Neurological Memory :: essays research papers

The Human MemoryThe reason people exist is because of two important things memory and language, which call for been vital in the evolution of humanity. (Our ancestors needed language to explain how to light a fire to keep them warm and a memory to remember how to do it). So we have a memory because if we did non we would never have evolved far enough for you to ask this question in this place. So how does it work? The operation involve in the human memory are very complex I exit present you the neuralgic and biologic part then Aurelie will talk about the characteristics of our human memory and then Sebastien will explain the troubles of the memoryDespite big advances in recent years, memory is still a bit of mystery and there are disagreements among the experts about exactly what is going on. But now memory is seen as a function of the brain, and is not determined any more in the heart Its defined as the ability to store and retrieve information.Codes of memoryThe new ways of communication taught us that information could be on different supportsEmail, lettre, disc... The memory acts in the same way and info are supported by specific codes sensorial codes, ride codes and symbolic codes. A special memory exists to each different info tactual, visual, auditory and olfactory but these codes dont have the same importance. optic and auditory codes are the most important codes because they are the primary means of language in the memory. The auditory code is concerned with longer times than the visual one. (You remember longer a sequence of letters if you hear them than if you see them).Olfactory codes are very difficult to study and motor codes are not studied at all. These codes seem to be transitory and the info driven is encoded in the visual way or a linguistic wayThats why you probably heard about the visual memory and the auditory memory.In the long term memory the info learned becomes more and more abstract with time. The language arrived to a conce ptual memory, the visual memory arrived to an analogic memory visual- spatial but in fact an info is encoded with the two means oral and visual (a picture is named). These two codes are very complementary visual codes are good for global spatial info but bad for a sequential order and verbal codes are good for the order of encode and analyze.
