This paper uses dynamic causal modelling to show that reduced self-inhibition in the sensorimotor cortex contributes to motor fatigability.

The paper shows that observing highly-valued actions reduces response time variability and strengthens motor cortex neural representations, independent of attentional engagement.

The paper investigates motor fatigability in healthy adults through repetitive movements, finding that performance decline is linked to reduced surround inhibition in the primary motor cortex.
