Significant experimental, computational, and theoretical work has identified rich structure
within the coordinated activity of interconnected neural populations. An emerging challenge …

The brain plans and executes volitional movements. The underlying patterns of neural
population activity have been explored in the context of movements of the eyes, limbs …

The brain's remarkable ability to learn and execute various motor behaviours harnesses the
capacity of neural populations to generate a variety of activity patterns. Here we explore …

Motor behaviors are often planned long before execution but only released after specific
sensory events. Planning and execution are each associated with distinct patterns of motor …

Current theories suggest that an error-driven learning process updates trial-by-trial to
facilitate motor adaptation. How this process interacts with motor cortical preparatory activity …

Incentives tend to drive improvements in performance. But when incentives get too high, we
can" choke under pressure" and underperform right when it matters most. What neural …

How do patterns of neural activity in the motor cortex contribute to the planning of a
movement? A recent theory developed for single movements proposes that the motor cortex …

The signaling capacity of a neural population depends on the scale and orientation of its
covariance across trials. Estimating this" noise" covariance is challenging and is thought to …

Faster movements are typically more variable—a speed-accuracy trade-off known as Fitts'
law. Are movements that are initiated faster also more variable? Neurophysiological work …

A long-standing challenge in motor neuroscience is to understand the relationship between
movement speed and accuracy, known as the speed-accuracy tradeoff. Here, we introduce …
