Hippocampus and short term memory

What area of the cerebral cortex is used for short term memory? What is the brain mechanism for short-term memory? What should one do to improve short term memory?

How does the hippocampus affect your memory? Working memory maintenance may be part of the long term memory maintenance process by the hippocampus. Mammals and birds enjoy long periods of dreamless slow-wave sleep (SW), followed by short periods of rapid-eye-movement dreaming sleep (REM).

Nonetheless, the hippocampus may be specialized for allocentric topographical processing which impacts on short-term memory or even perception. These are primarily handled by the cortex and the cerebellum. We know that the hippocampus is involved in transferring immediate or short-term memories into long-term memories , but its specific contribution to the representation of very well-learned. These stages need not occur successively, but are, as studies indicate, broadly divided in the neuronal mechanisms they require or even in the hippocampal areas they activate. The organ also plays an important role in spatial navigation.

Because the hippocampus plays such an important role in the formation of new memories, damage to this part of the brain can have a serious long- term impact on certain types of memory. Damage to the hippocampus has been observed upon post-mortem analysis of the brains of individuals with amnesia. Hippocampal atrophy plays no role in short - term memory binding.

The globus pallidus could be part of the brain network supporting binding. Total brain atrophy does not correlate with striatal grey matter atrophy in MCI. Striatal grey matter atrophy reflects in total brain atrophy in controls.

Information regarding an event is not instantaneously stored in long- term memory. Instea sensory details from the event are slowly assimilated into long- term storage over time through the process of consolidation. Declarative memories are encoded by the hippocampus , entorhinal cortex and perirhinal cortex (all within the medial temporal lobe of the brain), but are consolidated and stored in the temporal cortex and elsewhere. There are three areas of the brain involved in explicit memory : the hippocampus , the neo-cortex and the amygdala. A loss of short term memory indicates damage to the hippocampus.

Loss of facial memory indicates damage to the inferiotemporal cortex. Conversely, if a neurologist identifies the location of stroke in a patient he or she can predict, to some extent, what memory problems a patient or caregiver should be prepared for. Is it therefore possible to stimulate the hippocampus so that facts learned for the short - term can go (faster) into long- term memory ? The hippocampus converts short - term memory into long- term memory. If you didn’t have it, you couldn’t live in the present: you’d be stuck in the past of old memories. It has many important functions.

However, the single most important one is a memory. More precisely, it transfers the data from the short-term into long-term memory. As a result, damage to the hippocampus often in memory loss, inability to form new memories, and Alzheimer’s disease.

Acquisition and recall happen while we are awake. Consolidation happens during waking and sleep. Chunking increases the capacity of short - term memory by recoding information into more meaningful units.

When large amounts of information are given, short - term memory usually remembers the first set of unrehearsed information (primacy) or the last set of unrehearsed information (recency), but few things from the middle. Short - term memory primarily takes place in the frontal lobe of the cerebral cortet. Then the information makes a stopover in the hippocampus.
