This one focuses on modern art, not interdisciplinary connections, but it’s a classic (and, I think, graphically excellent).

First whole-brain recording of social sound processing in a vertebrate. Surprises start in the hindbrain; thalamus gates conspecific calls; male and female brains diverge downstream. Work by @joerghenninger.bsky.social, @mh123.bsky.social sky.social and team. www.biorxiv.org/content/10.6...

When a fly lands on your arm, how does your nervous system decide where to swat?

By reconstructing tactile axons in a Drosophila connectome, we found a leg somatotopic map and downstream circuits that sample the map to initiate targeted grooming

Using our bee-tracking drone, we discovered that honey bees 🐝 have highly precise and individual routes. Now published at @currentbiology.bsky.social : doi.org/10.1016/j.cu...

A remarkable discovery: motor sequences in zebra finch song are generated intrinsically within HVC. Beautiful!

Feedback control of random networks as a model of flexible motor cortical dynamics across tasks Kalidindi and Crevecoeur develop a computational framework linking feedback-controlled networks to limb dynamics. They demonstrate that optimal control of fixed network reproduces key motor cortical d...

Some scientists used to think that birds are just kind of stupid. In the 1960s, the neuroanatomist Harvey Karten’s research into avian neural circuits changed how the field viewed bird intelligence. www.quantamagazine.org/intelligence...

Primate dexterous hand movements are controlled by functionally distinct premotoneuronal systems Distinct spinal and cortical pathways coordinate muscle synergies and fine control to support primate dexterous hand movements.

Our paper is out in Science Advances!
What makes primate hands so dexterous?
We show that evolutionarily distinct spinal and cortical pathways work together to balance stability and flexibility, supporting remarkable primate hand control.

New paper alert! 🚨

We found that the brain's compass is remarkably stable at two scales

1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit

This may be key to how the brain aligns its other maps.

From Chand: “of potential interest”. Our lab’s first dataset! Tian and friends used Neuropixels to record from 7,500 units across DLPFC and PMd to show how contextual decision making (specifically, XOR computation) occurs and how this differs by location in DLPFC and between areas.

This is a catastrophic unforced error.

It was quite something to hear @ohsunews.bsky.social President Shereef Elnahal equate the shambolic lies of fringe groups (“others”) with the heartfelt & credible testimony of the scientists & veterinarians in his employ.

“Teammates” don’t support rivals.

“A sanctuary is not a strategy. It is a capitulation to fear and the political pressure that ignores scientific reality”

Well said @vincentcostaphd.bsky.social

Neuro’s ark: Understanding fast foraging with star-nosed moles “MacArthur genius” Kenneth Catania outlined the physiology behind the moles’ stellar foraging skills two decades ago. Next, he wants to better characterize their food-seeking behavior.

Kenneth Catania spoke with @thetransmitter.bsky.social about how the specialized snout of the star-nosed mole allows for high-speed foraging and underscores the importance of studying behavior alongside anatomy.

We have updated this preprint. I think the deeper dive that @mkashefi.bsky.social has done on the 'shift' condition-independent signal is particularly interesting. www.biorxiv.org/content/10.1...

Beautiful work - congrats!!!

Where does learning through imitation happen in the brain?

In juvenile zebra finches, we pinpoint a synaptic locus of song learning in a cortico-basal ganglia circuit and leverage this localization to measure the timescale of consolidation and make birds learn faster! #neuroskyence (1/14)

Dynamic engagement of the motor cortex in controlling movement Neural circuits do not contribute equally or continuously to behavior. In mice, the motor cortex can be essential or dispensable for movement in different contexts, but how it is dynamically recruited...

Very excited to share a new preprint - my first paper in the @mikeeconomo.bsky.social lab where we asked when and why the motor cortex is recruited for movement control:🧠👇https://www.biorxiv.org/content/10.64898/2026.01.13.699314v1

We had a lot of fun working on this project (led by Itzel Ishida, not on bluesky). Some interesting highlights from the paper -

Here's another, showing raw voltage throughout the dendritic tree, the virtual reality location of the animal, the mouse-eye view, and the voltage at the neuron's soma.

What is the computational role of dendritic excitations? Byung Hun Lee and team mapped voltage dynamics throughout the dendritic trees of CA1 pyramidal neurons in mice navigating in virtual reality. www.biorxiv.org/content/10.6...
