New fMRI study shows the hippocampus signals mismatches only when our expectations are based on episodic memories — not general knowledge. Challenges theories of the hippocampus as a domain-general comparator: doi.org/10.1101/2025.0…

@mrccbu Now out in PNAS - doi.org/10.1073/pnas.2…

New study from Cam-CAN using 11 different white matter (WM) measures shows WM health is multidimensional—4 latent MRI-derived factors explain 89% of WM variance, linking brain microstructure to vascular health & cognition: doi.org/10.1038/s41598…

@mrccbu are happy to announce Cognitive Neuroimaging Skills Training In Cambridge (#COGNESTIC) on 15-26 Sep 2025. We will provide training in state-of-the-art methods for open neuroimaging analysis and related methods. For more information, please visit: mrc-cbu.cam.ac.uk/events/cognest…

Integrating brainstem and cortical functional architectures | nature.com/articles/s4159… led by @JustineYHansen in @NatureNeuro 400 cortical regions + 58 brainstem nuclei. Lesgo 🤘🕶️⤵️

PLEASE CONTACT ME if interested. Happy to answer Qs and chat about details and what exciting ideas / experimental and/or computational projects you have in mind.

Thrilled to announce that I will be joining CiNet (Center for Information and Neural Networks; cinet.jp/english/) in Osaka Japan to start my lab in April/May 2025! We have postdoc positions (1 open NOW) & PhD apps (Osaka U) possible. Details below & pls retweet! Short 🧵 1/

At @SfNtweets I’ll also be presenting my main PhD project with @The_Strange_Lab ! If you want to discuss some really interesting iEEG results on how the medial temporal lobe processes spatial frequencies, drop by my poster U35 on October 9th 3-4pm 🧠

Looking forward to #sfn2024! I will present a neural network model of how contextual familiarity impacts episodic memory & decision-making at the nanosymposium organized by @akrambakkour and @katieinsel Come to NANO07 on 10/5 (Saturday) 1-3:45 PM!

🚨Happy to share this paper 👉Impact of cumulative exposure to anticholinergic/sedative drugs on cognition: a memory clinic cohort study ✨MEMORA cohort, N=1970 ✨Long-term exposure to anticholinergic/sedative drugs➡️ steeper cognitive decline 💊🧠📉 shorturl.at/7ncQC

Do you have experience in computational biology / Bioinformatics with a focus on data analysis and epigenetics? The Meissner Lab is looking for a Senior Research Assistant / Postdoc! More information --> molgen.mpg.de/4728864/ #sciencejobs #berlinscience

It was a great opportunity to be able to present at #OHBM24, filled with great neuroimaging. Enjoyed the naturalistic fMRI symposium, featuring @esfinn, @thelablab, Hongmi Lee, & Asirh Zadbood.

We find early cogn abilties fully explain low edu - dementia risk assoc. Low cogn double the risk, even accounting for edu. Replicated within families. Registry data, 77% population coverage. @LCBC_UiO @VSkirbekk @olerogeberg @KWalhovd BerntBratsberg medrxiv.org/content/10.110…

excited to release our large dataset on memory for narratives!🧠💭 The Naturalistic Free Recall Dataset: four stories, hundreds of participants, and high-fidelity transcriptions paper: doi.org/10.31234/osf.i… w/ @PhoebeHChen (co-first) @todd_gureckis @davidpoeppel @vvobot

Now accept in @Brain1878! An amazing wrap to my time in academia and @mrccbu, hitting many career highlights: -what I think is my best work to date -a fun foray into data science for challenging q's -last lead paper from postdoc -20th first author pub -30th overall pub 🧵to come

Happy to share that my first paper from my PhD is out! Using an oddball task, we found we tend to move forwards in recall after recalling emotionally salient stimuli 💥 w/ @FrankDarya @RHellerstedt @The_Strange_Lab 👇 #comments" target="_blank" rel="nofollow noopener">royalsocietypublishing.org/doi/10.1098/rs…

We developed a new dimensionality reduction method that allows for adaptive latent feature sharing, for capturing both common & rare features in the data in a parsimonious way. We show that it is capable of flexible structure discovery and dimension: jmlr.org/papers/volume2…

New in Cognitive Psychology, from @kasia_mojescik, @SamBerenz, @flaviadielle, @maureenritchey and @chrismbird: The Relationship Between Subjective Memory Experience and Objective Memory Performance Remains Stable Across the Lifespan doi.org/10.1525/collab…
