Beyond Neuroinflammation: The Role of Microglia in Synaptic Plasticity. Microglia are the immune cells of the brain and are known to respond to infectious and non-infectious insults to the nervous system. This project aims to use the transparent and genetically amenable brain of the zebrafish, to explore new functions of microglia at the single cell level in the intact, behaving animal, through visualization of cellular components of the brain (neurons, glia, microglia, blood vessels, synapses), ....Beyond Neuroinflammation: The Role of Microglia in Synaptic Plasticity.

This project aims to use the transparent and genetically amenable brain of the zebrafish, to explore new functions of microglia at the single cell level in the intact, behaving animal, through visualization of cellular components of the brain (neurons, glia, microglia, blood vessels, synapses), and through the genetic manipulation of synaptic density, and real time observation of microglia in the process.Read moreRead less

Summary
Diamond cybernetics: nanocrystalline diamond for interfacing bionic devices with the human nervous system. Bionic devices will soon be used to treat disorders such as epilepsy, Parkinson's and depression. We will use diamond to create high resolution, permanent electrical connections between devices and the human nervous system. These diamond connections will preserve nerve health and make bionic devices more effective and able to last a lifetime.
Development of an electrode for stimulation of a transplanted neosphincter. This project aims to develop a novel electrode as an integral component of a new treatment for severe stress urinary incontinence. Treatments for severe stress urinary incontinence are associated with complications and are not completely effective.

This project aims to develop a novel electrode as an integral component of a new treatment for severe stress urinary incontinence. Treatments for severe stress urinary incontinence are associated with complications and are not completely effective. The new electrode is designed to be activated by an implanted stimulator to control an innervated smooth muscle graft (the neosphincter) to regulate the flow of urine from the bladder. Project research into the design of the electrode will focus on providing safe, effective and efficient stimulation of the neosphincter, while ensuring minimal damage to the surrounding tissues and affording straightforward implantation at surgery.Read moreRead less

Summary
Fast three-dimensional imaging of neural signal propagation using light-field microscopy. This project aims to use a light-field microscope to reveal the dynamics of sustained neural activity in the brain. The brain’s neurons are highly interconnected, so neural signals can be sustained in a repeating cycle. While this may underlie tasks such as working memory, its role in information processing is unclear. Understanding information processing is vital for finding treatments for neurodegenerativ ....Fast three-dimensional imaging of neural signal propagation using light-field microscopy. This project aims to use a light-field microscope to reveal the dynamics of sustained neural activity in the brain. The brain’s neurons are highly interconnected, so neural signals can be sustained in a repeating cycle. While this may underlie tasks such as working memory, its role in information processing is unclear. Understanding information processing is vital for finding treatments for neurodegenerative disorders. To characterise this large-scale aspect of neural computation, this project measures neural activity at high speed across large numbers of neurons. This is expected to provide evidence of the nature of sustained activity which may in the future lead to treatments for neurodegenerative disorders.Read moreRead less
Decoding neuronal populations for visually-guided decision and action. This project aims to investigate how the cerebral decodes visual information in order to guide sensory-guided actions. Using a high resolution technique, capable of monitoring the activity of many cells in real time, it will study how sensory signals about the motion of visual patterns interact with noise (fluctuations in neuronal activity that are not directly related to the sensation being encoded) in order to determine dec ....Decoding neuronal populations for visually-guided decision and action. This project aims to investigate how the cerebral decodes visual information in order to guide sensory-guided actions. Using a high resolution technique, capable of monitoring the activity of many cells in real time, it will study how sensory signals about the motion of visual patterns interact with noise (fluctuations in neuronal activity that are not directly related to the sensation being encoded) in order to determine decisions made by an animal. Expected outcomes include new knowledge about the cellular circuits responsible for vision, and new technologies for decoding brain activity from physiological measurements, which may in the future guide the development of improved bionic devices such as brain-computer interfaces.

Multimodal retinal imaging provides "insight" into cerebrovascular ageing. This project aims to develop a multi-modal imaging technology platform to simultaneously measure amyloid beta and its neurovascular sequelae to identify novel early biomarkers of ageing in the eye and brain. The growing ageing population is an increasing socioeconomic burden. The central nervous system is particularly susceptible to ageing, which is difficult to measure at its onset. Critically, as the eye is an easily accessible extension of the cortex, retinal imaging may be a non-invasive surrogate to assess ageing changes in the brain. Anticipated outcomes are a sensitive detector of neural ageing, improved preventative measures, reducing the socioeconomic burden of ageing, and improved quality of life.Read moreRead less
