To test the impact on learning, her subjects first learned a complex sequence of finger movements – a little like learning to play a tune on the piano – before taking 30 minutes of neurofeedback. The benefits were immediate – straight after the training they were about 10% better than the controls, suggesting the computer game really had begun to stabilise their memories as if they were actually asleep. Importantly, the improvements continued to grow as they were tested throughout the following week, supporting her theory that neurofeedback could help memories to blossom as you sleep.
