TOOLS FOR ANALYSING BRAIN IMAGING DATA IN HEALTH AND DISEASE
Grant number: 1047648 | Funding period: 2014 - 2018
This research will develop cutting-edge computational tools and statistical methods to analyse, model and visualise the way in which the human brain is interconnected. The tools developed will be used to identify biological markers in the brain’s network of axonal circuitry (the connectome) that are valuable for diagnosis and prognosis of psychiatric disorders. This research will bring to fruition the exciting potential of connectomics in neuroscience and psychiatry.
