Hello world! 👋 We’re Minds, Machines, and Brains (MMB) 👤🤖🧠 a new open access journal from @mitpress.bsky.social exploring the principles of intelligence and cognition across natural and artificial minds. Submissions open this Fall! 🔗 direct.mit.edu/mmb

New paper out w/ Katherine Duncan and Morgan Barense! Why do some memories update when our expectations are violated, while others remain stable? What matters most is the strength of a memory at reactivation—not how old it is. And, I designed the cover! royalsocietypublishing.org/rstb/article...

Memory strength at reactivation, not memory age, governs prediction error-driven updating of naturalistic event memory

Abstract. Prediction error during memory reactivation is posited to be a key driver of memory updating. However, prediction error leads to varied memory ou

If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

Climbing fibers encode the gradient of a loss function for the cerebellum

Neurons in the brain are often many synapses away from motoneurons, yet if a movement results in error, each distant neuron needs a teacher that considers its specific contribution to production of th...

Preprint alert! 🚀 Spontaneous eye blinks are often treated as EEG artefacts. We show they can serve as temporal markers of internal attention, aligning with moments of attentional focusing in working memory. Check it out:

Spontaneous eye blinks as temporal markers of internal attention

Eye blinks are among the largest physiological artefacts in electroencephalography and are typically removed from the recordings. Yet their timing may carry information about cognition. Here, we asked...

Dear peer reviewers everywhere: sometimes we feel pressure to find issues with a submission as a demonstration of diligence. But we have to recognise this is a mistake: picking random and sometimes incoherent holes in research add confusion, generates unnecessary work and encourages defensive

Very excited to share our new review on C-HORSE, our model of the hippocampus! We think there is very encouraging alignment between C-HORSE proposals and the extant empirical literature, though we also note plenty of areas for further model development. royalsocietypublishing.org/rstb/article...

And for our own contribution to the theme issue: Oliver Warrington and I show that the dentate gyrus encodes prediction errors during learning of perceptual predictions. This finding complements our previous work showing a transition from errors to predictions during learning (Aitken & Kok 2022). 🧠🟦

The hippocampus sits at the interface of perception & memory, allowing us to link past, present, & future through its role in generating predictions. Excited to share this theme issue in @royalsociety.org's Philosophical Transactions B, co-edited with @barense.bsky.social & @mariamaly.bsky.social

Our paper "Neural timescales from a computational perspective" is finally out in @natneuro.nature.com: www.nature.com/articles/s41... We discuss how computational models and methods can distill empirical observations on neural timescales into quantitative, testable theories of brain computation.

A *super* exciting new paper from @lizsiefert.bsky.social!! Human hippocampal ripple rates track very closely with several indicators of low arousal, during both sleep and wake. This is probably the most compelling data I have ever been associated with.

Liz Siefert@lizsiefert.bsky.social · last mo.

New preprint! We show low arousal states promote hippocampal ripple genesis in sleep and wake. This bridges rodent work, where ripples predominate during sleep, with human studies reporting ripples during active behavior, identifying low arousal as a common mechanism www.biorxiv.org/content/10.6...

I've been told my discussion with NPR about US academics/scientists moving overseas will be on NPR later today on All Things Considered! Live broadcast 4-6pm Eastern. Don’t know when my segment will be within this, but tune in! Huge thanks to @npr.org for the opportunity to share my perspective.

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

The paper shows that high‑gamma field activity and local spiking are distinct. The “hashy” signal often treated as a proxy for spiking is partly generated by other biophysics like dendritic and network‑level currents, not just summed spikes. www.nature.com/articles/s41... #neuroscience

A brain–machine interface is used in monkeys to investigate the biophysical underpinnings of cortical high gamma-band activity, a signal that is often studied in the context of many brain functions.
