User:CharlesWCII/Micropsia Proposal

Group Members

The members of the Micropsia group are Chuck Cahalane, Christina Farnham, and Jim Semple.

Important Information

Micropsia is a neurological disorder that affects human visual perception, causing images to become distorted so that objects are perceived to be smaller than they actually are. We will investigate the multiple causes that can lead to the condition of micropsia, including traumatic brain injury, swelling of the cornea (often due to the Epstein-Barr virus), epilepsy and neurological dysfunction. Also, as a group, we will look to better describe the link between micropsia and migraines. We will show the relation of micropsia to other conditions and diseases, such as Alice in Wonderland Syndrome, the Epstein-Barr virus, and the opposite condition, macropsia. We will describe hemimicropsia, a form of micropsia that is localized to one hemisphere of the brain and utilize the studies of patients affected with hemimicropsia to indicate how the condition can also be caused by brain lesions. Also, if available, we will explain the current research that is being done on micropsia and what new developments and breakthroughs can be expected in the future.
