From electromyographic activity to frequency modulation in zebra finch song
(Springer, 2017-11)
Behavior emerges from the interaction between the nervous system and peripheral devices. In the case of birdsong production, a delicate and fast control of several muscles is required to control the configuration of the ...
Acoustic signatures of sound source-tract coupling
(American Physical Society, 2011-04)
Birdsong is a complex behavior, which results from the interaction between a nervous system and a biomechanical peripheral device. While much has been learned about how complex sounds are generated in the vocal organ, ...
Special Article: From Birdsong to Babel: the canine connection in the origin of human language
(Universidad Estatal a Distancia, Costa Rica, 2013)
Physiologically driven avian vocal synthesizer
(American Physical Society, 2010-03)
In this work, we build an electronic syrinx, i.e., a programmable electronic device capable of integrating biomechanical model equations for the avian vocal organ in order to synthesize song. This vocal prosthesis is ...
Interaction between telencephalic signals and respiratory dynamics in songbirds
(American Physiological Society, 2012-03)
The mechanisms by which telencephalic areas affect motor activities are largely unknown. They could either take over motor control from downstream motor circuits or interact with the intrinsic dynamics of these circuits. ...
Elemental gesture dynamics are encoded by song premotor cortical neurons
(Nature Publishing Group, 2013-02-27)
Quantitative biomechanical models can identify control parameters that are used during movements, and movement parameters that are encoded by premotor neurons. We fit a mathematical dynamical systems model including ...
Dynamics behind rough sounds in the song of the Pitangus sulphuratus
(American Physical Society, 2020-12)
The complex vocalizations found in different bird species emerge from the interplay between morphological specializations and neuromuscular control mechanisms. In this work we study the dynamical mechanisms used by a ...
Subharmonics in the solutions of a model of the song motor nuclei in songbirds
(Elsevier Science, 2005-10)
Songbirds produce their vocalizations by means of a vocal organ called syrinx. A relatively small number of parameters are cyclically changed in order to produce a song. These time-dependent parameters are generated by a ...
A dynamical system as the source of augmentation in a deep learning problem
(Elsevier, 2019-06)
In this work we build a convolutional neural network capable of identifying individual birds by their songs. Since the actual data available from each individual is very limited, we use a dynamical system capable of ...
