I’m very excited to share my FIRST first-author preprint - the result of my Northwestern graduate school lab rotation with Lisa Johnson! We detected HFB in babies (1-4 months) noninvasively using scalp EEG, distinguishing wake from sleep states. 👶 Link: doi.org/10.1101/2025...

High frequency broadband activity detected noninvasively in infants distinguishes wake from sleep states

High frequency broadband activity (HFB; 70-150 Hz) indexes local brain activity. It is predominantly studied using invasive measures due to signal drop off from skull attenuation. We hypothesized that...

Charlie Kirk spent his life‘s work and all of his energy and time targeting out-groups while arguing for a world in which gun massacres would be easy to enact, plentiful, and inevitable, and he became famous and wealthy doing it, and we’re now not supposed to mention that because it’s not polite.

How does neural activity change with development? We assessed how “neural noise” changes with age, attention, and brain structure in 101 pediatric and adult neurosurgical patients. Proud to have been a contributor to this project! Check it out: www.nature.com/articles/s41...

The development of aperiodic neural activity in the human brain - Nature Human Behaviour

This study establishes how aperiodic activity, a ubiquitous signal linked to neural noise, develops in localized brain regions and illuminates the development of prefrontal control during adolescence ...
