A cyclist was seriously injured at Eglinton & Oakwood last night. Now that the Eglinton Crosstown LRT is open, the #BikeTO community deserves to know WHEN will the long promised bike lanes on that street be installed? #shame #TOpoli #VisionZero CC www.cp24.com/local/toront...

Super cool paper led by the amazing @tbiba.bsky.social suggesting that we form memories at the theta rhythm! And even cooler that these rhythms can actually be detected with careful behavioral manipulations!

I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠

Super cool paper led by the amazing Thomas Biba showing that episodic memory is theta rhythmic! And even cooler that these rhythms can actually be detected with behavioral memory data (my favorite type of data!).

Episodic memory encoding fluctuates at a theta rhythm of 3–10 Hz

Nature Human Behaviour - Biba et al. show that episodic memory encoding fluctuates at a theta rhythm of 3–10 Hz.

Awake infant fMRI offers a rare window into early brain and cognitive development. In a new paper out now in Infancy, we leverage data from hundreds of infant scans from the Saxe and Turk-Browne Labs to reveal what factors drive scanning success — and how future studies can maximize data retention!

Functional Magnetic Resonance Imaging in Awake Infants: Insights From More Than 750 Scanning Sessions

Functional magnetic resonance imaging (fMRI) in awake infants has the potential to reveal how the early developing brain gives rise to cognition and behavior. However, awake infant fMRI poses signifi....

"The decision in Cycle Toronto v Ontario was a strong rebuke to government overreach when those actions put people’s lives at risk and are unsupported by facts and data. We look forward to defending that victory in court on Jan. 28.”

The CCF will support the Ontario government’s appeal of a ruling that blocked the removal of downtown Toronto bike lanes #ONpoli #BikeTO cyclingmagazine.ca/sections/new...

Very happy to share our paper on the "summer slide" in kid's cognitive test scores is out now in @pnas.org! We find a replicable dip in performance across multiple domains of cognition in >23,000 kids across 4 datasets! Check out the 🧵 from @ariellekeller.bsky.social below! 👇

Our paper on the ☀️ "summer slide" 🛝 is out now @pnas.org! www.pnas.org/doi/10.1073/... Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️ #PsychSciSky #DevPsy 🧵👇

Honored that our soon-to-launch lab is included in this Liftoff piece! Grateful to everyone who has helped me get here and excited to keep learning with trainees and collaborators. Thanks to @thetransmitter.bsky.social @franciscorr25.bsky.social for highlighting this early stage of building a lab!

Check out the last edition of “Liftoff” for 2025 featuring @shoenhard-lab.bsky.social and @lexidecker.bsky.social’s new labs! Looking forward to more new neuroscience lab highlights next year! #neuroskyence

A recent meta-analysis published in @nature.com finds that there is no general effect of economic inequality on well-being or mental health (though there are some effects for specific groups, e.g. low-income samples). Read more details in the full paper here: 🧪 www.nature.com/articles/s41...

No meta-analytical effect of economic inequality on well-being or mental health - Nature

A meta-analysis of 168 studies reveals that economic inequality is not significantly associated with subjective well-being or mental health.

We should probably be placing incarcerated people in prisons closest to their homes. Why? Assigning individuals to prisons closer to their home reduces recidivism. Really? Yep. Being placed close to one's home increases social contacts that appear to reduce reoffending.

Our graduate student @catalinayang.bsky.social shows that prediction errors only destabilize weakly reactivated memories. Strong memories? They are more impervious to surprise. Check out our #preprint with @barense.bsky.social to learn more osf.io/preprints/ps... #UofT #Psychology

Super excited to share my first preprint with Katherine Duncan and Morgan Barense (@barense.bsky.social) -- "Memory strength at reactivation, not memory age, governs prediction error driven updating of naturalistic event memory"! 🧠🎉https://osf.io/preprints/psyarxiv/q9rkn_v1
