Remembering stuff - II

(Previous post)

So far, the ability to store and retrieve information for future requirement evolves from genes to memory, the later being much more complicated than former.

Memory finds its most evolved, and needless to say profound, expression in humans. It is not exactly clear how memory works, but the overall flow is clear. Storing, retaining and retrieving information. One assumes that there are specialized interfaces, regions and organs to execute the specific sub-tasks which constitute memory.

There are two important aspects to memory one is learning, other is forgetting.
We learn as well as forget all the time. While learning helps in acquisition of information, forgetting helps in getting rid of irrelevant information. Without this, faculty of memory will be impaired by information overload.

Now there are some special situations where memory may not function as desired.
First, it is possible that due to shocks (for example physical accident), some of the memory, or access to it, may be lost, in worse case it is also possible that even the capability to remember things is lost. While I am not sure, this must involve some drastic disruptions in the region(s) of brain which store, retain and retrieve information.

Then there is active suppression of memory, this is not forgetting, because the memory can be accessed but there is a block against it, as a result of trauma (physical or psychological).
Now it is my assumption that this block (or state of being in denial), has two forms.
One in which the signs of trauma (responsible for denial) are explicitly visible, this may be in immediate aftermath of a shock. The other form, is when the signs are not explicit, but nevertheless trauma has adversely affected the stability and robustness of psyche.

I guess the first may be at more conscious level and the second at subconscious.

But what is the point ..... ?
