There is growing interest in how cognitive control may improve value-based decision making.
However, we find that a recent paper overestimated the role of control in their task, leading to erroneous interpretations of dACC recordings.

How can we behave effectively in the future when, right now, we don't know what we'll need?
Out today in @nathumbehav.nature.com , @marcelomattar.bsky.social and I find that people solve this by using episodic memory.

This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay!

I've added lots of fun interactive demos of chatbots and NLP techniques that let students dig into the approaches.

We show that the HPC supports coincidence detection across VTA and lPFC in service of novelty-evoked invigoration. Stay-tuned for how these circuits are altered in psychosis risk.

This is a great summary of the study and a broader discussion of what brain research can teach us about important developmental phases.
After analyzing nearly 4,000 scans from ages 0–90, researchers found major structural shifts at ages 9, 32, 66, and 83 — dividing life into five distinct phases.
This is a great summary of the study and a broader discussion of what brain research can teach us about important developmental phases.
my lab will develop scalable models/theories of human behavior, focused on memory and perception
currently recruiting PhD students in psychology, neuroscience, & computer science!
reach out if you're interested 😊

Faster contextual changes are associated with faster drift in hippocampal activity and reduced temporal clustering in recalled memories.
