You probably didn't know about the following amazing things going on in your brain. Here they are, as a short list:

  1. Your short-term memory has a max capacity of seven.
  2. Chartreuse is the most visible color.
  3. Your subconscious is smarter than you are.
  4. You have two nervous systems.
  5. Your brain is awful at probability.
  6. Your memory isn’t great either.
  7. You can perceive depth with one eye.
  8. Long-term memory shuts down during sleep.
  9. You have an instant playback feature.
