Rehearsing information immediately after being given it may be all you need to make it a permanent memory, a University of Sussex study suggests [medicalxpress.com].
Psychologists found that the same area of the brain activated when laying down a memory is also activated when rehearsing that memory.
The findings, published on Oct. 27, 2015 in the Journal of Neuroscience, have implications for any situation in which accurate recall of an event is critical, such as witnessing an accident or crime.
The study showed that the brain region known as the posterior cingulate—an area whose damage is often seen in those with Alzheimer's—plays a crucial role in creating permanent memories.
This region not only helps us to recall the episodic details of an event but also integrates the memory into our knowledge and understanding, which makes it resistant to forgetting.
