Quantification of whole brain structural connectivity and fibre densities. The project is intended to develop and improve accuracy in tools used to measure brain connections. Its overall aim is to produce definitive evidence of the biological accuracy of quantitative measures of brain structural connectivity as derived from diffusion magnetic resonance imaging (MRI).

Its overall aim is to produce definitive evidence of the biological accuracy of quantitative measures of brain structural connectivity as derived from diffusion magnetic resonance imaging (MRI). Discovery in the quantitative field of MRI research is important to worldwide efforts to identify the human ‘connectome’. The project plans to bring together novel diffusion MRI post-processing methods and state-of-the-art 3-D glass-brain histology techniques using mice. Investment in MRI research that specifically addresses methods to accurately measure structural brain connectivity may ultimately contribute to improving non-invasive imaging methods.Read moreRead less
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.

Summary
Charting the brain's wiring over the human lifespan. This project aims to produce a large-scale model of brain wiring over the human lifespan by utilising normative modelling approaches on state-of-the-art diffusion magnetic resonance imaging (diffusion MRI) data. This project expects to generate new understanding of how the brain's connections change with age in healthy individuals. Expected outcomes of this project include a reference chart for healthy brain wiring, and major advances in diffu ....Charting the brain's wiring over the human lifespan. This project aims to produce a large-scale model of brain wiring over the human lifespan by utilising normative modelling approaches on state-of-the-art diffusion magnetic resonance imaging (diffusion MRI) data. This project expects to generate new understanding of how the brain's connections change with age in healthy individuals. Expected outcomes of this project include a reference chart for healthy brain wiring, and major advances in diffusion MRI data harmonisation approaches. This should provide significant benefits for the translation of advanced diffusion MRI methods, as normative charts for brain wiring will be made broadly available. This could have broad implications for interpreting individual diffusion MRI scans in future.Read moreRead less
Chromatic Inputs to Cortical Receptive Fields in Primates. The human eye contains three kinds of receptors for daytime vision, named blue, green and red cones for their sensitivity to different regions of the visible spectrum. It is known that blue cones contribute to brain pathways for colour vision, but recent data suggest there is also 'cross-talk' of blue cone signals to pathways for motion and high-acuity vision. This project comprises precise measurement of blue cone signals, and anatomica ....Chromatic Inputs to Cortical Receptive Fields in Primates. The human eye contains three kinds of receptors for daytime vision, named blue, green and red cones for their sensitivity to different regions of the visible spectrum. It is known that blue cones contribute to brain pathways for colour vision, but recent data suggest there is also 'cross-talk' of blue cone signals to pathways for motion and high-acuity vision. This project comprises precise measurement of blue cone signals, and anatomical tracing of blue cone pathways, in a primate model for human vision. The data will improve our basic knowledge of how the brain processes sensory signals.Read moreRead less

Summary
The importance of glia in the development of healthy blood vessels in the eye. The formation of healthy blood vessels in the eye is critical for vision. An important peptide in blood vessel formation throughout the body, including the eye, is Angiotensin II. Specific retinal cells named astrocytes and microglia are suggested to be involved in vessel formation. However, the way these cells control this formation is unknown. Using innovative techniques, this project will investigate how retinal as ....The importance of glia in the development of healthy blood vessels in the eye. The formation of healthy blood vessels in the eye is critical for vision. An important peptide in blood vessel formation throughout the body, including the eye, is Angiotensin II. Specific retinal cells named astrocytes and microglia are suggested to be involved in vessel formation. However, the way these cells control this formation is unknown. Using innovative techniques, this project will investigate how retinal astrocytes and microglia control glial-vascular communication and blood vessel formation via Angiotensin II. The information gained from this proposal is critical to our understanding of both normal retinal development and blood vessel maintenance in both infants and those of older ages.Read moreRead less
Resolving the Structures of Human Muscarinic M1 and M4 Receptors. Muscarinic receptors are vital for most basic human brain functions. These receptors are changed in schizophrenia and Alzheimer's disease. This project will determine the structure and localisation of two of these receptors in order to i) understand their roles in brain disorders and ii) develop drugs to treat disorders involving them.
