Sensory Illusions

"Don't part with your illusions. When they are gone, you may still exist, but you have ceased to live."

— Mark Twain

Understanding Sensory Illusions

Sensory illusions are fascinating phenomena that reveal how our brain processes and interprets sensory information. These perceptual distortions occur when our sensory systems receive ambiguous or conflicting information, leading to experiences that differ from physical reality.

Studying sensory illusions is crucial for understanding the complex relationship between our senses and brain, providing insights into perception, cognition, and the fundamental mechanisms of human consciousness. They help researchers understand how we construct our reality and make sense of the world around us.

Below you will find a list of sensory illusions, categorized by modality. Click on the title of each category to explore the illusions within.
