Cortical pattern generation during dexterous movement is input-driven

BA Sauerbrei, JZ Guo, JD Cohen, M Mischiati, W Guo… - Nature, 2020 - nature.com
The motor cortex controls skilled arm movement by sending temporal patterns of activity to
lower motor centres. Local cortical dynamics are thought to shape these patterns throughout …

A motor cortex circuit for motor planning and movement

N Li, TW Chen, ZV Guo, CR Gerfen, K Svoboda - Nature, 2015 - nature.com
Activity in motor cortex predicts specific movements seconds before they occur, but how this
preparatory activity relates to upcoming movements is obscure. We dissected the conversion …

Distinct descending motor cortex pathways and their roles in movement

MN Economo, S Viswanathan, B Tasic, E Bas… - Nature, 2018 - nature.com
Activity in the motor cortex predicts movements, seconds before they are initiated. This
preparatory activity has been observed across cortical layers, including in descending …

Z Gao, C Davis, AM Thomas, MN Economo, AM Abrego… - Nature, 2018 - nature.com
Persistent and ramping neural activity in the frontal cortex anticipates specific movements,,,,–
. Preparatory activity is distributed across several brain regions,, but it is unclear which brain …

Cortical preparatory activity indexes learned motor memories

X Sun, DJ O'Shea, MD Golub, EM Trautmann, S Vyas… - Nature, 2022 - nature.com
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 …

Robust neuronal dynamics in premotor cortex during motor planning

N Li, K Daie, K Svoboda, S Druckmann - Nature, 2016 - nature.com
Neural activity maintains representations that bridge past and future events, often over many
seconds. Network models can produce persistent and ramping activity, but the positive …

Neural population dynamics during reaching

MM Churchland, JP Cunningham, MT Kaufman… - Nature, 2012 - nature.com
Most theories of motor cortex have assumed that neural activity represents movement
parameters. This view derives from what is known about primary visual cortex, where neural …

Emergence of reproducible spatiotemporal activity during motor learning

AJ Peters, SX Chen, T Komiyama - Nature, 2014 - nature.com
The motor cortex is capable of reliably driving complex movements, yet exhibits
considerable plasticity during motor learning,,,,,,,. These observations suggest that the …

Opponent and bidirectional control of movement velocity in the basal ganglia

EA Yttri, JT Dudman - Nature, 2016 - nature.com
For goal-directed behaviour it is critical that we can both select the appropriate action and
learn to modify the underlying movements (for example, the pitch of a note or velocity of a …

Cortical processing of flexible and context-dependent sensorimotor sequences

D Xu, M Dong, Y Chen, AM Delgado, NC Hughes… - Nature, 2022 - nature.com
The brain generates complex sequences of movements that can be flexibly configured
based on behavioural context or real-time sensory feedback, but how this occurs is not fully …
