First study to show that delivering information at the natural tempo of our neural pulses accelerates our ability to learn. Participants who received a simple 1.5-second visual cue at their personal brainwave frequency were at least three times faster when it came to improving at a cognitive task

Priming brains for optimal rhythms could help us remain quick learners throughout life, help people with learning difficulties, and give professionals an edge in training simulations, according to neuroscientists. “Each brain has its own natural rhythm, generated by the oscillation of neurons working together,” said Prof Zoe Kourtzi, senior author of the study from Cambridge’s Department of Psychology. “We simulated these fluctuations so the brain is in tune with itself – and in the best state to flourish.”
The team took alpha waves readings. The mid-range of the brainwave spectrum, this wave frequency tends to dominate when we are awake and relaxed.

“The intervention itself is very simple, just a brief flicker on a screen, but when we hit the right frequency plus the right phase alignment, it seems to have a strong and lasting effect.” “Our hypothesis is that by matching information delivery to the optimal phase of a brainwave, we maximize information capture because this is when our neurons are at the height of excitability.”
