An avian basal ganglia - forebrain circuit contributes differentially to syllable 1 versus sequence variability of adult
27 28 Behavioral variability is important for motor skill learning but continues to be 29 present and actively regulated even in well-learned adult behaviors. In adult songbirds, 30 two types of song variability can persist and are modulated by social context: variability 31 in syllable structure and variability in syllable sequencing. The degree to which the 32 control of both types of adult v...
متن کاملA basal ganglia-forebrain circuit in the songbird biases motor output to avoid vocal errors.
In songbirds, as in mammals, basal ganglia-forebrain circuits are necessary for the learning and production of complex motor behaviors; however, the precise role of these circuits remains unknown. It has recently been shown that a basal ganglia-forebrain circuit in the songbird, which projects directly to vocal-motor circuitry, has a premotor function driving exploration necessary for vocal lea...
متن کاملVariability in action: Contributions of a songbird cortical-basal ganglia circuit to vocal motor learning and control.
Many motor behaviors, from walking to speaking, are acquired through experience, in particular, through trial-and-error learning. The acquisition and maintenance of such motor behaviors in a wide range of species, including humans, appear to depend on cortical-basal ganglia circuits. In this review, we discuss recent studies in songbirds that have been pivotal in informing our current understan...
متن کاملVocal Experimentation in the Juvenile Songbird Requires a Basal Ganglia Circuit
Songbirds learn their songs by trial-and-error experimentation, producing highly variable vocal output as juveniles. By comparing their own sounds to the song of a tutor, young songbirds gradually converge to a stable song that can be a remarkably good copy of the tutor song. Here we show that vocal variability in the learning songbird is induced by a basal-ganglia-related circuit, the output o...
متن کاملLong-term potentiation in an avian basal ganglia nucleus essential for vocal learning.
Vocal learning in songbirds provides an excellent model for sensorimotor learning in vertebrates, with an accessible, well-defined behavior and discrete neural substrate. The rich behavioral plasticity exhibited by songbirds, however, contrasts starkly with the scarcity of candidate cellular mechanisms. Here, we report for the first time on an activity-dependent form of synaptic plasticity in a...
