Singing, but not seizure, induces synaptotagmin IV in zebra finch song circuit nuclei.
Synaptotagmins are a family of proteins that function in membrane fusion events, including synaptic vesicle exocytosis. Within this family, synaptotagmin IV (Syt IV) is unique in being a depolarization-induced immediate early gene (IEG). Experimental perturbation of Syt IV modulates neurotransmitter release in mice, flies, and PC12 cells, and modulates learning in mice. Despite these features, ...
متن کاملDevelopmental song learning in the zebra finch
Developmental learning (for example, speech acquisition in human infants) takes place early in life but its effects may last the entire lifetime of the individual. Developmental learning is difficult to study because the behavioral changes involved span many time scales: The challenge is to relate the developmental parameters to behavioral changes, which can occur within hours as well as across...
متن کامل“Bird Song Metronomics”: Isochronous Organization of Zebra Finch Song Rhythm
The human capacity for speech and vocal music depends on vocal imitation. Songbirds, in contrast to non-human primates, share this vocal production learning with humans. The process through which birds and humans learn many of their vocalizations as well as the underlying neural system exhibit a number of striking parallels and have been widely researched. In contrast, rhythm, a key feature of ...
متن کاملVariation in the volume of zebra finch song control nuclei is heritable: developmental and evolutionary implications.
In many songbird species, females prefer males that sing a larger repertoire of syllables. Males with more elaborate songs have a larger high vocal centre (HVC) nucleus, the highest structure in the song production pathway. HVC size is thus a potential target of sexual selection. Here we provide evidence that the size of the HVC and other song production nuclei are heritable across individual m...
متن کاملDelayed development of song control nuclei in the zebra finch is related to behavioral development.
The postnatal development of two visual areas (nucleus rotundus and ectostriatum) and two song control areas (hyperstriatum ventrale pars caudale, HVc, and nucleus robustus archistriatalis, RA) of the zebra finch brain was followed from birth to adulthood. The following parameters were investigated: (1) neuron size, (2) volume of the brain nuclei, and (3) myelination of axons. The nucleus rotun...
