Memory (Week 10)

While speaking last week about the frontal lobes and their involvement in memory task, this weeks lecture covert Memory in general. Memory is a very individual process that gives us the ability to retrieve, process and store information from our past and plan for the future. Different parts of memory are responsible in the way we make decisions, judgement and know things we can recall from the past. The primary memory, today know as short-term memory and the secondary memory, known as long-term memory, are found by James (1890). Our primary memory is only able to store temporally learned information, things we randomly pick up, whereas the secondary memory can be seen as a storage for varies things, it is assessed with our conscious, while the short-term memory is picked up due to our unconscious. 

Research done by Teng and Squire (1999) examined an amnesic patient who lost the ability to memorize  due to bilateral damage on his hippocampus but was able to remember back his lost places after looking at the spatial layout of places he used to go to. That proves that hippocampus that the medial temporal lobe are necessary for declarative memory which is long-term memory. Another very important aspect of the long-term memory, and a field where much research has been done, is the difference between the non-declarative part of memory, this procedural memory is meant by skills you have learned a long time ago and can recall them whenever you like, such as swimming or riding a bike. Memory one of the major systems in the human body that makes us unique in many ways and differs us from others. 


The Human memory is like a mind map that can be accessed at any point in time, we also use that type of structure to identify problems, work out things that are important, as well as make our "mind up" about something.
