  • Mapping Out the Brain

    Scientists at the University of California San Diego are making the first microscopic survey of an entire human brain.  But not just any brain, the brain of Henry Molasion who passed away on Dec. 2nd (my birthday) 2008.  Psychologists and psychology students may be more familiar with Molasion's pseudonym, HM, which he used during the 50 some years as a research subject.  When HM was 26 years old he underwent a surgery to treat a severe case of epilepsy.  While the surgery was successful in its primary goal, the procedure left HM with a case of anterograde amnesia.  Fans of the movie "Momento" --whose main character was partially based on HM---may be familiar with anterograde amnesia which is define as the inability to form new memories.  Because of the severity of HM's condition he has been the subject of numerous studies and has showed us a great deal about how memory works.  And it seems --even in death---HM will continue to give us insight.  By freezing HM's brain and carefully taking approximately 2,500 slices, about 70 microns (70 micrometers) thick, researchers will be able to create a 3 dimensional replication of HM's brain with detail that goes down to the cellular level.  This is really exciting stuff, especially for those interested in neuroscience and memory formation.  Even more exciting, according to the New York Times article, the survey should be available to anyone that wants to see it.

About Me

  • I am a biology student currently living in Kalamazoo Mi. I have a number of interests including but not limited to different fields of biology, chemistry and physics, with a special interest in medicine. I love music and I'm a devout skeptic who contributes an occasional rant concerning various areas of psuedo-science, especially those related to the medical field as well as any other random thoughts made by a very Strange Brain.
