ARBUR is a machine learning system that clusters rat ultrasonic vocalizations and detects social behaviors, revealing communication patterns and novel findings in social interactions.

This study tests the hypothesis that perceptual salience drives auditory streaming in eastern gray treefrogs, finding no evidence that salient pulse rise time differences promote stream segregation.

This study shows that lesions in the mMAN region increase variability in song syntax of Bengalese finches, suggesting its role in sequencing vocal elements.

The paper shows that in mice, ultrasonic vocalizations (USVs) are less represented in the inferior colliculus compared to lower frequency social vocalizations, despite being more common.

The paper identifies proteins and regulatory elements associated with vocal learning by analyzing bat neural activity and epigenomic data.

This study shows that early damage to the anterior cingulate cortex in marmosets disrupts the development of social vocalizations and alters downstream brain structures.

The paper investigates neural dynamics in the rodent motor cortex during vocal production, showing temporal scaling of premotor firing patterns enables vocal flexibility.

The paper shows that daily vocal exercise is necessary for songbirds to maintain peak vocal muscle performance and that this affects song quality and mate preference.

The paper investigates the role of the anterior forebrain pathway (AFP) in parrots' vocal learning, finding that its inactivation disrupts the production of learned vocalizations with individual signatures, unlike songbirds.

The paper shows that mesostriatal dopamine pathways in songbirds are spatially segregated before vocal learning begins.

This study examines frontal cortex activity in marmoset monkeys during social vocal communication, finding distinct neural patterns for different vocalizations and theta-band oscillations linked to vocal phrase timing.
