Where Is Your Memory In Your Brain

Where Is Memory Stored In The Brain

Your Brain is You: Learning and Memory (Part 5 of 6)

Every day you observe and experience things and go on adding new information in to your master organ. Though you may at times find it difficult to absorb new things, the capacity of your brain never seems to be exhausted. But how and where is memory stored in the brain?

According to Amen the author of Memory rescue: supercharge your brain, reverse memory loss, and remember what matters most, the brains storage capacity is vast. He however adds, It is almost impossible to calculate exactly how many memories and pieces of information the human beings can hold in their brain.

S Of Brain Involved In Memory Processes

Technically our brain has many different compartments and they work differently to do certain functions. Not all of the brain is involved in memory. Hippocampus is the main region of the brain involved in memory processes.

When it comes to storing or making a memory Hippocampus is involved. It is the primary regulator of the process of memory retention. It is a seahorse-shaped part of the temporal lobe. It acts as a bridge in engaging all the parts of the brain required to keep a memory. Although it is not involved in retrieving, formation and consolidation are highly dependent on Hippocampus. Consolidation is the fixing or storing a memory permanently.

Suppose due to a dire turn of event someone you know had most of the part of his Hippocampus removed. This person will not be able to remember anything new. Thus, memories will not be retained. However, the ability to recall older memories that happened before removing the Hippocampus will remain unaffected.

Reasons Behind Forgetting Things

The brain can store a large sum of data in it, but some things are lost. Forgetting is as essential as retaining something. It helps make new memories and move on. Otherwise, we will never progress into the future and cling on everything traumatic we remember. Sometimes we even forget the memories we cherish because this is how the brain works. It lets go of memories so future memories can be made. This is the reason why we even forget our most heartbreaking break up after a while or even our most cherished birthdays.

Here are the three ways it can happen.

Passive Oblivescence

This is the process of losing memory when the neuron connection weakens over time. With aging or when we do not actively recall a memory, the neuron’s link is lost. It can also happen when we lose the stimulus to the mind. The memory might still be there, but we are not able to access it.

Target Forgetting

This happens when our brain actively prunes and discard certain details of a memory. For example, when we learn a new piece of information that contradicts the previous one, the pleasant memory is retained. The conflicted one is dismissed. With target forgetting, we also eliminate our conflicted believes and welcome new perceptions.

Role Of Memory Retention In Daily Tasks

Memory building has a high range of involvement in doing the tasks of daily life. It is mostly dependent on short-termed memory. Ever walked into the room and forget why you came in? Ever forget what were you writing and question you were on during an exam? It has happened when short term memory is not built, and we lose the sense of what we are doing for a while.

Most tasks are process, and we need to actively know and memorize what we are doing every step of the way. How and what you are doing is also important. Thus, things go on in a constant loop. If you do not have short term memory, everything around you will be a giant blur of nothingness. Without short term memory, you will not be able to make long term memories.

Forgotten Memories Are Still In Your Brain

brain

For anyone who’s ever forgotten something or someone they wish they could remember, a bit of solace: Though the memory is hidden from your conscious mind, it might not be gone.

In a study of college students, brain imaging detected patterns of activation that corresponded to memories the students thought they’d lost.

“Even though your brain still holds this information, you might not always have access to it,” said neurobiologist Jeffrey Johnson of the University of California, Irvine. His remarks appeared in the study he co-authored, published Wednesday in Neuron.

That recalling a memory triggers the neurological patterns encoded when the memory was formed is a tenet of cognitive science. Less understood, however, is what becomes of those patterns at moments of incomplete recall.

Maybe you remember breakfast at a certain restaurant, but not what you ate perhaps you recall a particular conversation, but not what you said. It’s not known whether those details vanish from the mind altogether, or are subsumed by some larger pattern, or remain intact but inaccessible.

“It wasn’t quite clear what happens to them,” said Johnson of lost details. “But even when people claim that there are no details attached to their memories, we could still pick some of those details out.”

Twenty minutes later, the researchers showed them the list again, and asked the students to remember what they could of each word.

Treating Tbi Related Memory Loss

Memory loss due to traumatic brain injury may only be temporary, and if thats the case, then simply rest and letting the brain heal should be enough.

However, in cases where the injury is more extensive or there is more significant damage to areas of the brain that handle learning and memory, then you will probably need to figure out a way to manage your memory problems, including:

  • Removing distractions
  • Practicing and repeating information you want to remember
  • Using technology
  • Use to do lists or other visual aids

Emotions And False Memories

A flashbulb memory is a highly detailed, exceptionally vivid episodic memory of the circumstances surrounding a piece of surprising, consequential, or emotionally arousing news was heard. However, even flashbulb memories can have decreased accuracy with the passage of time, even with very important events. For example, on at least three occasions, when asked how he heard about the terrorist attacks of 9/11, President George W. Bush responded inaccurately. In January 2002, less than 4 months after the attacks, the then sitting President Bush was asked how he heard about the attacks. He responded:

I was sitting there, and my Chief of Staffwell, first of all, when we walked into the classroom, I had seen this plane fly into the first building. There was a TV set on. And you know, I thought it was pilot error and I was amazed that anybody could make such a terrible mistake.

Contrary to what President Bush recalled, no one saw the first plane hit, except people on the ground near the twin towers. The first plane was not videotaped because it was a normal Tuesday morning in New York City, until the first plane hit.

Do Something Different Repeatedly

How Does Your Memory Work?

Think back to when you were three years old. You surely were strong enough to hold a knife and a fork just fine. Yet, when you were eating all by yourself, you were creating a mess.

It was not a matter of strength, you see. It was a matter of cultivating more and better neural pathways that would help you eat by yourself just like an adult does. And with enough repetition, you made that happen!

How does this apply to your life right now?

Say you are a procrastinator. The more you dont procrastinate, the more you teach your brain not to wait until the last minute to make things happen.

Now, you might be thinking, Of course, if only not procrastinating could be that easy!

However, , you will start creating those new precious neural pathways.

If you have been postponing organizing your desk, just take one paper and put in its right place. Or, you can go even smaller. Look at one piece of paper and decide where to put it: Trash? Right cabinet? Another room? Give it to someone?

You dont actually need to clean up that paper you only need to decide what to do with it in order to train your brain.

Thats how small you can start. And yet, those neural pathways are still being built. Gradually, you will transform yourself from a procrastinator to an in-the-moment action-taker.

Ms And Dementia: Can You Have Both

Yes, itâs possible to have MS and the more severe dementia, such as Alzheimerâs disease. Changes to the brain can be caused by both MS and Alzheimerâs disease.

People with relapsing-remitting MS, primary progressive MS, secondary progressive MS, and even very mild MS can go on to develop Alzheimerâs disease too. One reason for this may be that treatment advances help all people with MS live longer. In older age, dementia is more common for everyone.

Severe cognitive changes in people with both dementia like Alzheimerâs and MS are probably due to their Alzheimerâs, but progressive MS could play a role too.

Because MS usually causes mild cognitive impairment, donât assume you have early dementia if you have some memory losses or thinking changes. Talk with your doctor about tests you can take to measure your cognitive changes to screen you for early Alzheimerâs or other types of dementia.

Do Activities That Require Focus And Attention

We are curious creatures by nature. Our brains always require a lot of exercise to stay well and healthy. Fortunately, these days it is so easy to arrange. Numerous apps, games, and activities can train your memory in the form of a game or learning a new skill. In fact, you can simply play board games or chess every once in a while to give your brain enough exercise. Learning languages is another great tool for brain training. People who speak two languages or more reduce their chances of having any form of memory impairment, including Alzheimers.

Foraging For Froot Loops

To study a complex human behavior, such as remembering appropriate information at the right time, Eichenbaum had to train rats to memorize an important piece of information and then find a way for them to use it. So his team trained rats to find Froot Loops in flowerpots. Rats are absolutely nuts about Froot Loops, he says.

For example, the rats learned that in room A the cereal is hidden in a pot filled with purple plastic beads that smell sweet. But in room B, the goods are in the pot filled with black paper shreds that smell spicy. Rats are great with odors and textures, so were using textural and olfactory cues to direct them to express their memory, says Eichenbaum.

As the rats navigate from room to room, Eichenbaums team records their brain activity using electrodes inserted into the brain. They monitor both the hippocampus, known to be the seat of memory in the brain, and the prefrontal cortex, thought to be a coordinator.

For instance, when the rat enters room A, the ventral hippocampus transmits to the prefrontal cortex, setting the context to room A. The dorsal hippocampus begins firing as it recognizes flowerpots. The prefrontal cortex, which knows that the reward in room A is in the pot with purple beads, sends this information to the dorsal hippocampus, telling it which memory to act on. The two regions operate together as a system, kind of like handshaking, says Eichenbaum. Were seeing at the level of neurons what happens in cognitive life.

Memories Are Triggered By Senses

Brain &  Memory

We now know that the memory comprises of several chunks of information. The more the sense and emotions involved, the easier it will be to access the memory. In the film Ratatouille, when Remy feeds Ratatouille to Anton, the critic gets a flashback of his mother. It shows Anton as a child, eating the same dish that was made by her mother.

This is a clear depiction of how memory works. The taste of a sensory trigger brought the memory of Anton’s mother. Thus, consciousness is based on several such connections. Similarly, a smell of perfume or a song can also take you to a trip down the memory lane because sensory stimuli are involved in accessing a certain memory.

The Benefits Of An Artificial Brain

Of course, the brain cannot ever be completely characterized in terms of a computer because in addition to all its computing faculties it possesses the properties of a biological organ in a living system. But, points out Gerald Edelman of the Neurosciences Institute at Rockefeller University, computers can indeed do something that, until recently, only a brain could do: they can carry out logical functions. Today, a computer can address any challenge or problem that can be described in a logical formula. This still leaves unexplored vast areas of human experience, such as perception but as described earlier in this chapter, computer and mathematical modeling on one side, and more detailed neurobiological examination on the other side, are making inroads in this area too.

An important principle of Darwin III’s nervous system is that the strength of the synaptic connections can increase selectively with greater activity when that activity leads to an adaptive end. What is ”adaptive” for Darwin III is defined by arbitrary values built into its programming. For example, the built-in principle that light is “better” than no light serves to direct and refine the system’s eye movements toward a target. Just as in living neurons, the enhanced connection provides a stronger response the next time that particular neural pathway is active.

Dementia Is More Severe

Mild cognitive impairment in MS isnât the same as dementia, which is more severe.

Dementia is caused by damage to nerve cells in your brain. In dementia, you have more nerve cell damage and mental declines that are seen in normal aging.

Dementia can cause these symptoms:

  • Getting lost in familiar neighborhoods
  • Problems with speech, reading, writing, or understanding conversation
  • Using the wrong words for simple objects
  • Loss of interest in life or concern for other people

Dementia symptoms get worse over time. Cognitive changes like memory loss may be mild at first, but they usually worsen in just a few years.

People with MS often have cognitive symptoms during a disease flare, also called an exacerbation or relapse. In MS, cognitive changes tend to progress gradually and slowly. Once you have cognitive impairment, usually it doesnât get much worse or cause dramatic changes in how you think, react, or function.

What Part Of The Brain Is Responsible For Learning

To be fair, there isnt really a single part of the brain that affects learning. There are some parts of the brain, especially the hippocampus, that are crossroads for most information, but we still cant say that there is one region that does all the work.

As a matter of fact, all parts of our brains work together in the processes of learning and memory and all of the regions work together to utilize the task.

When we visit a friend or go to the beach, our brain stores a short-term memory of the experience in a part of the brain called the hippocampus. Those memories are later consolidated that is, transferred to another part of the brain for longer-term storage.

A new MIT study of the neural circuits that underlie this process reveals, for the first time, that memories are actually formed simultaneously in the hippocampus and the long-term storage location in the brains cortex. However, the long-term memories remain silent for about two weeks before reaching a mature state.

This and other findings in this paper provide a comprehensive circuit mechanism for consolidation of memory, says Susumu Tonegawa, the Picower Professor of Biology and Neuroscience, the director of the RIKEN-MIT Center for Neural Circuit Genetics at the Picower Institute for Learning and Memory, and the studys senior author.

The findings, which appear in Science on April 6, may force some revision of the dominant models of how memory consolidation occurs, the researchers say.
