The Crazy World of Visual Hallucinations

THE CRAZY WORLD OF VISUAL HALLUCINATIONS In simplest terms, a hallucination is the perception of something that is not actually there. Medical literature defines a hallucination as a perception without a corresponding stimulus. Hallucinations can take the form of sounds or voices, smells, tastes, visions, or even physical sensations. Visual hallucinations can be as simple as sensing movement in your peripheral vision or as complex as seeing a piece of furniture move or a group of people dancing. NOW YOU SEE IT, NOW YOU DON'T Hallucinations should not be confused with optical illusions or other optical effects, even when your brain tries to make sense of confusing or inconsistent input that certain hallucinations cause. Two famous examples of phenomenon that mimic hallucinations are The Purkinje Lights and the Ganzfeld Procedure. THE PURKINJE LIGHTS • The Purkinje Lights involves an increasing sensitivity of the retina to light of shorter wave-lengths: violet, blue, and green. • As the brightness decreases, a corresponding decreasing sensitivity to light of longer wave-lengths - yellow, orange, and red - occurs. THE GANZFELD PROCEDURE The Ganzfeld Procedure involves exposing the participant to “unstructured" sensations. Half ping-pong balls are placed over your eyes so you can only see diffused white light. White noise is played through headphones. Results may vary, but many report auditory, physical, and visual hallucinations within 15 minutes to one hour. Sensory deprivation begins to Occur and your brain begins to generate images and sounds that don't really exist. These hallucinations can range from scary (hands reaching out for you and disturbing faces) to innocent and happy (unicorns and pink elephants). • Some are brief and sporadic, others are in-depth and detailed. WHY DOES YOUR BRAIN SEE WHAT ISN'T THERE? • Hallucinations do • The brain reacts not necessarily to a disturbance by creating a visual hallucination. indicate a mental condition. However, visual hallucinations do begin in the brain. Neurologists have identified 3 different categories of brain disturbances that can cause hallucinations: Irritation of the primary visual cortex (simple hallucinations). Irritation (such as a seizure) of the cortical Irritation of the visual association centers in cortices charge of visual processing. (complex hallucinations).
