Your Brain Predicts Reality: How Perception Shapes Everything You Experience

The Longevity Podcast: Optimizing HealthSpan & MindSpan

We explore how the brain fuses sight and sound into one stable reality, predicts away saccade blur, and even moves the eardrum to align hearing with vision. We connect top-down control to simulation-based thinking, environmental acoustics, deep focus, and the social power of rhythm.
• superior colliculus as early multisensory hub
• predictive mapping across saccades for visual stability
• microsecond timing and pinna cues for sound localization
• visual dominance and the ventriloquist effect
• self-silencing during speech and eardrum shifts with eye movements
• thinking as sensory-motor simulation with limited bandwidth
• echoes, room acoustics, and the cocktail party effect
• visual narrowing as a lever for flow and attractor states
• rhythm as a driver of group unity and shared intention
