Awesome, congrats!!

A 2024 study found that ants best humans at tests of collective intelligence.

Linking it to our previous crow brain anatomy study (Moll et al., 2025, JCN): Our behavioral paradigm offers a scaffold for future studies investigating neuronal correlates of corvid tool use in the avian general motor system and beyond.

At the start of each trial, when the crows pulled the stick from the holder, the stick was often misaligned with the beak. In these cases, the initial pull was followed by brief tosses—momentary re-leases and re-grasps of the stick—to adjust its orientation within the beak and achieve a better grip.

Trained crows dexterously corrected errors when the tool’s working end lost control over the target.

DeepLabCut pose estimation (@trackingactions.bsky.social) revealed high intitial motor variability, which is essenatial for motor learning (Dhawale et al., 2017, Annu. Rev. Neurosci.).

New paper on precise tool use learning in carrion crows @currentbiology.bsky.social. We show that—like New Caledonian crows—expert carrion crows pay close attention to the working end of their tool, suggesting tool integration into their peripersonal space. 🧵 & vids! 👇

Cool new paper on how neurons in my favorite bird's brain encode time. Congrats Millie and Max!! @milliejohnston.bsky.social , @crowbrain.bsky.social

Exploring Neural Dynamics in the Auditory Telencephalon of Crows Using Functional Ultrasound Imaging Crows, renowned for advanced cognitive abilities and vocal communication, rely on intricate auditory systems. While the neuroanatomy of corvid auditory pathways is partially explored, the underlying n...

Cool new method (functional ultrasound imaging) now established in the crow by @daliao.bsky.social and colleagues:

Amazing meeting with amazing people!

Did complex song and dance co-evolve with brain size in the birds-of-paradise (Aves: Paradisaeidae)? Abstract. Complex signaling behaviors, such as avian song and courtship displays, have been associated with increases in both absolute and relative brain s

Our paper on brain size evolution in birds of paradise was recently accepted!

In brief:
•BoPs have big brains, comparable to those of medium-sized corvids
•Neither absolute nor relative brain size appears to have co-evolved with display complexity

My latest Aronov lab paper is now published @Nature!

When a chickadee looks at a distant location, the same place cells activate as if it were actually there 👁️

The hippocampus encodes where the bird is looking, AND what it expects to see next -- enabling spatial reasoning from afar

Our first look at midbrain PAG’s role in singing mouse vocal control. When near each other, these mice produce two divergent vocal modes. Same circuits for USVs and Songs—or different ones? Bets were made..some of us bought beers for others! Led by @xmikezheng20.bsky.social & Clifford Harpole. 👇🏽

Convergent vocal representations in parrot and human forebrain motor networks - Nature Using advanced brain-recording techniques, parrots were found to have a brain organization for vocal control similar to humans, making them an important model for studying speech and for developing potential treatments for communication disorders.

Dual neuromodulatory dynamics underlie birdsong learning - Nature Dopamine release in the basal ganglia of the zebra finch is driven by neurons associated with reinforcement learning and by cholinergic signalling, and tracks performance quality during long-term lear...

Proud to have contributed to @jiaxuanqi.bsky.social's masterpiece out @nature.com! She shows that dopamine transients track the learned quality of song during juvenile learning and that dopamine release is driven not just by VTA firing, but by a local cholinergic mechanism! (1/x)

Natural behaviour is learned through dopamine-mediated reinforcement - Nature Studies in zebra finches show that dopamine has a key role as a reinforcement signal in the trial-and-error process of learning that underlies complex natural behaviours.

Excited to share our latest work! It’s been a great experience working on this (including building a whole new lab!) 😊

Exploring Anatomical Links Between the Crow's Nidopallium Caudolaterale and Its Song System The crow's nidopallium caudolaterale (NCL) projects densely to the dorsal intermediate arcopallium (AID) and the striatum, paralleling important song system pathways. Connections from the magnocellul...

Now published in JCN: "Exploring Anatomical Links Between the Crow's Nidopallium Caudolaterale and Its Song System"

In crows (which are songbirds!), we show that the song system is paralleled by the 'general motor system' (cf. Feenders, 2008; Farries, 2001).
