When it comes to memory formation and memory storage, interest has been directed towards the temporal lobe (temporal lobe ) and especially towards its inner (mesial) part.

We talk about 1) short-term memory and/or working memory and 2) long-term memory.

1) We use short-term memory constantly and constantly. It reminds us of "where we are" and not least where we were during the just past time moments, "what we are doing" and doing in the just past moments of time as well as for planning our activities in the next time moment. One could speak of a continuous updating of our consciousness in the light of what has just happened; Something that is absolutely crucial for rational and understandable behavior.

Short-term / working memories are constantly formed and then forgotten within a few seconds / a few minutes. The frontal lobes in cooperation with the parietal lobes appear to be particularly important for a well-functioning short-term memory.

Typical examples of working memories are as follows.
You look up a phone number in the telephone book, glance over it, "insert" it into the short-term memory, close the directory, key in the number, hope for an answer, wait and in the meantime the number "evaporates out of your head".
Or you are going on a trip and have to pack your bag. You go through in your memory (long-term memory) what may happen during the trip and create in your short-term memory a list of things to be packed and in what order they should be picked up and put down. The list is then kept active in short-term memory until the packing is complete.

2) Long-term memory. There are usually two main types of long-term memories.

(a) explicit or declarative memories; Here we are clearly aware that we remember and we can willingly "pick out" different factual units (semantic memory): "Gothenburg is located on the west coast. Sure, that's a stroller." and select and control different memory scenes (episodic memory): "Now that I think about it, I clearly remember how we went down to the rowboat and Lillan ......".

(b) implicit or procedural memories; Here it is not about consciously "picking up" a memory image, but about unconsciously carrying out a previously learned/trained behavior, often a complex movement program that is carried out on the basis of the just current sensory impressions and the planned continued behavior (perseptuo-motor memory). So, for example, with the help of a battery, you can implicit memories e.g. ride a bike, tie your shoelaces, handle the cutlery, shape letters, etc.
