What is Memory: Ever Wondered How it Works

Hi, there Let's start to discuss about memory.

What is memory?

This function allows you to keep a lot of information in your head and then retrieve it for use. We can also speak of memories in the plural, because there are many. Each memory is specialized in storing different types of information.

How is memory stored?

Information "kept in memory" is not physically stored in one place of the brain that will grow as our learning grows: otherwise, something will actually be the brain that will swell until it has a big head! However, the memoir leaves a trace called "memory trace":
This takes the form of new connections made between some neurons, and by modifying them (in shape and biochemical constitution).

The memory trace corresponds slightly to a new circuit, a new pathway that will be created between some neurons. 

Imagine a virgin forestimpossible to enter. This is the state of our brain if nothing is remembered. When information is stored, for example a person's telephone number, new connections are made in our brain between this person's representation and a 

combination of numbers: it is a bit like a path that is cleared to facilitate entry The forest will be given We immediately understand that access to the forest will be easier if we have a variety of phone numbers to search for:if I have retained the face, the name of the person, and if I have maintained the example of the city where it lives (then I Know if his number starts at 0299 ​​for example), or 

another index (total number of numbers), to get to the target in the jungle: find the phone number. It is also necessary to maintain the path, that is to say to take it often, if we do not want the forest to regroup: memory must be maintained to keep up. 

How Memory work

How memory works ?

We often speak of memory in the singular. In reality, memory is of many types:
  • Procedural memory: It is the first memory that develops in humans and which allows us to learn activities or actions such as walking or cycling. It is also the memory that disappears in Alzheimer's disease.
  •  Perceptual memory: It is the memory that allows us to recognize faces and objects. It develops for the second time through our five senses.
  • Flash or short-term memory: This is the well-known memory that lasts for a few seconds and which allows us to remember a series of figures for example. However after a few minutes, we forget what we had missed and the information slowly disappeared.
  • Semantic memory: It is one that allows us to store everything related to knowledge or information, for example a history lesson in school.
  • Autobiographical or episodic memory: It is the memory that stores episodes of our lives; It fills as we age.
  • Future memory: It is a memory that allows us to remember the past, but for actions that are completed in the future (eg tomorrow's meeting).

Different types of memory

It is not easy to imagine how our brain stores all the moments, information and learning that we encounter from day to day.
Brilliant and orderly, the functioning of our memory is not based on one type of "recording". Thus we have many types of memories, each of which has a role.
How Memory work


Episodic memory

It is the most famous and even the classiest. "It is a recognizable memory in time and space," says Benoit Salingue, a psychologist specializing in neurop-sychology and assistant treasurer in French Psychiatry (OFPN), particularly French psychologists. It particularly concerns autobiographical and personal memories, for example: remembering your last vacation.

Semantic memory

What is a banana? A long, curved, yellow (or green) fruit. This knowledge concerns semantic memory, which stores the general knowledge of the world. It can also have a more personal aspect, such as remembering the name of the street on which we lived in childhood.

procedural memory

Procedural memory is a part of long-term memory that refers to how to do things, also known as motor skills. As the name suggests, procedural memory stores information on performing certain procedures, such as walking, talking, and biking.

working memory

"If you are asked to repeat 5782, you repeat 5782," say psychologists who specialize in neurop-sychology. Working memory (or short term) holds a limited amount of information for a limited time. This includes our ability to immediately return a telephone number to dial.
But what about visual memory?
These are the "similarities" that apply to different types of memory: for example, for episodes we'll have images that come to mind, and even perfumes. "This is a type of preference, but a memory is formed in very sensory modalities", the expert said.
