‘Multi-Scale and Multi-Modal Assessment of Coupling in the Healthy and Diseased Brain’
We also do not know how signals from different techniques link with each other. We will look at people where we already know there are differences in coupling, including people with epilepsy and psychosis. We will then look at coupling before and after perturbing the brain, through brain training, magnetic stimulation or drugs.
Our vision is to deliver a step change in understanding the human brain, by creating an imaging programme that uniquely combines the very best neuroimaging expertise, equipment and techniques to answer the fundamental question of how continuous interactions of electrical, chemical, vascular and metabolic processes result in the multi-scale network activity that underpins inter-individual differences in cognition, and key behavioural/functional brain changes in disease. This integrated characterisation of brain coupling over multiple domains will transform our understanding of the working brain and guide approaches aimed at remedial action when normal coupling is disturbed.
We will capitalise on the opportunities afforded by Cardiff’s significant investment in a new state-of-the-art research centre that co-houses cutting-edge non-invasive technologies, including 7T, 2x3T, 3T MRI with ultra-strong magnetic field gradients (microstructure scanner), MEG and TMS/TDCS.
A team of 11 methodological and 3 clinical Fellows, each focused on a specific aspect of coupling, but applied within a systematic framework of integration, will allow us to achieve our key goals, which are to:
- Optimise signal capture using the most advanced imaging technologies to yield
sensitive, robust and repeatable markers of structure/function;
- Understand these signals thereby maximising their biological interpretability and value to neurocognitive models of human behaviour;
- Develop an integrative modelling framework for combining data from multiple imaging modalities;
- Characterise changes in multi-scale coupling following perturbations, including
behavioural, electromagnetic and pharmacological interventions.
Our approach harnesses and integrates advanced technologies and techniques to generate an integrated characterisation of brain coupling over multiple domains, thereby transforming our understanding of the working brain and when to apply remedial action when normal coupling is disturbed.
Our programme will generate a strategically important framework, linking local, national and international assets. It will build research capacity to complement Cardiff University’s significant investment in an expanded CUBRIC, as well as linking the UK’s three 7T MRI centres and the UK’s leading microstructure imaging labs.
