We are deeply saddened to share that Dr. Denise C. Park, founder of CVL, passed away on Sunday, Feb 1. A pioneering cognitive neuroscientist, mentor, & leader, Dr. Park shaped the study of memory, aging, & the brain. Read the full remembrance here: cvl.utdallas.edu/in-memory-of-dr-denise-c-park/
Finally: the fantastic #registeredreport from bsky-less Roni Tibon is out: www.nature.com/articles/s41... showing less difference between #episodic vs. #semantic #memory than one might have thought.
Proud to have contributed a tiny part to this great paper.
Over the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.
Last week to apply!
In a new paper, I delve into these two findings and muse on when prediction might help vs. hurt memory (and discuss why this matters for models of memory and the hippocampus). This is my first solo-author paper, and I had a lot of fun putting these ideas on paper! direct.mit.edu/opmi/article...
Interpreting EEG requires understanding how the skull smears electrical fields as they propagate from the cortex. I made a browser-based simulator for my EEG class to visualize how dipole depth/orientation change the topomap.

Can reward improve memory for what came before it? 🌟
In a registered report with @duncanlabuoft.bsky.social & @megschlichting.bsky.social, we reconcile mixed findings from past studies: reward retroactively boosts associative—but not item—memory, and only in reward-sensitive individuals!
Feeling incredibly grateful! Thank you to my examiners, Ed and Chris, for an engaging and insightful discussion about my work, and to my supervisor, Alexa, for her incredible support and guidance over the past four years. Excited for the next chapter as Dr. Zhang.
Important new resource for all Hippocampus lovers!👌👇
Ahem. Mental imagery (& imagery-critical) researchers should read this:

So happy to share our paper on the role of the hippocampus as a mismatch detector:
doi.org/10.1073/pnas...
We show that the hippocampus detects mismatches between ongoing experiences and episodic memories but not generalised schematic knowledge.

Does watching a movie over and over make events slower or faster in the brain? With Narjes Al-Zahli and @mariamaly.bsky.social we find that different regions actually change in different directions, e.g. visual regions show finer-scale event structure and STS shows coarser-scale structure!
New preprint from Yining Ding @liliand.bsky.social! People use semantic event knowledge and grouping to remember the temporal order of events.

Excited to share our new paper w/ @cibaker.bsky.social in @natcomms.nature.com linking active vision & memory!
We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. doi.org/10.1038/s414...

Cortico-hippocampal interactions underlie schema-supported memory encoding in older adults
New paper led by @shenyanghuang.bsky.social!
academic.oup.com/cercor/artic...
Older adults' memory benefits from richer semantic contexts. We found connectivity patterns supporting this semantic scaffolding.
I wrote an R package that creates standardized R project structures that are compliant with @mekline.bsky.social's psych-DS...ish.
It also creates additional features for reproducibility and teaching like a readme, license, .gitignore and Quarto templates
+ can validate existing projects
I'm not a big poster, but had to share how proud I am of my postdoc, Lauri Gurguryan, for submitting the FIRST paper from my lab 🎉
Here, we ask a classic ? Do short- and long-term memory rely on separate or shared underlying stores

Seems as good a time as any to re-share the "OpenLists" collection - an openly accessible set of lists of available resources in / for Cognitive Neuroscience!
Includes open M/EEG & iEEG datasets & open software / analysis tools, and resources for DSP, Python, git, etc:

Dream start for database that aims to improve our understanding of conscious experience in sleep

Excited to share my first fMRI paper in @pnas.org We found that suppressing the encoding of one event can strengthen the neural representation of the next in CA1, and bias retrieval-related neural restatement away from suppressed information. www.pnas.org/doi/10.1073/...
Successful prediction of the future enhances encoding of the present.
I am so delighted that this work found a wonderful home at Open Mind. The peer review journey was a rollercoaster but it *greatly* improved the paper.

This is genuinely one of the best explanations I've ever read about permutation testing! 🦙 www.jwilber.me/permutationt...
Thank you @jwilber.bsky.social for breaking this down so clearly
This was a fun paper to write, and one that fits nicely with some recent work I've been doing on the role of counterfactual simulation in memory encoding. link.springer.com/article/10.3...
Looking at Van Gogh’s Starry Night, we see not only its content (a French village beneath a night sky) but also its *style*. How does that work? How do we see style?
In @nathumbehav.nature.com, @chazfirestone.bsky.social & I take an experimental approach to style perception! osf.io/preprints/ps...
After you fall asleep in the sleep lab, we can decide what you dream about — as Karen Konkoly showed in her PhD work and just published in this new paper:

Excited to share our new publication on the influence of odor perception on memory. Congratulations to @joantarridav.bsky.social for initiating this fascinating line of research in our lab.
Very excited about this work and very proud of @xiongbowu.bsky.social who did it all:
Based on 4 independent data sets (incl. EEG/iEEG, eye tracking, gaze manipulation & memory), we advocate for a new perspective on the function of the brain's dominant rhythm 🧠
