Amnesia Amnesia refers to the loss of memory. Memory loss may result from two-sided (bilateral) damage to parts ofthe brain vital for memory storage, processing, or recall (the limbic system, including the hippocampus in the medial temporal lobe). Amnesia can be a symptom of several neurodegenerative diseases; however, people whose primary symptom is memory loss (amnesiacs), typically remain lucid and retain their sense of self. They may even be aware that they suffer from a memory disorder. People who experience amnesia have been instrumental in helping brain researchers determine how the brain processes memory. Until the early 1970s, researchers viewed memory as a single entity. Memory of new experiences, motor skills, past events, and previous conditioning were grouped together in one system that relied on a specific area of the brain. If all memory were stored in the same way, it would be reasonable to deduce that damage to the specific brain area would cause complete memory loss. However, studies of amnesiacs counter that theory. Such research demonstrates that the brain has multiple systems for processing, storing, and drawing on memory. 11-46 November 5, 2009 by TMO 0 comments 11 viewson *The Muslim Observer, 11-46, Kids, Science, Volume 11 Share this post Facebook Twitter Google plus Pinterest Linkedin Mail this article Print this article Tags: Amnesia, brain, brain area, brain researchers, damage, loss, medial temporal lobe, memory, memory disorder, memory memory Next: Defining Muslim Work & Faith Based Institutions: Madrasah Islamiah of Houston Previous: Christian Scholar: Was Jesus a Muslim?
