Modeling temperature manipulations in a circular model of birdsong production
(Instituto de Física de Líquidos y Sistemas Biológicos, 2018-01)
The nature of the neural mechanisms in the birdsong motor pathway that lead to the generation of respiratory patterns are a matter of extensive debate. In a top-down control paradigm, vocal gestures emerge from a unique ...
Low-dimensional dynamical model for the diversity of pressure patterns used in canary song
(American Physical Society, 2009-04)
During song production, oscine birds produce large air sac pressure pulses. During those pulses, energy is transferred to labia located at the juncture between the bronchii and the trachea, inducing the high frequency ...
Vocal divergence between two disjunct populations of Giant Antshrike (Batara cinerea) is related to environmental conditions
(Wiley-Blackwell, 2019-05-01)
Variation in the avian vocal signals emitted may have a significant impact on species evolution. Vocal divergence in suboscine species like Giant Antshrike (Batara cinerea) may be associated with selective adaptation, since ...
Neural coding of sound envelope structure in songbirds
(Springer, 2017-12-12)
Songbirds are a well-established animal model to study the neural basis of learning, perception and production of complex vocalizations. In this system, telencephalic neurons in HVC present a state-dependent, highly selective ...
MHC-mediated sexual selection on birdsong: Generic polymorphism, particular alleles and acoustic signals
(Wiley Blackwell Publishing, Inc, 2018-06)
Several hypotheses predict that the major histocompatibility complex (MHC) drives mating preference in females. Olfactory, colour or morphological traits are often found as reliable signals of the MHC profile, but the role ...
Neurally driven synthesis of learned, complex vocalizations
(Cell Press, 2021)
Temperature manipulation of neuronal dynamics in a forebrain motor control nucleus
(Public Library of Science, 2017-08)
Different neuronal types within brain motor areas contribute to the generation of complex motor behaviors. A widely studied songbird forebrain nucleus (HVC) has been recognized as fundamental in shaping the precise timing ...
A circular model for song motor control in Serinus canaria
(Frontiers Research Foundation, 2015-03)
Song production in songbirds is controlled by a network of nuclei distributed across several brain regions, which drives respiratory and vocal motor systems to generate sound. We built a model for birdsong production, whose ...
Prosthetic Avian vocal organ controlled by a freely behaving bird based on a low dimensional model of the biomechanical periphery
(Public Library of Science, 2012-06)
Because of the parallels found with human language production and acquisition, birdsong is an ideal animal model to study general mechanisms underlying complex, learned motor behavior. The rich and diverse vocalizations ...
Spike timing and synaptic plasticity in the premotor pathway of birdsong
(Springer, 2004-12)
The neural circuits of birdsong appear to utilize specific time delays in their operation. In particular, the anterior forebrain pathway (AFP) is implicated in an approximately 40- to 50- ms time delay, ΔT, playing a role ...
