New preprint led by @rgast.bsky.social- part 1 of Richard's ongoing effort to make a better firing rate model: developing mean-field models that can be fit to biological data to capture both the dynamics of neural populations and the underlying physiological heterogeneity that sculpt those dynamics.

The Ott-Antonsen ansatz revolutionized our understanding of coupled oscillator systems with heterogeneous oscillators. We developed a multi-ensemble method that increases the applicability of the OA ansatz to empirical data substantially arxiv.org/abs/2607.09516, as we demonstrate on neural data.

Protip: review the paper, not the authors. A paper is not a grant proposal and you don't need to critique the PI, just the work. It's actually easy to not mention the authors at all. Instead of "the authors should...", just say "the work should address..." or "the paper would be improved by..."

If you don't like a paper, it is obviously totally fine to point out the issues. But please do NOT make egregious and unpleasant comments about the first author's qualifications. A first author who is usually a trainee. Beyond inappropriate and unprofessional.

my first response was wtf. but then my second was oh it's procedural memory, nvm. HM improved at procedural tasks repeated across days, he just couldn't remember why it seemed to getting easier

"Replay occurs in the dorsal striatum during offline consolidation of a procedural memory in mice" - even with total hippocampal lesions pubmed.ncbi.nlm.nih.gov/42493550/ It looks like memory replay is a general capability of the brain - not a special feature of the hippocampus!

Happy to say our head-direction-cell-in-3D is finally out! doi.org/10.1038/s420... Confirms that the brain's compass uses a dual-axis rule (like an iphone does) to maintain a constant estimate of horizontal heading even when the head is not horizontal. Blogpost explanation here: shorturl.at/9VdGM

How the brain adapts its 2D compass for a 3D world

The brain’s neural compass seems 2D, detecting only left and right head-turns. However, if the head is tilted in 3D, its rotation around the vertical axis also covertly changes its horizontal facing ...

Academics: What's a journal in your field that's great? I feel like they are a dwindling breed. Criteria: (1) No APC. Supports green or diamond OA. (2) High-quality and relatively fast peer review. (3) Editors who provide real curational value and exercise purposeful agency in the decision process.

We've now highlighted all our amazing confirmed keynote speakers! Please sign up to our email list as this will be the main way we will communicate. Stay tuned for news about submissions, registration, and lots more! icom-memory.org #neuroskyence #psychscisky #cognition #ICOM2027 #philosophysky 🧪

One faculty ad, 200 applicants, 600 papers before the first shortlist. Nobody can read that, so metrics do the reducing — and slowly a committee stops reading at all. An essay on what we lose when judgement is handed to citation counts and h-indices. 🧵 academicrenewal.substack.com/p/when-acade...

When academics stop reading

Metrics can help decide where to look, but they turn dangerous when they replace contact with the work itself.

Every day, our brains arbitrate between competing memories and motivations. This ability allows us to flexibly adapt our behavior as the world around us changes. But how does the brain actually do it? Our new study sheds light on this! www.cell.com/current-biol...

The prelimbic cortex arbitrates memory-guided conflict resolution

Caban-Murillo et al. show that, during approach-avoidance conflict, prelimbic cortex ensembles are recruited to represent reward and punishment through distinct network patterns. Both ensembles are ne...

We found that activity covaried with inferred gaze behavior throughout the brain, spanning the cerebral cortex and cerebellum, and involving many regions associated with vision. The eyes were closed and people were sleeping! 4/8
