The best thing you can do for good memory , no matter who you are is:
Studies on _ patients help scientists identify different memory systems and the brain structures that support them
One factor that leads to amnesia after severe long -term alcohol abuse is
A lack of vitamin B1 in the diet .

The structure(s) destroyed in Korsakoff's syndrome is (are) the :
Deliberate recall of information that one recognizes as a memory is termed ____.
structures formed from degenerating neuronal cell bodies are called _.

H.M. was unable to form any kind of new memories. after his surgery .
Information in working is lost more easily than that in long term memory.
For example , a memory for an event is stored in long - term memory like this :
In bits and pieces so that the visual features of the memory are stored in areas of the brain associated with vision , emotion in areas associated with emotional processing, etc .
