The Memory Disorders Research Society (MDRS) is seeking nominations for new members. Self-nominations are welcome! The society is broadly focused on memory research; not just disorders. Here is the nomination form, which includes info about eligibility criteria: forms.gle/Qn7mchoPpaqL...

Happy to share some of the work done in our lab in this mega-thread of nine (!) papers/preprints (+1 sneak peek) from the last six months. Here goes (in no particular order)! **Please repost** and let me know if you need access to any of the PDFs! #sleeppeeps #sleep #neuroscience 1/12

🚨NEW PREPRINT (w/ Fleming Peck & Hongjing Lu) "Spontaneous emergence of context-dependent statistical learning in humans and neural networks" We are constantly predicting what will happen next. Yet the same cue can lead to different predictions depending on context. How might this work...? 🧵1/8

My favorite conference is the Memory Disorders Research Society meeting. It's a delightful community: top-notch research & wonderful people who have been so supportive in my career. Want to join? Nominations for membership (including self-nominations) are open until April 9! Form at the top👇🏼

MDRS

MDRS is a professional society dedicated to the study of memory. Members engage in basic and clinical research into how memory works and why it fails.

The Memory Disorders Research Society (MDRS) has extended its deadline in seeking nominations for new members to next Wednesday (4/9)! Self-nominations welcome. Feel free to DM me if you have questions about the society or the membership process. Application link: docs.google.com/forms/d/e/1F...

Excited to share this new preprint, along with an explainer thread written by my talented collaborator Michal Ramot. Are face perception and face memory fundamentally independent processes, or are they overlapping and impossible to disentangle? 🧵 www.biorxiv.org/content/10.1...

Behavioural separation of face memory and face perception

A long-standing debate in neuropsychology concerns whether perception and memory function as independent systems or interact to support cognition. To investigate this, we developed the Face Memory and...

Still one month left to apply for the tenure-track faculty position in "Measurement Issues in Complex Data Structures" in the UCLA Dept of Psychology. The scope is broad, but includes methodologists working with brain data (fMRI, EEG, cellular neurophysiology/imaging). recruit.apo.ucla.edu/JPF09885

🧠👁️ Our MindEye2 preprint is out! We reconstruct seen images from fMRI activity using only 1 hour of training data. This is possible by first pretraining a shared-subject model using other people's data, and then fine-tuning on a held-out subject with only 1 hr of data. arxiv.org/abs/2403.11207

In case you missed @crewalsh.bsky.social’s thread on the other network, I wanted to share our latest paper here. We used a novel approach to examine the representational underpinnings of the testing effect and the bidirectional interplay of episodic & semantic memory. www.nature.com/articles/s41...

How does episodic learning affect the structure of semantic memory? Episodic learning pulls associated words together in semantic space. A cue word's semantic representation moves closer to the target word. Clever use of behavior to understand memory representations! By Walsh & @rissman.bsky.social

Behavioral representational similarity analysis reveals how episodic learning is influenced by and r...

Pre-existing semantic knowledge provides an organizational structure for episodic memories. Here, the authors show that episodic learning systematically shapes this semantic space depending on how lea...

Hippocampal neurons code individual episodic memories in humans. The neurons don't code for a particular element in the episode (e.g., concept or time). They code for the conjunction of the different elements. #neuroscience #psychology #PsychSciSky #NeuroSkyence www.nature.com/articles/s41...

Hippocampal neurons code individual episodic memories in humans - Nature Human Behaviour

Kolibius et al. show that individual neurons in the human hippocampus code for particular episodic memories.

Every year when I teach about fMRI, I show this same crappy 1990’s era illustration of the subject setup. Is this really the best we have?? If you have a better figure, please send it my way!

Lab outing to celebrate my grad student Catherine Walsh’s (left) successful defense of her dissertation “Decomposing complex cognitive processes precious to understand individual differences in behavior”. She’s now off to NIMH to work with Peter Bandettini’s group. So proud of her accomplishments!
