Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innov ....Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innovative genome editing, mathematical modelling and proteomic approaches, to study how biochemical modifications of a key protein called tau help encode and retrieve memories. These molecular insights will make a significant advance in the current understanding of a brain function that is essential to all human activities.Read moreRead less

Summary
Mapping the neural circuits that underlie emotional learning. This project aims to understand the precise neural circuits that mediate the formation of emotional memories. Recent findings have identified a novel complexity in these circuits and the goal of this proposal is to resolve the underlying mechanism that drives emotional memories. In detail, this project will combine state of the art dual- optical stimulation techniques combined with behaviour-dependent tagging of neurons to investigate ....Mapping the neural circuits that underlie emotional learning. This project aims to understand the precise neural circuits that mediate the formation of emotional memories. Recent findings have identified a novel complexity in these circuits and the goal of this proposal is to resolve the underlying mechanism that drives emotional memories. In detail, this project will combine state of the art dual- optical stimulation techniques combined with behaviour-dependent tagging of neurons to investigate the precise brain circuits linked to emotional learning, an approach that also allows knowledge transfer to other research fields. Expected outcomes and benefits of the project is a significant shift in our understanding of the neural mechanisms that underlie emotional learning.Read moreRead less
Molecular control of memory traces. This project aims to understand how particular molecules help encode memories in the brain for future retrieval. Individual memories are encoded in brain cells through an unknown physical process. This project uses innovative approaches to manipulate memory-containing cells and will provide a new detailed explanation of memory.

This project aims to understand how particular molecules help encode memories in the brain for future retrieval. Individual memories are encoded in brain cells through an unknown physical process. This project uses innovative approaches to manipulate memory-containing cells and will provide a new detailed explanation of memory. Outcomes of this work will significantly advance the current understanding of how memories are physically generated and maintained, which is an essential component of human and animal life. This research provides significant benefits in understanding the biology behind memory and in maintaining memory capacity in ageing.

Systemic regulation of neuronal circuits in cognition and behaviour. This project aims to understand systemic regulation of behaviour and cognition in the central nervous system (CNS). The adrenal gland (AG) is an endocrine organ that regulates behaviour and cognition, but the molecular mechanisms underlying the regulatory axis between the CNS and AG are poorly understood. The AG selectively and highly expresses p38, a member of the MAP kinase family, while mice that lack p38 suffer memory and b ....Systemic regulation of neuronal circuits in cognition and behaviour. This project aims to understand systemic regulation of behaviour and cognition in the central nervous system (CNS). The adrenal gland (AG) is an endocrine organ that regulates behaviour and cognition, but the molecular mechanisms underlying the regulatory axis between the CNS and AG are poorly understood. The AG selectively and highly expresses p38, a member of the MAP kinase family, while mice that lack p38 suffer memory and behavioural deficits. This project will study p38’s role in systemic CNS function. It aims to understand brain function and systemic regulation of cognition and behaviour, thereby contributing to a deeper understanding of brain function and paving the way for new preventive treatments and medical care strategies.Read moreRead less
Mechanisms of itch - from endosomal signalling to neural circuits. This project aims to investigate the cellular and circuit mechanisms of itch transmission in the spinal cord by defining the activation and propagation of itch-specific signals. This project expects to generate new knowledge in the area of neuronal signalling and circuitry using novel electrophysiological approaches that target and manipulate specific nerves and cellular components. The project will characterise signalling within ....Mechanisms of itch - from endosomal signalling to neural circuits. This project aims to investigate the cellular and circuit mechanisms of itch transmission in the spinal cord by defining the activation and propagation of itch-specific signals. This project expects to generate new knowledge in the area of neuronal signalling and circuitry using novel electrophysiological approaches that target and manipulate specific nerves and cellular components. The project will characterise signalling within specific spinal subcircuits in order to understand the mechanisms of receptor activation and signalling, and investigate how circuit activity is regulated. This project expects to advance fundamental understanding of itch signalling in the nervous system and provide avenues for future therapeutics.Read moreRead less
