The human brain presents outstanding challenges to science and medicine. Brain function and structure span broad spatial scales (from single neurons to brain-wide networks) as well as temporal scales (from milliseconds to years). Currently, none of the tools available for studying the brain can fully capture its structure and function across these diverse scales - "the neuroimaging puzzle". This poses crucial limitations to understanding how the brain works, and how it is affected by numerous diseases.
The central goal of this project is to expand currently available tools for non-invasive human brain imaging, to bridge critical gaps in the neuroimaging puzzle. New methodologies will be developed, focused on ultra-high field magnetic resonance imaging (UHF MRI) and its combination with electroencephalography (EEG). New contrast mechanisms and technological advances enabled by UHF MRI and EEG will be explored to allow unprecedented views into the microstructure of brain regions like the thalamus, and to capture the activity of large-scale neuronal networks in the brain with high sensitivity, temporal and spatial specificity. These advances will be directly applied to address open questions in the diagnosis and treatment of essential tremor, and psychosis.
In general, improved brain imaging techniques are critical for a deeper understanding of how the brain works, and to detect and characterize diseases more effectively, thereby improving clinical management and leading to a healthier population. The non-invasive characterization and treatment of neurodegenerative diseases like tremor is particularly relevant to aging modern societies.
