How we Remember and How to Improve Memory

 

Onyourfingertips drills help your brain to remember by repeating questions until perfect scores are attained.
The brain's associative process moves the information from short-term memory into permanent memory. Not all the information is permanently remembered in one revision, however, having the ability to quickly repeat a past drill allows for fast memorization of large quantities of information. The details of how the brain does this is presented below.

SHORT-TERM MEMORY
In the course of a day, there are many times when you need to keep some piece of information in your head for just a few seconds. Maybe it is a number that you are 'carrying over' to do a subtraction, or a persuasive argument that you are going to make as soon as the other person finishes talking. Either way, you are using your short-term memory.
In fact, those are two very good examples of why you usually hold information in your short-term memory: to accomplish something that you have planned to do. Perhaps the most extreme example of short-term memory is a chess master who can explore several possible solutions mentally before choosing the one that will lead to checkmate.
This ability to hold on to a piece of information temporarily in order to complete a task is specifically human. It causes certain regions of the brain to become very active, in particular the pre-frontal lobe.

     This region, at the very front of the brain, is highly developed in humans. It is the reason that we have such high, upright foreheads, compared with the receding foreheads of apes. Hence it is no surprise that the part of the brain that seems most active during one of the most human of activities is located precisely in this prefrontal region that is well developed only in human beings.
Human memory is a complex phenomenon, however, and involves other regions of the brain as well.

LONG-TERM MEMORY

Information is transferred from short-term memory (also known as working memory) to long-term memory through the hippocampus, so named because its shape resembles the curved tail of a seahorse (hippokampos in Greek). The hippocampus is a part of the cortex, and is located in the inner fold of the temporal lobe.

All of the pieces of information decoded in the various sensory areas of the cortex converge in the hippocampus, which then sends them back where they came from. The hippocampus is a bit like a sorting centre where these new sensations are compared with previously recorded ones. The hippocampus also creates associations among an objectís various properties.

When we remember new facts by repeating them or by employing various mnemonic devices, we are actually passing them through the hippocampus several times. The hippocampus keeps strengthening the associations among these new elements until, after a while, it no longer needs to do so. The cortex will have learned to associate these various properties itself to reconstruct what we call a memory.
