Neural Replay Mechanism Latest neuroscience research shows that inserting a few seconds of random rest during focus periods causes the brain to replay previous information at 20x speed, a phenomenon known as "Neural Replay." ā"Replay of Learned Neural Firing Sequences during Rest in Human Motor Cortex" 2. Variable Ratio Reinforcement The "variable ratio reinforcement" mechanism every 3-5 minutes, like drawing cards in games, creates an addictive feeling towards focus. 3. BRAC Physiological Rhythm Model Work cycles are recommended to be kept within 90 minutes, followed by 15-20 minutes of deep recovery rest (such as meditation, closing eyes, light activity), keeping you efficient throughout the day without exhaustion. ā"Why I Can Study 10 Hours Daily" by Bilibili UP Master Zeen This is the core logic of "Interval Flow" - scientifically distributing attention rhythm, sustainable without consumption.
