Human brain

How does the human brain store and retrieve memories?


"Memory is Short-Term or Long-Term

New sensory information is processed first into a form of memory called intermediate-term memory for a period of several seconds and then transferred into short-term memory for a period of seconds to minutes. The new information, depending upon its perceived importance, may be processed by a process called consolidation into long-term memory where it is stored for periods of days to years.

Storage is the more or less passive process of retaining information in the brain, whether in the sensory memory, the short-term memory or the more permanent long-term memory. Each of these different stages of human memory function as a sort of filter that helps to protect us from the flood of information that confront us on a daily basis, avoiding an overload of information and helping to keep us sane. The more the information is repeated or used, the more likely it is to be retained in long-term memory (which is why, for example, studying helps people to perform better on tests). This process of consolidation, the stabilizing of a memory trace after its initial acquisition, is treated in more detail in a separate section.

Since the early neurological work of Karl Lashley and Wilder Penfield in the 1950s and 1960s, it has become clear that long-term memories are not stored in just one part of the brain, but are widely distributed throughout the cortex. After consolidation, long-term memories are stored throughout the brain as groups of neurons that are primed to fire together in the same pattern that created the original experience, and each component of a memory is stored in the brain area that initiated it (e.g. groups of neurons in the visual cortex store a sight, neurons in the amygdala store the associated emotion, etc). Indeed, it seems that they may even be encoded redundantly, several times, in various parts of the cortex, so that, if one engram (or memory trace) is wiped out, there are duplicates, or alternative pathways, elsewhere, through which the memory may still be retrieved."

Your brain has a lot of information data and memories to remember. And the human brain does that by different processes through out your brain for example there is the intermediate-term memory it hold the memories or any information or data in the brain for years, days or hours.

MEMORY RECALL/RETRIEVAL Commentary: I think the human brain is very festinating I have all ways been interested in the human brain. I think that it is very festinating that the human brain can store memories in it for a matter of years and days. And that there is stages that will help your brain not over flow with tunes of information.

Memory is Short-Term or Long-Term

The brain stores memories in two ways. Short-term memories like a possible chess move, or a hotel room number are processed in the front of the brain in a highly developed area called the pre-frontal lobe, according to McGill University and the Canadian Institute of Neurosciences, Mental Health and Addiction.

Short-term recollection is translated into long-term memory in the hippocampus, an area in the deeper brain. According to McGills , the hippocampus takes simultaneous memories from different sensory regions of the brain and connects them into a single "episode" of memory, for example, you may have one memory of a dinner party rather than multiple separate memories of how the party looked, sounded , and smelled.

In a brain scan, scientists see these different regions of the brain light up when someone is recalling an episode of memory, demonstrating how memories represent an index of these different recorded sensations and thoughts.

The hippocampus helps to solidify the pattern of connections that form a memory, but the memory itself depends on the solidity of the connections between individual brain cells, according to research from McGill and from New York University.

The human brain can store any thing what u see what you smell anything u could imagine. McGrill research the topic (" How does the brain store and retrieve memories?"). And it proven that its true that in article is real.("Memory Storage - Memory Processes - The Human Memory." ).


Memory is Short-Term or Long-Term Commentary: The long term memory is very festinating to me. I think its so cool how the brain can hold memories for along time. And how it goes in the process of doing it.
