how we select actions to visual cues rapidly, unconsciously and automatically. Learning associations between visual stimuli and motor responses is part of normal development and continues throughout life. Rapid deployment of these actions is often critical for safety yet we have limited knowledge of how the human brain does this. This project will use neuroimaging tools to characterise the spa ....Determining the neural mechanisms of visual stimuli and motor responses. This project aims to determine how we select actions to visual cues rapidly, unconsciously and automatically. Learning associations between visual stimuli and motor responses is part of normal development and continues throughout life. Rapid deployment of these actions is often critical for safety yet we have limited knowledge of how the human brain does this. This project will use neuroimaging tools to characterise the spatial and temporal neural architecture underlying these processes and determine how the dorsal and ventral streams of visual processing, specialised for motor control and recognition respectively, interact in vision-based actions as these actions become learned.Outcomes will provide new frameworks for driving improvement in any domain in which goal-directed actions depend on the rapid processing of visual information, including human-machine interfaces for defence, economic development, education, health, science and technology.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. 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 the project will suggest improved avenues for treatment of sleep related respiratory disorders.Read moreRead less
Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal ....Understanding the physiological changes accompanying arousal from sleep. This project aims to investigate neural memory in upper airway dilator muscles. Following brief awakening from sleep (arousal), upper airway dilator muscle activity is elevated for 20–30 seconds despite inhibitory stimuli being present. The cause for the elevated activity is unknown. This project aims to investigate whether a form of neural memory contributes to the elevated activity. It expects to demonstrate that arousal can induce a neural memory that is not inhibited by usual stimuli. The findings are expected to increase our understanding of normal human functioning but may also have implications for conditions where upper airway muscles are important such as dysphagia, sleep apnea and numerous other sleep disorders.Read moreRead less
