A thought-provoking piece in Nature Neuroscience by many neuroscience colleagues: "Science must break its silence to rebuild public trust". Lots to think about here.

Public engagement: building common ground
How can we help to bridge this divide? Simply producing more excep­ tional science will not be enough to rebuild public trust. Rather, we must adopt a new model that recognizes communication and advocacy as core pillars of science, on a par with rigor and reproducibility. Public engagement efforts should be valued for faculty promotions, much like obtaining grants and publishing our findings in scientific journals. Researchers should be recognized and rewarded for activities such as giving public talks, working with local schools, engaging with policy­ makers, developing social media campaigns and platforms or writing accessible articles for general audiences. Developing these skills must be an integral part of scientific training, reinforcing the notion that the responsibility to champion science lies with us. Courses that teach graduate students and postdocs to communicate complex ideas clearly, to use social media effectively and to advocate for evidence­based policies must be deemed critical and supported by our universities. These efforts should not be viewed as distractions from research but woven into the fabric of what we do as scientists. Rebuilding public trust requires a cultural paradigm shift: scientists must see themselves not just as producers of knowledge, but also as its ambassadors and translators. Such a fundamental change will occur only if it is embraced by our scientific leaders and institutions, emphasizing the critical role of public engagement for science to succeed.

Results of the replication are in!

Chocolate is more desirable than poop:

Cohen's d_rm = 6.20, 95%CI [5.63, 6.78]

N = 486, two single item 1-7 Likert scales of desirability.

Make an effect size prediction!

@jamiecummins.bsky.social and I are replicating Balcetis & Dunning's (2010) "chocolate is more desirable than poop" (Cohen's d = 4.52)

Let us known in the replies what effect size you think we'll find. Details of the study in the thread below.

The effects of psychedelics on neurovascular coupling is something I've heard discussed loads and researched little.

The dissociation between neuronal activity and hemodynamic responses to psychedelics is a reminder to consider neurovascular effects in pharmaco-fMRI!

Sleep is often only investigated from a single dimension. @bttyeo.bsky.social &co identify 5 sleep-biopsychosocial profiles that link self-reported #sleep patterns to variability in #health, #cognition & #lifestyle factors in 770 healthy young adults @plosbiology.org 🧪 plos.io/42tRXSc
Canonical correlation analysis reveals five sleep-biopsychosocial profiles (LCs). Scatter plots showing correlations between biopsychosocial and sleep canonical scores. Each dot represents a different participant. The inset shows the null distribution of canonical correlations obtained by permutation testing; note that the null distribution is not centered at zero. The dashed line indicates the actual canonical correlation computed for each LC. The distribution of sleep (top) and biopsychosocial (right) canonical scores is shown on rain cloud plots.

Super excited about this ongoing spatial transcriptomics study in locus coeruleus of human 🧠. Expression of norepinephrine neurons - TH🔴, DBH🟢 and SLC6A2🟡 overlaid on post-Xenium H&E stain, allowing correlation of neuromelanin content (brown pigment) w/ gene expression #FluorescenceFriday 🔬🧪
mRNA expression using in situ sequencing (Xenium) on a tissue section at level of human locus coeruleus shows expression of marker genes for norepinephrine-producing neurons (TH in red, DBH in green, and SLC6A2 in yellow. Expression of markers is overlaid on the H&E histology staining, which shows cell bodies (purple) and neuromelanin (brown)

Had a great time visiting Yale today and catching up with the @toddc.bsky.social group. Exciting to have some of these results out in the world for the first time!

Is resting-state functional connectivity (rsFC), cortical thickness (CT), or cortical volume more effective at capturing sex and gender differences in the brains of preadolescents?

Check out our new article (doi.org/10.1016/j.dc...) now out in Developmental Cognitive Neuroscience.

New preprint alert!

We used connectome-based predictive modeling in a transdiagnostic sample to identify brain network correlates of wide array of behavioral measures. We also identify where networks supporting cognition overlap with those linked to diagnostically related clinical symptomatology.

Connectome-based predictive modeling (CPM) applied to functional MRI connectivity data can identify brain networks that vary with behavioral measures across subjects. The prediction strength also prov...

We’re looking for a postdoc to join our Max Planck group in Germany some time in 2026. If you have computational and/or neuroimaging expertise, and are interested in questions intersecting perception and cognition, please reach out! I’ll also be happy to chat at the #Bernsteinconference this week.

Ever wondered if your interesting brain-behavior correlation was over- or under-estimated due to head motion, but were afraid to ask? We’ve created a motion impact score for detecting spurious brain-behavior associations, now available in Nature Communications!

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
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.
