How does the brain create hallucinations?
In: Biology
Your entire reality is within your head. Your eyes, your ears, your touch and taste and smell, they are only sending signals to the brain. The brain manually receives, processes, and interprets those signals, and it then creates the “reality” that you are experiencing.
Because of that, its very easy to cause the brain to distort or misinterpret those signals, or create false signals that never existed, thus creating hallucinations, its as real inside your brain as actual reality is.
An example that is somewhat related that shows how easy it is for a disconnect to happen between your senses and what your brain creates as a reality. Every waking moment of your life, you can see your nose. Your nose is in clear view of your eyes, your eyes are sending that information to your brain every waking moment of your life. But i’m betting you didn’t realize this until i said something right? Thats because your brain decided that processing the constant signals from your eyes that say “hey there is a nose here” were unnecessary, and it just doesn’t process those and effectively erases the existence of the nose from the final picture you see in your head, until i brought attention to it and because seeing the nose is now important to the brain, its not ignoring those signals and now you can see your nose.
