Accidents and Diseases Reveal Some of the Anatomy of Memory


The case of HM: Left and right hippocampus and nearby regions (including the rhinal cortex) removed surgically to control epilepsy (hippocampus is an internal part of the temporal lobe) --->
Produced severe amnesia- loss of ability to form new long term memories Short term memory is OK
Long term memory of events before the surgery also OK

Korsakoff's syndrome:
Found mostly in alcoholics with vitamin deficience (thiamine deficiency)
Damages mammilary bodies and other nearby parts of the hypothalamus and thalamus --->
This damage produces an amnesia similar to the type of HM

Other diseases -->other parts of the brain such as the cerebellum and the forebrain
