🚨 California and Hawaii under tsunami watch after 8.7M quake in Eastern Russia.

Tsunami Warning

Tsunami Warning – 7/30, 9:40am
The Tsunami Advisory has been upgraded to a Tsunami Warning. Waves of up to 3m are expected. Those near coastal areas, rivers, or lakes should evacuate to higher ground immediately. #tsunami

Evolutionary trade-off between vocal tract and testes dimensions in howler monkeys - PubMed Males often face a trade-off between investments in precopulatory and postcopulatory traits [1], particularly when male-male contest competition determines access to mates [2]. To date, studies of pre...

The point is, the monkeys making the loudest noise have the smallest balls.

Dem leadership should appoint an official Alt Press Secretary to give briefings after every one that Karoline Leavett does and just break them down lie by lie

maybe THAT’S the job we give Colbert 😂

An exciting collaboration is underway. @thetransmitter.bsky.social is partnering with @neuromatch.bsky.social to serve the computational neuroscience community and help connect neuroscientists across all career stages.

Cooperative thalamocortical circuit mechanism for sensory prediction errors - Nature Experiments in mice show that a cortico-thalamic circuit generates prediction-error signals in primary visual cortex that amplify visual input that deviates from animals’ expectations.

Pairs well with www.nature.com/articles/s41...

“Our results indicate that individual V1 neurons do not signal how the actual visual input deviates from the animal’s predictions, as postulated within the predictive coding framework”

Thrilling to see a major theory get tested!

Exciting new preprint from the lab: “Adopting a human developmental visual diet yields robust, shape-based AI vision”. A most wonderful case where brain inspiration massively improved AI solutions.

We show that scene affordances—what you can do in a space—shape how we perceive and categorize scenes. This shapes your similarity preferences, predicts your categorization false alarms, and even alters neural representations. 🧵👇

Spared spatial imagery solves the puzzle of aphantasia

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).

fMRI must break out of its silo We need to develop research programs that link phenomena across levels, from genes and molecules to cells, circuits, networks and behavior.

ICYMI: “For fMRI to meaningfully contribute to progress in neuroscience, we need to develop research programs that link phenomena across levels,” writes Avram Holmes @avramholmes.bsky.social.

Another great article from @thetransmitter.bsky.social and Laura Lewis, who has been working painstakingly over the last few years to help ramp up the spatiotemporal resolution of fMRI so that we can really start to dig into whole-brain signals in vivo.

fMRI can do more than you think Advances in brain imaging technology provide new and different information about the brain.

ICYMI: Recent technological advances in functional MRI provide a range of new information about brain physiology. Collaboration between engineers and neuroscientists will help maximize these gains, writes Laura Lewis.

New preprint!

Why are long-range connectomic interactions in the cortex dominant in shaping dynamics in some experiments but apparently negligible in others?

We (w/ R Maran, @elimuller.bsky.social) address this question by studying a new hybrid model of cortical dynamics.

Fantastic article from one of the leaders of the burgeoning field or layer-resolved functional MRI. A pleasure to read!

Imaging cortical layers to understand brain as network organ This spatial scale, bridging cells and brain areas, has been overlooked in human brain research. But advances in fMRI technology are changing that.

ICYMI: In this essay for our Future of fMRI series, Laurentius Huber @layerfmri.bsky.social explains how new advances in functional MRI could help to connect cells and brain areas at the mesoscopic scale.

The diversity of methods we use to probe the brain (epistemologies) naturally leads to clashes in our theories of how the brain works (ontologies). So how do we reconcile this divide and grow into a more unified neuroscience? Here is our take:

Oh cool. I really love Matthew Larkum's work on the neural substrates of consciousness too, though he and I have not yet had a deep discussion about intralaminar thalamus just yet ;)
