New preprint! TLDR: We mapped the genetic architecture of neonatal vocalization in deer mice, and found candidate genes expressed in the cerebellum that could be contributing to the evolution of temporal structure in infant cries #Bioacoustics #neuroskyence www.biorxiv.org/content/10.6...

The Genetic Architecture of Neonatal Deer Mouse Cries Implicates the Cerebellum in the Temporal Control of an Infant Social Behavior

Vocal communication is a conserved vertebrate social behavior that begins at birth with the cries of infants. These neonatal vocal signals vary across contexts to elicit parental care that matches inf...

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 Shareable link: rdcu.be/fiyrS

More control wires enable finer control. The Banerjee lab's findings on the neuroanatomical underpinnings of vocal dexterity neatly tie in with a recurring motif in brain evolution: pre-existing pathways can be selectively expanded to increase sensorimotor control and expand behavioral repertoires.

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)

1/4 New preprint! We designed an open-source system for auditory brainstem response (ABR), a research & clinical auditory test. Costs $400 to build (vs $10K to buy a proprietary one) and works great! All open-source if you want to make one for your lab or classroom. www.biorxiv.org/content/10.6...

As a longtime fan of cool papers in @currentbiology.bsky.social, I am really thrilled to see this out! This study sets the stage for understanding the origins of novel (vocal) behaviors. Big shout out to the main architects of this work @xmikezheng20.bsky.social and @cliffscience.bsky.social
