This study investigates whether human primary motor cortex represents sequences of finger movements and finds no evidence for true sequence representation, instead showing patterns explainable by individual movement components.

This study shows that motor signals improve gaze tracking accuracy in both horizontal and depth directions, even with simulated visual impairments.

The paper shows that primary motor cortex (M1) in rats transitions from responding to sleep-related forelimb twitches to wake-related movements by P12, linked to changes in sensory gating and neural connectivity.

The paper proposes and validates an alternative hypothesis for anticipatory control through sensory predictions rather than motor error-based inverse models in a simulated task.

This paper proposes a computational framework using Bayesian decision theory and state-space models to explain prism adaptation behaviour, offering mechanistic insights beyond traditional cognitive frameworks.

The paper shows that task complexity affects the magnitude, not latency, of a circuit transforming visual input into motor actions, with a fixed 100 ms latency.

The paper investigates whether visual information guides bimanual coordination through abstract spatial or body-related constraints, finding that vision contributes exclusively to spatial coding.

This study investigates how the brain represents sensory feedback delays by exposing participants to a delayed pong game and finding that delay is represented as a spatial gain change rather than a time lag.

This study investigates how reward-based learning and motor adaptation interact during skill acquisition with changing system dynamics, finding that gradual changes support learning despite short-term performance drops.

This study investigates how motor variability affects learning in a redundant task, finding that higher variability during practice leads to larger errors, regardless of whether the variability is in the task or null space.
