Arousal as a universal embedding for spatiotemporal brain dynamics - Nature Reframing of arousal as a latent dynamical system can reconstruct multidimensional measurements of large-scale spatiotemporal brain dynamics on the timescale of seconds in mice.

Super proud of this collaboration with rockstar Ryan Raut - born out of playing in the sandbox in our last year of grad school! Multi-scale brain activity can be predicted from a simple measure of arousal like pupil diameter. Out with linear causality, in with dynamic systems to explain neurobiology

Impulsivity and neuroticism share distinct functional connectivity signatures with alcohol-use risk in youth - Molecular Psychiatry Molecular Psychiatry - Impulsivity and neuroticism share distinct functional connectivity signatures with alcohol-use risk in youth

New paper from @annierhcheng.bsky.social

using data from IMAGEN and ABCD she identifies distinct signatures of impulsivity and negative affect in youth that uniquely overlap with a neuromarker of risky alcohol use

Amazing first day at #Flux2025 featuring an all-star team discussing the last 10 years (and future 10 years!) of ABCD & an inspiring conversation about bridging the lab and real life 🧠🤩

If you're headed to #Flux2025 in Dublin, swing by Poster S63 on Saturday to chat with rockstar @heatherarobinson.bsky.social about this work! 🧠 🇮🇪 👩‍🔬

(and of course, catch me all conference long kvelling to any/everyone about how totally amazing my students are 🥰)

Wow, so great! Love to see this narrative reframed so clearly and beautifully! 🧠🎉

Seems sensible to me!

I usually do 2 rounds of segment removal for that reason - one before (big problems) and one after ICA (little problems)

Good question! I think the main reason is that tools like ICA can only find a limited number of components (only as many speakers as you have microphones), so removing obviously terrible channels/segments (eg. participant sneezes) helps make better use of ICA for smaller amplitude artefacts 🤷‍♀️

✨ New paper ✨ in JAMA Pediatrics! We discuss how understanding the timing ⏰ of stressful events relative to neurodevelopment can help us better identify risk factors (looking backward) and predict future psychopathology (looking forward) at the individual level

This 🔃Review 🔃 discusses how 'exposomics' may advance our understanding of developmental 🧠 health & cognitive outcomes by investigating unique sets of physical/chemical exposures, psychosocial experiences, & sociocultural contexts / @ariellekeller.bsky.social

Don’t miss the Flux 2025 Diversity Inclusion & Belonging symposium “Supporting Science in Challenging Times”: Fri 3:15 Hyde Suite 1&2! We’ll provide historical context + future guidance on navigating authoritarian trends undermining science, safeguarding scientific credibility + supporting trainees.

Thank you Elvisha!! 🥰

Thanks Matt! 😊🐿️

We are so grateful to our wonderful team of co-authors: our amazing collaborator Ran Barzilay & three outstanding ACORN Lab undergraduate students Niyati Dave, Anna Wagner, & Natalie Kells! I am SO proud of our small-but-mighty team & all the thoughtful conversations that went into this work. 🐿️ /10

The future is bright for this growing field! ☀️ Our review offers recommendations for future studies & points to some awesome open-source datasets that are well suited to exposomics, including those with biospecimen data, comprehensive measures of lived experience, and geocoding by home address. /9

The exposome approach has already proven to be beneficial for capturing these complex, co-occurring, and interacting features so that we can better understand each person’s environment comprehensively. It also lays crucial groundwork for studying the effects of developmental timing of exposures. /8

The broader context of our external environments also matters! Socioeconomic status & access to resources have huge effects on cognitive neurodevelopment. These environmental factors don’t happen in a vacuum. From exposures to experiences to external environments, they all co-occur and interact. /7

We find that physical/chemical exposures, like lead poisoning and air pollution, are linked to poorer cognition and altered brain development. Psychosocial experiences, like family/caregiver relationships, adversity, and racial discrimination also impact cognitive outcomes and brain development. /6

A depiction of an individual's "exposome" with concentric rings of example exposome features. The inner ring represents physical/chemical exposures, the middle ring represents psychosocial experiences, and the outermost ring represents external environmental contexts.

Our review summarizes key takeaways from this growing field, with a particular focus on how the exposome shapes cognitive neurodevelopment. We discuss findings from three broad domains of the exposome: physical/chemical exposures, psychosocial experiences, and external environmental contexts. /5

We think of the “exposome” as sister to the “genome”: similarly to how genomics aims to make sense of our complex genetic material (nature), the field of exposomics aims to make sense of our complex environments (nurture). We can then test how the exposome affects brain development and cognition! /4

But none of these environmental features occur in isolation! How can we make sense of all the complex, intersecting features of an individual’s environment at once? That’s where the growing field of “exposomics” comes in, with methods to measure and make sense of each person’s complex “exposome”. /3

Our environments matter a lot for brain development! Research shows many environmental features shape how we think and feel: chemical toxins in our surroundings, interactions with friends/family, socioeconomic resources like a steady income or healthcare access, and our broader cultural contexts. /2
