Convergent transcriptional specializations in the brains of humans and song-learning birds.
Abstract
Song-learning birds and humans share independently evolved similarities in brain pathways
for vocal learning that are essential for song and speech and are not found in most
other species. Comparisons of brain transcriptomes of song-learning birds and humans
relative to vocal nonlearners identified convergent gene expression specializations
in specific song and speech brain regions of avian vocal learners and humans. The
strongest shared profiles relate bird motor and striatal song-learning nuclei, respectively,
with human laryngeal motor cortex and parts of the striatum that control speech production
and learning. Most of the associated genes function in motor control and brain connectivity.
Thus, convergent behavior and neural connectivity for a complex trait are associated
with convergent specialized expression of multiple genes.

Dr. Jarvis' laboratory studies the neurobiology of vocal communication. Emphasis is
placed on the molecular pathways involved in the perception and production of learned
vocalizations. They use an integrative approach that combines behavioral, anatomical,
electrophysiological and molecular biological techniques. The main animal model used
is songbirds, one of the few vertebrate groups that evolved the ability to learn vocalizations.
The generality of the discoveries is tested in other vocal
