Decoding the Brain's Perception: Distinguishing Reality from Imagination

The brain has a delicate balancing act to accurately distinguish between mental imagery and reality. Researchers have found that the strength of the signal may be regulated in the frontal cortex, which analyzes emotions and memories. However, it remains unclear what determines the vividness of a mental image or the difference between the strength of the imagery signal and the reality threshold. This mechanism could have implications for conditions such as schizophrenia, where the distinction between imagination and perception breaks down. Further research is needed to understand the emergence of hallucinations and the role of sensory hyperactivity in these conditions.
