What this research studies
You would do decision-making and emotion tasks while researchers record direct, very fast changes in serotonin and dopamine in the brain using new sensors that capture chemical signals with millisecond precision. Recordings are taken in awake participants to link these sub-second chemical fluctuations to moments when you notice errors or feel strong emotions. The team will compare these chemical patterns to symptoms like low pleasure or mood changes to better understand depression. This work combines clinical knowledge with cutting-edge neurochemical recording methods to connect brain chemistry and behavior.
Who could benefit from this research
Good fit: Adults diagnosed with major depressive disorder who can participate in brain recording sessions and perform brief decision-making and emotional tasks.
Not a fit: People without depression or those unwilling or unable to undergo brain recording procedures are unlikely to benefit directly from participation.
Why it matters
Potential benefit: If successful, this could reveal precise brain-chemical patterns behind depression and guide more targeted or personalized treatments.
How similar studies have performed: Previous neuroimaging and medication studies have implicated serotonin and dopamine in depression, but direct sub-second chemical recordings in awake humans are novel.
