Understanding Optical Illusions: How the Brain Perceives Deception

Optical illusions primarily affect the visual cortex, which is located in the occipital lobe at the back of the brain. The visual cortex is responsible for processing visual information and interpreting it into meaningful perceptions. Optical illusions occur when the brain misinterprets or misprocesses the visual stimuli, leading to a sensory deception or a misleading visual perception.
