Your brain is always a fraction of a second behind the present

- The brain processes sensory information with a delay of about 100 milliseconds, making our perception slightly outdated.
- Neural transmission is slow compared to electrical signals, leading to anticipatory predictions to interact effectively with the world.
- This predictive mechanism explains phenomena like the inability to tickle oneself and wobbling on broken escalators.
- During rapid eye movements (saccades), the brain suppresses visual input and backdates experiences to maintain a smooth perception.
- Back-dating can cause illusions, such as the second hand of a clock appearing to pause when first looked at.
- Overall, the brain compensates for sensory delays through prediction and temporal adjustments, creating a seamless subjective experience.
