Training waking rhythms, measuring sleep
Randomized controlled study · 27 healthy adults
What the study found
Twenty-seven healthy adults participated in a randomized comparison of sensorimotor-rhythm training and randomized-frequency feedback. After ten sessions, the SMR group increased the targeted 12–15 Hz activity. During a laboratory nap, researchers measured more sleep spindles and a shorter time to fall asleep.
Why it matters
This experiment shows how training a waking EEG rhythm can carry over into measurable sleep physiology.
