Investigating brain activity changes during attention-demanding tasks
Multi-modal imaging of the metabolic and neurochemical mechanisms underlying task-evoked negative BOLD signals
This study is looking at how a specific part of the brain works when people focus on tasks, and it’s for anyone interested in understanding more about brain activity, especially those with neurological or mental health conditions who might participate in brain scans to help with this research.

What this research studies
This research explores how the brain's default-mode network (DMN) behaves when individuals engage in tasks that require attention. By using advanced imaging techniques, including functional MRI and PET scans, the study aims to measure various brain functions and chemical processes simultaneously. This approach will help researchers understand the underlying mechanisms of reduced brain activity during cognitive tasks, which is important for diagnosing and treating neurological and psychiatric conditions. Patients may be involved in imaging sessions to contribute to this understanding.
Who could benefit from this research
Good fit: Ideal candidates for participation include individuals with neurological or psychiatric conditions that affect attention and cognitive function.
Not a fit: Patients without any neurological or psychiatric conditions may not receive direct benefits from this research.
Why it matters
Potential benefit: If successful, this research could lead to improved diagnostic tools and treatment strategies for psychiatric and neurological disorders.
How similar studies have performed: Previous research has shown promising results using similar multi-modal imaging techniques to study brain function, indicating potential for success in this approach.
