Mapping Our Memories

When you observe this webpage, billions of neuron glowing as long the sinaps, trigger memories, and reveals again about what you know, and respond to new words. What will you remember depend on the brain parts work together. This is what happening on our brain when they response to something that happening on our body organ.

The memories process divided into two kinds, long-term memory and short-term memory. But in principle the long-term or short-term memories can be expressed again. The process of remembering for long-term is concluded in three ways:
  1. Immediate: Inputs received from the sense organ on the inside cortex.
  2. Then stored in just millionth second
  3. Memories work: Frontal cortex receive that information, and make available for sudden use (if ask about what are you reading, you will say “Memories”) and coordinate of use with other cortex parts.
  4. Encoding: the activity on the hippocampus and the surround area change the short-term memory into the long-term memory. The neutron connection formed when cortex stimulate by information, is strengthened and linked to the emotional condition during the process in progress. You will remember this “Hippocampus” is the Greek language which means of “sea-horse.” This brain part is named like this because have curve shaped.

The retention on the facts and events
After few second the relevant facts begin encoding with help by hippocampus and other area of lobus temporal medial.

The retention of skills and habits
The habits and motoric skill such as driving bicycle is unconscious memories. This memory depend on ganglia basal and cerebellum (small brain).

Emotional Memories
Amygdala is the central of neuron connections that is created by emotional events, especially afraid of feeling. These memories possible to act quickly if the situation is threatening.

Store and retrieve
Hippocampus is located the memories but don’t keep them. After encoding the memory locate in the cortex area as the first place of information is and processed. When needed or stimulate by the emotion, the memory will activated to be used.

Forget Process
Most of us don’t remember of the memories before 3 or 4 years old, a phenomenon which is called by child amnesia, along with increasing the age, our memories to decline gradually, especially the ability to recall things previously viewed or learned

Those all process are called as Mapping of Memory.
