In a new study published in @currentbiology.bsky.social, researchers uncover how a dietary shift may have set the stage for one of nature’s most spectacular phenomena: the elaborate courtship displays of manakins.

🚨 New paper in @nature.com

We asked why two hippocampal areas with very different anatomy, CA3 and CA1, often seem to code space so similarly?

By recording bats flying up to 200m, we found that the difference was hidden by scale!

Sparse-to-dense coding transformation between hippocampal areas CA3 and CA1 - Nature
The hippocampus exhibits a CA3-to-CA1 coding transformation that combines fast learning with an efficient, compressed neural code.

Where, exactly, does learning happen in the brain?

Out today in @nature.com, we identify a synaptic locus of birdsong learning and show that the circuit can be tuned to make birds learn faster - but at a cost. Read on👇 #neuroskyence 🧪 #prattle 💬 #bioacoustics

In this beautiful paper from the Baier lab, authors show that cichlid fish show innate nest-building behaviors, but they are refined over time as animals learn to improve their nest! Additionally, they find brain activity in a region homologous to the hippocampus. 🐠🧠 www.cell.com/current-biol...

Grätsch et al. examine nest-building behavior in the shell-dwelling cichlid Lamprologus ocellatus. Nest building follows a stereotyped sequence of innate behavioral motifs that improve with experience...

Exciting new research published in @currentbiology.bsky.social by our guest scientist and former group leader @jmrko.bsky.social. The study highlights insights from connectomics research in songbirds. „Tunneling neurons“ open new perspectives on how adult neural circuits may regenerate.

🐟+🐚 =🏠 Shell-dwelling cichlids are true underwater architects, instinctively transforming empty snail shells into protective nests. New research shows: They improve with practice, remember what they learned, and adapt to unusual conditions.

How do fish localize sound without interaural cues? @johve.bsky.social et al. found a behavioral algorithm for directional hearing that predicts behavior from a pressure/motion phase comparison and accounts for how this relationship varies with distance. www.cell.com/current-biol...
An algorithm underlying directional hearing in fish
Veith et al. show how a fish—Danionella cerebrum—can reliably startle away from sound. It uses the relative phase between particle motion and pressure to infer the direction of sound. This sensorimoto...

Even innate vocal behaviors can be socially flexible. In zebra finches, replies to contact calls are faster and more reliable when the caller is familiar than when hearing strangers.
