Sleep, off-line processing, and vocal learning.

چکیده
The study of song learning and the neural song system has provided an important comparative model system for the study of speech and language acquisition. We describe some recent advances in the bird song system, focusing on the role of off-line processing including sleep in processing sensory information and in guiding developmental song learning. These observations motivate a new model of the organization and role of the sensory memories in vocal learning.

Common Features of Neural Activity during Singing and Sleep Periods in a Basal Ganglia Nucleus Critical for Vocal Learning in a Juvenile Songbird
Reactivations of waking experiences during sleep have been considered fundamental neural processes for memory consolidation. In songbirds, evidence suggests the importance of sleep-related neuronal activity in song system motor pathway nuclei for both juvenile vocal learning and maintenance of adult song. Like those in singing motor nuclei, neurons in the basal ganglia nucleus Area X, part of t...
متن کاملSong replay during sleep and computational rules for sensorimotor vocal learning.
Songbirds learn a correspondence between vocal-motor output and auditory feedback during development. For neurons in a motor cortex analog of adult zebra finches, we show that the timing and structure of activity elicited by the playback of song during sleep matches activity during daytime singing. The motor activity leads syllables, and the matching sensory response depends on a sequence of ty...
متن کاملDoes sleep promote motor learning? Implications for physical rehabilitation.
Sleep following motor skill practice has repeatedly been demonstrated to enhance motor skill learning off-line (continued overnight improvements in motor skill that are not associated with additional physical practice) for young people who are healthy. Mounting evidence suggests that older people who are healthy fail to demonstrate sleep-dependent off-line motor learning. However, little is kno...
متن کاملOff-line processing of memory traces during human sleep: Contribution of functional neuroimaging
Sleep is thought to participate in the consolidation of recent memory traces. We tested this hypothesis in humans by using functional neuroimaging (functional magnetic resonance imaging and positron emission tomography). First, following the training procedural visuo-motor learning task (pursuit task), total sleep deprivation on the first post-training night significantly deteriorates the gain ...
متن کاملTitle: Phasic basal ganglia activity associated with high-gamma oscillation during sleep
15 The basal ganglia is thought to be critical for motor control and learning in 16 mammals. In specific basal ganglia regions, gamma frequency oscillations occur during 17 various behavioral states, including sleeping periods. Given the critical role of sleep in 18 regulating vocal plasticity of songbirds, we examined the presence of such oscillations 19 in the basal ganglia. In the song syste...
