The memory is a restoration of the past from the material preserved in memory, in it one remembers objects, characters or lived experiences. Sometimes the memory comes from an impression or image (s) that remains in the memory of some situation, be it tragic, sad or happy. Example: "That old house reminds me of my childhood with my parents . "
A memory is a configuration of stored connections between neurons in the brain. There are approximately 100 billion such neurons, each of which can form perhaps 5,000 to 10,000 synaptic connections with other neurons, resulting in a total of about 500 to 1,000 trillion synapses in the average adult brain.
Neuroscientists usually classify memories into two types: declarative and non-declarative. Declarative memories are topics that we know we remember, like the smell of a meal or what happened yesterday afternoon. While the non-declarative ones are matters we know without consciously thinking about them, how to ride a bike.
The synapses in the brain are strengthened or weakened, when the latter happens over time, a memory loss is occurring, this alteration is known as amnesia. Also, there are other memory abnormalities such as hypomnesia (decreased memory capacity), and hypermnesia (increased or hyperactive memory).
On the other hand, the memory is an object that one person gives to another or that he brings from somewhere so that whoever receives it always remembers him, said place or object.
