What causes hallucinations when you have schizophrenia?
In: Biology
Your brain is good at showing you things. You believe what you dream, and your brain often fills in details that you think you see, but when you pay attention, they go away. For example you might realize something you thought you saw out of the corner of your eye isn’t really there.
For example, you can imagine looking up and seeing a rat scurry across the room. It’s not happening, but you can visualize in your mind what it might look like if it were to happen.
With schizophrenia, the brain’s inhibition that prevent this from happening when awake or actively watching isn’t working. The idea of a rat scurrying can become a rat vividly scurrying.
This isn’t just what you see, but also what you hear, etc.
