Journal ArticleDOI
“Bird Song Metronomics”: Isochronous Organization of Zebra Finch Song Rhythm
Philipp Norton,Constance Scharff +1 more
TL;DR: A method to analyze birdsong for an underlying rhythmic regularity suggests that gesture duration constitutes the basic element of the temporal hierarchy of zebra finch song rhythm, an interesting parallel to the hierarchically structured components of regular rhythms in human music.
Journal ArticleDOI
Waltzing Taeniopygia: integration of courtship song and dance in the domesticated Australian zebra finch
TL;DR: The results suggest that male zebra finches integrate their song and dance during courtship and underscore that the choreography of movement gestures with learned vocalizations, such as hand gestures accompanying speech, is a further parallel between human and avian signalling.
Journal ArticleDOI
Young and intense: FoxP2 immunoreactivity in Area X varies with age, song stereotypy, and singing in male zebra finches
Christopher K. Thompson,Fabian Schwabe,Alexander Schoof,Ezequiel Mendoza,Jutta Gampe,Christelle Rochefort,Constance Scharff +6 more
TL;DR: FoxP2 levels may orchestrate song learning and song stereotypy in adults by a common mechanism, and data indicate that young Area X medium spiny neurons express FoxP2 at high levels and decrease expression as they become integrated into existing neural circuits.
Journal ArticleDOI
Fundamental constraints in synchronous muscle limit superfast motor control in vertebrates
Andrew F. Mead,Nerea Osinalde,Niels Ørtenblad,Joachim Nielsen,Jonathan R. Brewer,Michiel Vellema,Iris Adam,Constance Scharff,Yafeng Song,Ulrik Frandsen,Blagoy Blagoev,Irina Kratchmarova,Coen P. H. Elemans +12 more
TL;DR: It is demonstrated that to achieve rapid actomyosin crossbridge kinetics bat and songbird SFM express myosin heavy chain genes that are evolutionarily and ontologically distinct, and that all known SFMs share multiple functional adaptations that minimize excitation-contraction coupling transduction times.
Journal ArticleDOI
FoxP2 in songbirds
TL;DR: Current evidence from molecular and electrophysiological studies indicates that FoxP2 is important for shaping synaptic plasticity of specific neuron populations and thereby contributes to auditory guided vocal motor behavior in the songbird model.
