Birds Reveal their Personality when Singing
BACKGROUND Individual differences in social behaviour may have consequences for mate choice and sexual signalling, because partners should develop preferences for personalities that maximize reproductive output. Here we propose that behavioural traits involved in sexual advertisement may serve as good indicators of personality, which is fundamental for sexual selection to operate on temperament...
متن کاملTemporal hierarchical control of singing in birds.
Songs of birds comprise hierarchical sets of vocal gestures. In zebra finches, songs include notes and syllables (groups of notes) delivered in fixed sequences. During singing, premotor neurons in the forebrain nucleus HVc exhibited reliable changes in activity rates whose patterns were uniquely associated with syllable identity. Neurons in the forebrain nucleus robustus archistriatalis, which ...
متن کاملBreathing behavior during singing
Together with Curt von Euler and the late Rolf Leanderson, the author has carried out a series of investigations of the breathing behavior during the last decade. This article presents the picture of phonatoy breathing in singing that has emerged from this research. Subglottal pressure is determined by muscular forces, elasticity forces, and gravitation. The phonatoy function of the breathing a...
متن کاملDopamine neurons encode performance error in singing birds.
Many behaviors are learned through trial and error by matching performance to internal goals. Yet neural mechanisms of performance evaluation remain poorly understood. We recorded basal ganglia-projecting dopamine neurons in singing zebra finches as we controlled perceived song quality with distorted auditory feedback. Dopamine activity was phasically suppressed after distorted syllables, consi...
متن کاملOrigins of basal ganglia output signals in singing juvenile birds.
Across species, complex circuits inside the basal ganglia (BG) converge on pallidal output neurons that exhibit movement-locked firing patterns. Yet the origins of these firing patterns remain poorly understood. In songbirds during vocal babbling, BG output neurons homologous to those found in the primate internal pallidal segment are uniformly activated in the tens of milliseconds prior to syl...
