We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor? www.biorxiv.org/content/10.6...

Thank you for having me on BrainInspired, Paul @braininspired.bsky.social! It was such an honor to be on my favorite show—a rare place where we can leisurely talk about manifolds, latent circuits, power laws, and other esoteric ideas, and still be taken seriously in knowing they are all real.

Department of Psychological & Brain Sciences at Johns Hopkins is inviting applications for 3 open-rank tenured/tenure-track positions in (1) Behavioral Neuroscience, (2) Cognitive Neuroscience, and (3) Cognitive Psychology. pbs.jhu.edu/about/jobs/

Birds are both intelligent and incredibly agile, yet they are quite small. How do they achieve this with their little brains? They have twice as many neurons per brain mass than mammals, including primates. www.pnas.org/doi/abs/10.1...

I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time! www.biorxiv.org/content/10.1...

Thanks to @pessoabrain.bsky.social and @thetransmitter.bsky.social for featuring our paper and to @aliyarumana.bsky.social and Peter Tse for engaging so generously with the ideas! 😊 www.thetransmitter.org/the-big-pict...

I am excited to announce that the Johns Hopkins University Solomon H. Snyder Department has become an interdivisional department between the School of Medicine and the Krieger School of Arts and Sciences, unifying neuroscience research and education across the university. hub.jhu.edu/2025/09/15/j...

How does the brain decide? 🧠 Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc. After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up. rdcu.be/eGUrv

Great to have another paper with @chazfirestone.bsky.social @ianbphillips.bsky.social and the brilliant Hanbei Zhou out! In this paper we demonstrate that stimuli within events are perceived further apart in time — an event-based analog of “object-based warping”. psycnet.apa.org/record/2026-...

It was an honor to write this, but also great fun. A chance to look back at the classics, and think about the path forward. #Physics is a beautiful human endeavor. journals.aps.org/prxlife/abst...

Neural manifold properties can help us understand how animal brains deal with competing and multifaceted information, execute flexible behaviors and reuse common computations, writes @mattperich.bsky.social. #neuroskyence www.thetransmitter.org/neural-dynam...

If you’ve ever tried to cram for an exam, you know that it’s easier to memorize something if you learn the information in shorter, spaced-out sessions. These dynamics are as relevant to each individual cell’s existence as they are to ours. Claire Evans reports: www.quantamagazine.org/what-can-a-c...

Happy 107th Birthday, Brenda Milner! Her contributions to neuropsychology shaped the way we understand the human brain. From surviving two world wars and two pandemics, to paving the way for future generations of researchers, Milner’s legacy continues. @mcgill.ca @cusm-muhc.bsky.social

In this “Brain Inspired” episode, Paul Middlebrooks and Xiao-Jing Wang discuss how neuroscience has changed over the past 50 years, and how Wang believes modern theoretical tools will lead to a new era of “cross-levels mechanistic understanding.” Listen now: www.thetransmitter.org/brain-inspir...

Domestication of dogs induced the expansion of the neocortex and reduction in size of subcortical structures: www.jneurosci.org/content/45/2... Reminds me of a theory I once heard that humans basically self-domesticated themselves.

Thrilled to see our TinyRNN paper in @nature! We show how tiny RNNs predict choices of individual subjects accurately while staying fully interpretable. This approach can transform how we model cognitive processes in both healthy and disordered decisions. doi.org/10.1038/s415...

The neurons that encode sequential information into working memory do not fire in that same order during recall, a finding that is at odds with a long-standing theory. Read more in this month’s Null and Noteworthy. By @ldattaro.bsky.social #neuroskyence www.thetransmitter.org/null-and-not...

Short new piece on aphantasia just out in TiCS: www.sciencedirect.com/science/arti... Key idea: aphantasia often involves a lack of *visual-object* imagery (explaining subjective reports & objective correlates) but selectively spared *spatial* imagery (explaining preserved task performance).

Wonderful to see this piece out! I really think we as a field are converging on a unified account of the hippocampus as a modality agnostic, task-relevant, sequence prediction machine. I bet that within the next decade we will have a complete computational model of the hippocampus. 🧠📈 🧪

Out today in @nature.com: we show that individual neurons have diverse tuning to a decision variable computed by the entire population, revealing a unifying geometric principle for the encoding of sensory and dynamic cognitive variables. www.nature.com/articles/s41...

Delighted to be the opening chapter of this brilliantly conceived (and beautifully covered!) new interdisciplinary collection on Space, Time, and Memory edited by the wonderful Lynn Nadel and Sara Aronowitz. Even better, the whole thing is free to download here: library.oapen.org/bitstream/ha...

i have uploaded this preprint a while back, but hadn't promoted it directly here. in this piece i explain why i can no longer recommend trainees to participate in my former home field. The End of Conscioussness - osf.io/preprints/ps... but i've learned a lot. thank you for everything. 🧠📈

Amidst all the arguments, its important to remember science is all about love … #AGIComics

Thrilled to share our work in ScienceAdvances: “Chronic ethanol exposure produces sex-dependent impairments in value computations in the striatum.” Huge thanks to Tricia @janaklab.bsky.social, Daeyeol @ungteoriz.bsky.social, Angela, and my friend Robin! www.science.org/doi/full/10....

How do temporal & spatial scales of resting-state fMRI in human cortex change with age? Research at Neurogazer (company I co-founded) found that they decrease throughout lifespan in most cortical areas but increase until the age of ~12 in the prefrontal cortex. www.biorxiv.org/content/10.1...

We have lost a legend. Yesterday morning, I received the devastating news that Kanzi, the world’s most famous bonobo, died unexpectedly the day before, in the company of his bonobo family at Ape Initiative, in Des Moines, Iowa. I've written here about this tremendous loss. We will miss him dearly.

Time-domain brain: temporal mechanisms for brain functions using time-delay nets, holographic processes, radio communications, and emergent oscillatory sequences www.frontiersin.org/journals/com... #neuroscience

Our memories are not encoded with timestamps. How do we reconstruct the passage of time from our memories? In a new paper (accepted at Psych Science) @samiyousif.bsky.social and I demonstrate a powerful illusion of time that results from repeated experience osf.io/preprints/ps...

Sharing some positivity here! Grateful for the opportunity to connect with old friends and to make new ones at JHU. Thank you @hyungbaekwon.bsky.social for inviting me!
