Trial-to-trial variability in the execution of movements and motor skills is ubiquitous and
widely considered to be the unwanted consequence of a noisy nervous system. However …

Learning motor skills evolves from the effortful selection of single movement elements to
their combined fast and accurate production. We review recent trends in the study of skill …

The basal ganglia are known to influence action selection and modulation of movement
vigor, but whether and how they contribute to specifying the kinematics of learned motor …

Motor cortex is widely believed to underlie the acquisition and execution of motor skills, but
its contributions to these processes are not fully understood. One reason is that studies on …

Individual differences in motor learning ability are widely acknowledged, yet little is known
about the factors that underlie them. Here we explore whether movement-to-movement …

Rapid and reversible manipulations of neural activity in behaving animals are transforming
our understanding of brain function. An important assumption underlying much of this work …

Many behaviors are learned through trial and error by matching performance to internal
goals. Yet neural mechanisms of performance evaluation remain poorly understood. We …

Neural sequences are a fundamental feature of brain dynamics underlying diverse
behaviours, but the mechanisms by which they develop during learning remain unknown …

Learning to vocalize depends on the ability to adaptively modify the temporal and spectral
features of vocal elements. Neurons that convey motor-related signals to the auditory system …

Trial-to-trial movement variability can both drive motor learning and interfere with expert
performance, suggesting benefits of regulating it in context-specific ways. Here we address …
