Memory and it’s Types

Being able to remember experiences is essential to existence.

Memory enables us to learn, be creative and understand the world around us. There are three levels of memory…

1. Sensory memory which makes us aware of the surroundings.

2. Short – term Memory. Which briefly holds things that we need to deal with at the moment.

3. Long – term Memory which are three types, provide storage of skills, facts and events.

Types of memory

1. Sensory memory

Sensory memory is in control of the moments when you are aware of the surroundings whether you are riding the bike or watching the TV. It stores a fleeting impression of sides sounds, smells ,taste and other sensations before being updated. Most sensory memories are lost, to prevent the brain being overwhelmed, but any importance sensations are retained in short.

2. Memory storage

There is no single memory store in the brain.Among the key memory areas are the cerebral cortex, the outer layer of the brain cerebral hemisphere and the hippocampus ,located within those hemispheres.

The hippocampus constantly relays memory signals to areas of the cortex that deals with the vision,hearing, and other sensations until they store long – term memory that can be recalled.

3. Short term memory

Only the most significant sensations you experience are remember short term memory stores things just long enough to work on them. For example if you read a phone number it retains its so you can dial it. Most short term memories are stored for seconds then discarded, but important ones are shunted to long term memory.

4.Procedural memory

One of the three types of long term memory , Procedural memory is located deep inside the brain it stores the skills that people learn through practice from the walking, to more complex such as playing a piano. Once learned, procedural memory makes sure these skills and “how to” knowledge are rarely lost.

5. Semantic memory

You can read this words and make sense of what they mean because of semantic memory. Located in the sides of cerebrum, semantic memory is to use the words and language you have learned since infancy both inside and out of school along with facts.

6. Making memories

While most sensations last just few seconds, some, such as the sights, sounds and the smell of funfair are processing by the hippocampus and pass into long term memory in the cerebral cortex. Here, Nerve create new connections to create a “Memory- web”; from which memories can be stored and recalled over a lifetime.

7. Episodic memory

Remembering a great holiday depends on episodic memory. Located in different parts of the cerebral cortex, such as those for vision and hearing, episodic memory stores specific life events. One way to “jog” your episodic memory is to look at the photographs this can switch on parts of cortex, so they recreate the event.
