Unsolved mystries of brain

The brain is vital to our existence. It controls our voluntary movements, and it regulates involuntary activities such as breathing and heartbeat. The brain serves as the seat of human consciousness: it stores our memories, enables us to feel emotions, and gives us our personalities. In short, the brain dictates the behaviors that allow us to survive and makes us who we are. Scientists have worked for many years to unravel the complex workings of the brain. Their research efforts have greatly improved our understanding of brain function but still we have questions that have not been solved yet-:



  • How is information coded in neural activity?
  • How are memories stored and retrieved?
  • What does the baseline activity in the brain represent?
  • How do brains simulate the future?
  • What are emotions?
  • What is intelligence?
  • How is time represented in the brain?
  • Why do brains sleep and dream?
  • How do the specialized systems of the brain integrate with one another?
  • What is consciousness?
