DiverScan is a deep-learning framework that uses attention mechanisms to analyze animal behavior data, identifying condition-specific features across diverse experiments.

This study identifies diverse ultrasonic vocalizations in rats beyond the traditional high-short/low-long dichotomy, highlighting the need for broader research into complex affective states.

The paper identifies a brainstem circuit that transmits both sensory and motor information from aversive experiences to the amygdala, enhancing defensive behaviors and emotional memory formation.

This study shows rats can spontaneously categorize familiar and unfamiliar conspecifics using a habituation-dishabituation task with multiple stimuli.

This study investigates how neural entrainment relates to anticipatory processing of musical meter using EEG and dual-meter sound stimuli, finding that entrainment to attended features predicts P300 responses to metrical violations.

This study investigates how auditory feedback linked to locomotion affects rats' spontaneous movement, finding increased locomotion distance when feedback matches movement velocity, but the effect is short-lived.

This study investigates the role of the rat granular retrosplenial cortex in interval timing by analyzing neural activity during trace fear conditioning.

The paper shows that consistent spectral cues improve perceptual accuracy in distinguishing subdivided rhythmic patterns, highlighting the role of spectral properties in rhythm perception.

This study shows that rats prefer joint feeding with unfamiliar non-cagemates over solitary feeding, indicating a high degree of social tolerance and prosocial behavior.

This study shows that dopaminergic neurons in Drosophila update the value of odors during navigation, independent of associative learning.

This study shows that inhibiting CA2 neurons in mice reduces the temporal and informational precision of CA1 ensemble reactivation during sharp-wave ripples.

This study investigates how arousal affects auditory responses in Bengalese finches using gene expression, finding that low-arousal states show less auditory gating and potential differences from zebra finches.

The paper compares oxytocin sequence and expression between domesticated Bengalese finches and wild munias, finding reduced OT mRNA expression in finches.

The paper introduces a viral tool for fast retrograde labeling of projection neurons in songbirds and mice, enabling detailed analysis of vocal learning circuits.

The paper shows that spontaneous motor variability in vocal pitch predicts adaptive compensation for auditory feedback shifts in humans.

The paper introduces a method to segment ultrasonic vocalizations from rodents in noisy data, showing improved performance over conventional methods.

This study shows that native-language advantages in emotional cue recognition are due to unfamiliarity with speech sounds, not cultural expression differences.
