Novel mechanisms for regulating the retinal vasculature. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather they rely on support cells to communicate the needs of neurons. This project aims to examine the mechanisms by which resident immune cells, called microglia, regulate retinal capillaries in response to neural activity. New knowledge examining a novel ....Novel mechanisms for regulating the retinal vasculature. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather they rely on support cells to communicate the needs of neurons. This project aims to examine the mechanisms by which resident immune cells, called microglia, regulate retinal capillaries in response to neural activity. New knowledge examining a novel mechanism will be generated. This information is crucial for enhancing our understanding of how blood vessels are controlled in the retina and brain and will guide the development of novel ways of examining blood vessel function.Read moreRead less
Neuronal origin of functional maps on the mammalian visual cortex. This project aims to study how the brain processes images. Basic features of objects in the visual scene seem to be coded on the visual cortex in an orderly way. By recording neurones’ electrical activity in a mammalian brain, this project aims to study how such organisation is determined at the neuronal level, namely how the individual nerves and synapses that form the brain and process the signals are organised to form the over ....Neuronal origin of functional maps on the mammalian visual cortex. This project aims to study how the brain processes images. Basic features of objects in the visual scene seem to be coded on the visual cortex in an orderly way. By recording neurones’ electrical activity in a mammalian brain, this project aims to study how such organisation is determined at the neuronal level, namely how the individual nerves and synapses that form the brain and process the signals are organised to form the overall functional architecture visible at a macroscopic level. This understanding could realise the basis of normal visual perception in robotic vision and brain-machine interfaces.Read moreRead less
From gene to duty: the emergence of the complex brain. This project aims to determine the molecular code (genes and their products) responsible for the expansion of the nonhuman primate visual cortex, which underpins the formation of discrete functional and anatomical areas. The project will detail all the genes expressed at key stages of brain development and how interfering with their expression inhibits the normal formation of areas. The expected outcomes are a chronological and functional ma ....From gene to duty: the emergence of the complex brain. This project aims to determine the molecular code (genes and their products) responsible for the expansion of the nonhuman primate visual cortex, which underpins the formation of discrete functional and anatomical areas. The project will detail all the genes expressed at key stages of brain development and how interfering with their expression inhibits the normal formation of areas. The expected outcomes are a chronological and functional map of the molecular code that underpins the formation of the complex primate visual cortex. This will contribute to defining the mechanisms leading to the evolution of the complex primate visual brain and complement the numerous brain connectome studies being undertaken globally.Read moreRead less
