New paper from the lab now out online! @changrun-huang.bsky.social asked whether people use informative pre-cues to up-regulate cognitive control in the spatial Stroop task. Surprisingly, they do not, and we rule out some possible reasons why. Enjoy!

Neuroscience has a species problem If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle.

The biggest problem holding neuroscience back right now isn’t data or tools, thanks in large part to the BRAIN Initiative.

It’s fragmentation across species. I wrote this to hopefully spark discussion around an issue that can only be solved as a community👇

Duration between rewards controls the rate of behavioral and dopaminergic learning - Nature Neuroscience Cue–reward learning rate scales proportionally with the time between rewards. Consequently, learning over a fixed duration is independent of the number of trials. This challenges trial-based dopamine ...

Very excited to post our paper led by @daburke.bsky.social www.nature.com/articles/s41... where we uncover a simple mathematical rule underlying how brains learn that a cue predicts a reward. 1/26

Parkinson’s disease as a somato-cognitive action network disorder - Nature The substantia nigra and all Parkinson’s disease deep-brain stimulation targets are selectively connected to the somato-cognitive action network rather than to effector-specific motor regions.

In case this important point gets overlooked: along with our Nature paper, we’ve publicly released two large and scarce datasets—PIPD and PIET. IMHO, these are the best open Parkinson's and Tremor datasets available to date.

A unifying account of replay as context-driven memory reactivation A context-driven memory model simulates a wide range of characteristics of waking and sleeping hippocampal replay, providing a new account of how and why replay occurs.

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!!

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

Agency alters memory organization during free recall - PubMed This study examined how agentic decisions in the absence of explicit rewards influence memory organization. Participants studied lists of items to assign as gifts to two characters-either choosing freely (Choice group) or following instructions (Fixed group). During free recall, participants in the …

Agency reorganizes memory around relevant decisions. This was collaboration the deeply missed Sarah DuBrow and steer-headed by our grad students @lindsayrait.bsky.social and Elizabeth Horwath.

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience

fMRI signals “up,” but neural metabolism might be going “down.”

In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes.

Cover of this week's Nature showing a brain rendering

Cover caption from the journal:
Brain development:
Our ability to process information into complex emotions, behaviours and decisions relies on the rich diversity of cell types that make up the human brain. Uncovering the molecular and cellular events that take place during brain development could reveal not only the mechanisms that give rise to this diversity but also shed light on how this process might go awry in neurodevelopmental disorders such as autism and schizophrenia. In this week’s issue, the BRAIN Initiative Cell Atlas Network (BICAN) builds on its previous work creating atlases of cell types in the adult mouse, non-human primate (NHP) and human brains to present cell-type atlases of the developing human, mouse and NHP brains. Across a suite of papers, nine of which are published in Nature, the researchers uncover the complex programs through which cell types emerge during brain development in humans and animals, revealing both the shared and unique features of the human brain. The latest work, along with future research directions, is summed up in a Perspective article by Tomasz Nowakowski and colleagues
