A synaptic locus of song learning Learning by imitation is the foundation for verbal and musical expression, but its underlying neural basis remains obscure. A juvenile male zebra finch imitates the multisyllabic song of an adult tutor in a process that depends on a song-specialized cortico-basal ganglia circuit, affording a powerful system to identify the synaptic substrates of imitative motor learning. Plasticity at a particular set of cortico-basal ganglia synapses is hypothesized to drive rapid learning-related changes in song before these changes are subsequently consolidated in downstream circuits. Nevertheless, this hypothesis is untested and the synaptic locus where learning initially occurs is unknown. By combining a computational framework to quantify song learning with synapse-specific optogenetic and chemogenetic manipulations within and directly downstream of the cortico-basal ganglia circuit, we identified the specific cortico-basal ganglia synapses that drive the acquisition and expression of rapid vocal changes during juvenile song learning and characterized the hours-long timescale over which these changes consolidate. Furthermore, transiently augmenting postsynaptic activity in the basal ganglia briefly accelerates learning rates and persistently alters song, demonstrating a direct link between basal ganglia activity and rapid learning. These results localize the specific cortico-basal ganglia synapses that enable a juvenile songbird to learn to sing and reveal the circuit logic and behavioral timescales of this imitative learning paradigm. ### Competing Interest Statement The authors have declared no competing interest. National Institutes of Health, K99 NS144525 (DCS), F32 MH132152 (DCS), F31 HD098772 (SB), R01 NS099288 (RM), RF1 NS118424 (RM and JP)

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)

Excited to share @rbrianroome.bsky.social β€˜s beautiful paper on development of the dorsal horn of the mouse spinal cord @science.org

This is how the anatomical organization and cell types that process pain, touch, body position and more are laid down.
