The paper investigates cerebellar neuromodulatory networks involved in motor adaptation and reinforcement feedback using PET and fMRI data, finding distinct roles for serotonin and dopamine in adaptation speed and retention.

The paper shows that beta activity in a cerebello-cortical network predicts performance based on prior outcomes, facilitating behavioral stability during environmental changes.

This study uses tTIS to show that 80Hz striatal stimulation disrupts reinforcement learning of motor skills, while 20Hz does not, indicating a frequency-dependent effect on striatal function.

This study examines if theta-burst patterned tTIS targeting the hippocampus improves associative memory consolidation in older adults, finding it enhances recollection time 24 hours post-stimulation.

This paper uses machine learning to predict how brain stimulation affects skill acquisition, finding that its benefits depend on an individual's learning efficiency rather than age.

This study demonstrates that noninvasive theta burst stimulation of the human striatum increases striatal activity and improves motor skill learning, particularly in older adults.

This study investigates how motor skill acquisition evolves with practice, identifying memory storage and execution optimization as key factors, and shows that noninvasive brain stimulation can improve motor learning in older adults.

This study investigates how deep rTMS targeting the mesial prefrontal cortex affects resting state functional connectivity in the mesial fronto-striatal circuit.
