How does a brainlearn to sing?

We study how brains learn complex vocal behavior, build AI that reveals the structure of animal communication, and engineer new interfaces to the nervous system.

Canary used in birdsong research01

Birdsong & neural computation

We use songbirds to uncover how biological neural networks learn and produce complex, precisely timed behavior.

Our experiments span vocal learning, neural circuit dynamics, electrophysiology, and cellular-scale imaging in singing birds.

Machine-learning analysis from the Gardner Lab02

AI for animal communication

We build self-supervised models at the natural timescale of birdsong, allowing machines to discover, parse, and compare vocal units with very little labeled data.

SongMAE combines 5 ms representations with spatial masking to resolve individual syllables while retaining strong species-classification and detection capabilities.

Neural interface developed by the Gardner Lab03

New neural interfaces

We build miniature, long-lived interfaces for recording and stimulating the nervous system.

Projects include direct laser-write 3D printing, thin-film ultramicroelectrodes, miniature microscopes, and chronic peripheral nerve interfaces.

SongMAE → circuit discovery

SongMAE helps us see the structure of song. This work asks which neural circuits keep that structure moving.

How does the brain keep a learned song on time?

Canary song depends not only on producing the right syllables, but on knowing when to move to the next one. By pairing targeted neural-circuit lesions with high-throughput TweetyBERT analysis of thousands of songs, we found that disruptions involving medial Anterior Forebrain Pathway circuitry destabilized phrase timing. Affected birds developed sustained, prolonged, and variable repetition of particular syllables, revealing an ongoing role for basal-ganglia circuits in fluent learned behavior.

Read the preprint “Stuttering-like” describes prolonged syllable repetition before transition; it does not imply direct equivalence with human developmental stuttering. Preprint; not yet peer reviewed.

About the lab

Understanding how brains learn and produce complex behavior.

The Gardner Lab studies birdsong vocal production to understand how biological neural networks learn and produce complex behavior. Our work ranges from machine-learning analysis of behavior and electrophysiology to cellular-scale imaging in singing birds.

Alongside this basic science, we develop new neural interfaces designed to form stable, long-term connections with the brain and peripheral nervous system.

A growing focus is designing AI around the natural temporal structure of animal communication, rather than importing assumptions from human speech.

Taylor Nakayama

Taylor studies how inhibitory-circuit gene programs regulate critical-period plasticity. Her recent work identified Calbindin (Calb1) levels in visual-cortex inhibitory neurons as a determinant of plasticity, showing that reactivating critical-period-stage gene expression can restore juvenile-like plasticity in adult circuits. In the Gardner Lab, she will investigate mechanisms of plasticity regulation through chronic neural recordings in mice.
