PROCEDURAL DECLARATIVE MEMORY SYSTEMS

Procedural Declarative Memory Systems

Importance of Procedural Declarative Memory Systems

Memory is a process in which experience is stored for a long time. One memory can be recovered several times when the proper stimulus is presented. There is no consensus on how to classify the memory, but the two dichotomies often arise when we study neurologists. The first dichotomy between procedural and declarative memory, while the second dichotomy between short-term memory and long-term memory.

Procedural memory in humans, coupled with knowing the rules actions and procedures which may become quite automatic with repetition. When one studies examining some task, we can see that performance is improved (or fewer errors and faster responses, or a combination of both) with the number of repetitions of this task. With a lot or a little "practice" with a particular task is procedural knowledge. Non-associative learning, and most of the classical conventions to produce procedural memory.

Declarative memory includes complete information about the facts. To remember your phone number or names of the neuron, not require a set of rules or procedures, it is clear and includes associations with other events. Simply speaking, declarative memory is what we know consciously, and procedural memory that we do unconsciously. Although this dichotomy was first proposed to describe human memory, it is useful for the classification of animal memory. A rat can improve performance in climbing a small ladder (procedural), and remember, if there is no food on the top or not (declarative), if the light is set on or off.

Although this division of memory seems arbitrary in the first place, it is very useful in the field of neurology, as each type of memory is likely to have different types of neural substrates. For example, the hippocampus and temporal cortex seems to be involved in the formation of the declarative memory but not procedural memory. While some nuclei of the cerebellum and spinal cord, it seems necessary for procedural memories form, but do not interfere with declarative memory. In this regard, the anatomical organization of declarative memory is called controlled-mentioned mechanisms of the brain, and procedural memory appears to depend on the lower regions and systems.

The second recurring dichotomy in the study of memory in neuroscience, between short and long-lasting phase stage. Short phase is called short-term memory (STM) is determined by its limited capacity and lability, as usually only contains a few (less than seven) pieces of information, and can be broken easily, or with a strong or distracting stimuli, or brain manipulation. If CTM is easy, only takes a few seconds to several hours, depending on the type of training and body part. However, with practice, procedural data evolves, which functions mostly out-of-doors of engaged memory, and thus allows for skills to be performed more automatically. This, of course, has a very affirmative result on general presentation by setting free the mind of the need to nearly oversee and connect to the more rudimentary, mechanical skills, in alignment that vigilance can be paid to other ...
