How the human memory functions is a very intricate and misunderstood subject. As this subject affects each and every one of us in our daily living, there have been numerous detailed studies undertaken to determine how this complex activity takes place within our brains. In reality, while there has been a great amount of progress in understanding the human brain and human memory it is impossible to reach any absolute consensus among the experts as to the mechanics of human memory. In simple terms the human memory can be likened to a DVD recorder, although it is far more complicated in its workings.



The human memory is able to retain key information that we like to revisit time and time again. It is also extremely complex in that it allows us to recall feelings and sensations that we have experienced. As well as these elaborate functions our memory recalls how to carry out relatively simple daily functions such as eating, walking, talking and the like.

There is so much more for scientists to learn about the human memory and as previously alluded to, the study of the human memory will give rise to many more disagreements than agreements among the leading experts in the study of the human brain and how it functions. Nevertheless, what we do know is the human memory involves three main functions which are short term memory, sensory memory and long term memory. There is also one more type which is known as the working memory.

In sensory memory the human memory recalls something that happens in a split second and occurs after the mind forms its first perception. It is like being able to look at at an object and then immediately commit the details to memory. Sometimes some of these details or information actually moves into short term memory. This is the part of a human's memory that enables us to recall a happening or object a few seconds or even a minutes after it has first occurred.

The newly discovered human memory function that is referred to as working memory is very much like short term memory because it is a function where there is not very large storage needed to perform tasks inside the mind. The difference between working memory and short term memory is that the former is more to do with purpose while the latter is dependent on duration of time.

The other human memory function that interests many people is the long term memory, that unlike short term memory does not disappear after a few moments. Information committed to the human long term memory can possibly remain in the brain for many years. There is no definitive agreement among psychologists about the duration of long term memory, some argue that it is a memory that lasts forever, while others feel it only lasts for a few years at the most.

The study of the human brain and human memory functions continues and our understanding of its mechanics grows day by day. Even with the amazing technological advancements we see on a daily basis I doubt if we will ever truly get to know everything about the human brain and how it works - well at least not in our lifetimes.
