How Your Brain Really Works
Discover why your brain is an active prediction machine rather than a passive video recorder. Learn how perception, memory, emotions, and neuroplasticity shape your everyday reality—and how to work with your neural wiring.
Like Duolingo, but for How Your Brain Really Works. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through How Your Mind Constructs Reality and Navigating Emotions and Rewiring Habits. It starts from scratch.

Key ideas in How Your Brain Really Works
- Sensory organs provide incomplete, noisy fragments rather than a flawless camera feed
- The brain uses stored memories and prior context to construct an immediate, proactive guess of what is there
- Illusions happen because the brain relies on statistically probable assumptions (such as light coming from above)
- Sensory shortcuts are evolutionary efficiencies that keep processing fast and usually accurate in daily life
- The brain cannot process all incoming sensory data, so it filters heavily based on current goals
- When attention is locked onto a specific target, salient objects right in front of your open eyes can be completely missed
- Expectations alter neural activity in sensory processing areas, not just self-reported opinions
- Believing a treatment relieves pain can prompt the brain to release genuine endogenous pain-dampening chemicals
- Anticipating intense discomfort amplifies raw pain responses
- The brain automatically produces an unconscious predictive guess before conscious reflection
- Recognizing that your initial reaction is a hypothesis allows you to deliberately inspect the raw evidence
- The brain does not record life like a video camera; it stores disconnected bits like feelings, keywords, and prominent sights
- When recalling an event, the brain stitches those pieces back together and intuitively invents plausible filler details to bridge gaps
- High confidence in a memory does not mean every specific detail was genuinely preserved
- Recalling a memory briefly unlocks it and makes it physically vulnerable to alteration
- As the brain saves the memory again, it blends the original memory with your current mood, environment, and perspective
