This study shows that vestibular stimulation improves the timing precision of movements synchronized to musical rhythms by enhancing predictive motor execution.

This study uses loud acoustic stimulation to demonstrate an online reticulospinal contribution to long-latency reflexes in humans, showing facilitation of the reflex but not the short-latency reflex.

The paper shows that neural rhythmicity aids memory retrieval when the number of candidate items exceeds four, based on reaction time and electrophysiological data.

This study examines how sleep-wake schedules affect performance, physiology, and psychology in early and late chronotypes, finding distinct patterns based on preferred sleep timing.

This study examines how β-band sensorimotor rhythm modulation differs between and within individuals during force-tracking tasks and its relationship to corticomuscular coherence.

This study investigates the relationship between flow state and frontal-midline theta activity using EEG during video gameplay, finding no correlation in most participants.

The paper shows that reaction times fluctuate in the theta frequency range when recalling sequential memory, suggesting rhythmic rather than stable accessibility to sequential working memory.

The paper investigates working memory by measuring recall times for memorized color/letter pairs, finding that recently encoded memories are retrieved faster, suggesting an active state with limited capacity.

This study compares sensorimotor rhythm modulation during kinesthetic motor imagery between gymnasts and non-gymnasts using EEG, finding greater desynchronization in gymnasts.

This study examines corticomuscular coherence during unipedal stance and finds increased cortical control of muscle activity compared to bipedal stance.
