Questions & Answers

Q: What is proprioception and how does it work?

Proprioception, also known as kinesthetic sense, allows us to perceive the position and movement of our body parts in relation to each other. It enables us to know where our fingers, arms, head, and legs are without having to look or touch them.

Q: How do optical illusions deceive our senses?

Optical illusions trick our brains into perceiving something that is not actually there. They exploit the way our brains process visual information, causing us to see things differently from reality.

Q: Where are memories stored in the brain?

Memories are not stored in a single location in the brain. Instead, they are made up of complex relationships between different brain cells, forming a network of connections.

Q: Can we prove the existence of an objective reality?

No, it is impossible to prove the existence of an objective reality beyond our own perception. Our knowledge of the world is filtered through our senses and bodies, making it subjective.

Summary & Key Takeaways
