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).

🧠👁️ 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.

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.

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.

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.

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!
