Contributions of an avian basal ganglia–forebrain circuit to real-time modulation of song
Cortical–basal ganglia circuits have a critical role in motor control and motor learning. In songbirds, the anterior forebrain pathway (AFP) is a basal ganglia–forebrain circuit required for song… Expand
Lesions of an avian basal ganglia circuit prevent context-dependent changes to song variability.
Trial-by-trial variability is important in feedback-based motor learning. Variation in motor output enables evaluation mechanisms to differentially reinforce patterns of motor activity that produce… Expand
Interruption of a basal ganglia–forebrain circuit prevents plasticity of learned vocalizations
Birdsong, like speech, is a learned vocal behaviour that relies greatly on hearing; in both songbirds and humans the removal of auditory feedback by deafening leads to a gradual deterioration of… Expand
What songbirds teach us about learning
Bird fanciers have known for centuries that songbirds learn their songs. This learning has striking parallels to speech acquisition: like humans, birds must hear the sounds of adults during a… Expand
Performance variability enables adaptive plasticity of ‘crystallized’ adult birdsong
Significant trial-by-trial variation persists even in the most practiced skills. One prevalent view is that such variation is simply ‘noise’ that the nervous system is unable to control or that… Expand
Auditory feedback in learning and maintenance of vocal behaviour
Songbirds are one of the best-studied examples of vocal learners. Learning of both human speech and birdsong depends on hearing. Once learned, adult song in many species remains unchanging,… Expand

In songbirds, the basal ganglia outflow nucleus LMAN is a cortical analog that is required for several forms of song plasticity and learning. Moreover, in adults, inactivating LMAN can reverse the… Expand
Translating birdsong: songbirds as a model for basic and applied medical research.
Songbirds, long of interest to basic neuroscience, have great potential as a model system for translational neuroscience. Songbirds learn their complex vocal behavior in a manner that exemplifies… Expand
Postlearning Consolidation of Birdsong: Stabilizing Effects of Age and Anterior Forebrain Lesions
Birdsong is a learned, sequenced motor skill. For the zebra finch, learned song normally remains unchanging beyond early adulthood. However, stable adult song will gradually deteriorate after… Expand

Cues for sound localization are inherently spatially ambiguous. Nevertheless, most neurons in the barn owl's optic tectum (superior colliculus) have receptive fields for broadband noise stimuli that… Expand
