Slow brain activity and how it shapes attention, arousal, and behavior
Macroscale physiology and functional correlates of slow network fluctuations
This project looks at how slow changes in brain activity relate to attention, alertness, and behavior in healthy adults using brain scans and body sensors.

What this research studies
If I join, researchers will record brain and body signals from healthy adults using simultaneous fMRI, EEG, eye tracking (pupillometry), heart rate, breathing, skin conductance, and muscle sensors while people perform tasks. They will compare these signals over extended periods to see how slow drifts in arousal and attention influence behavior and the ability to switch between external and internal focus. The team will also try to change arousal and cognitive control experimentally to test whether these factors drive shifts in brain networks and behavior. Data are collected in extended, in-person sessions at the Nathan S. Kline Institute to capture natural fluctuations and task-related switches.
Who could benefit from this research
Good fit: Adults aged 21 or older who are healthy and can safely undergo MRI, EEG, and other noninvasive recordings are the ideal participants.
Not a fit: People under 21, anyone with MRI-incompatible implants, or those with severe neurological conditions that prevent safe participation may not be eligible or benefit directly.
Why it matters
Potential benefit: If successful, this work could clarify why attention and alertness drift over time and point to ways to detect or treat disorders linked to abnormal slow brain activity.
How similar studies have performed: Previous studies using fMRI, EEG, and physiological measures have linked slow brain fluctuations to attention and arousal, but combining deep multimodal recording with causal manipulation in the same participants is relatively new.
