The procedural memory in human memory brain is connected with the procedure or method of learning actions and procedures. With constant repetition, that is, with a lot of practice, one can enhance his or her brain memory. Procedural memory is produced by non-associative learning. On the other hand, declarative memory involves knowledge and information about facts. For instance, in order to remember someone's phone number or name, one does not require procedures or a set of rules. In other words, the task we perform consciously is known as declarative memory and those which we perform unconsciously are known as procedural memory.

Different parts of the memory brain are also responsible for this division of memory. For example, the temporal cortex and hippocampus are involves in the formation of declarative memory, whereas few nuclei present in the cerebellum and the spinal cord are essential for the formation of procedural memory. Thus, broadly we can say that the declarative memory is controlled by higher brain mechanism, whereas procedural memory depends on the lower brain systems and regions.

The other dichotomy is about the short term and long term memory. The short term memory of any person has limited capacity and can hold only a few bits and pieces of information at a time. It also has the tendency to get disrupted quite easily with even small distracting stimuli. However, if it is left undisturbed, small term memory last for a few seconds to sometimes several hours depending on the way of learning and the person involved.

The other type of memory brain, Long Term memory occurs when information is stored for long period of time, sometimes lasting for as long as the entire lifetime of an organization. Information reaches the long term memory with the association of stimuli which is relevant to a particular organism. This can either be due to a biological predisposition or with the help of continuous repetition. Besides this, experiences charged with strong affective component often reach the long term memory more easily in comparison to others. Long term memory does not get easily disrupted and is less labile as well.
