Aging, also known as senescence, is a physiological process that causes a slow deterioration of the functions of the body. It is characterized general degradation capacity of the body: Psychomotor, immune or reproductive. He 'spares no area of the human body, whether skin, bones, muscles but also the brain. This is called brain aging. This begins with the sl age of 20 years, but only occurs much later, around 60 to 65 year old.

Memory plays a primary role in the life of every human being. It is at the origin of knowledge, of intelligence, of the identity of each and intervenes in the essence of our business.

There are three main types of memory: Short-term memory, long term memory and sensory memory. The first in between it's is the one that allows us to remember things for a few tens of seconds, while the long-term memory allows us to remember it for hours, days, months or even years. However, all the memories do not pass the short-term memory to long term memory. This passage does is only possible if the hippocampus, a particular area of the brain is active. It makes possible the most durable registration of certain memories. Finally, the sensory memory is extremely brief and appeals to the senses, especially sight and hearing.
