The Mystery Of Human Memory

Memory is an integral part of human life. This can be defined as one's potential to store, retain and consistently retrieve information. For years, experts in the field of medical science have been studying and researching to find ways to enhance memory.

A lot has gone into the study of how human memory works. Experts feel that the more you learn about your memory, the better understanding you can develop in order to improve it.

There are several things we don't forget in our lives such as our crucial school days, summer holidays, some of the tales by granny, the scent of earth when it rains, first love and a lot more. These are the memories that make our life happier.

There are also certain bad memories associated to our lives and we tend to store them in our brain for a long long time. These memories are some of the experiences that allow you to be a different person.

In modern times, experts believe that memory is complex. The memory of anything in your life or day to day activities can be referred to as a 'complex constructive power'. Everyone possesses one. These are certain impressions coming from a pattern of cells that's similar to a web. These cells are scattered throughout the brain.

Experts believe that the memory is made up of a group of several systems. Each system plays a different role when it comes to creating, storing as well as recalling memories. As soon as the brain starts processing information, all the systems mentioned above start functioning together in a perfect manner in order to provide a combined thought.

What we actually visualize as a single memory is a complex engineering. Whenever you think of an object; for instance a toy, all your brain does is to retrieve the name of the object, its' function, shape and sound each time it plays or you take it in your hands. Every section of your memory describing at a toy is, derives from a totally different area of the brain. The whole image of toy is created by the brain from several regions of the brain.

Whenever you ride a bike or drive a car, a particular set of brain cells brings out the memory of operating the vehicle from starting till the end. When there are several things involved such as remembering how to ride a bike, the nervousness as a heavy vehicle passes by etc. comes from all parts of the brain. Experts have come to a conclusion that there is no solid distinction between the way you remember and the way you think.

Of course, the experts have come to a conclusion of how a system actually works. However, it is still not clear about how one remembers or what generally happens when one recalls.

The good news is that there are several things you can do to enhance your memory. There are several exercises, programs and techniques you can follow such as playing riddles, puzzles and several other activities that challenges your brain.

Human memory is a mystery but enhancing one is not!

Guide on the Toughest USB Memory Sticks Available

USB thumb drives-from relatively humble beginnings-have become an essential PC component for both student and road warrior alike.

Ubiquitous and ever cheaper, its success lies in its small size, ever-increasing capacity, and flexibility; they are perfect for quick backups but can boot smaller operating systems as well. Best of all, USB drives are solid state, with no moving parts to break when thrown in a backpack - or a back-pocket. With prices diminishing as capacity grows, a specialized sub-market continues to grow for discerning consumers who desire capacity, throughput and rugged build quality.

This niche market is well served by the following rugged USB drives released over the last few months.

First up is the Verbatim TUFF-CLIP. Featuring 8GB of storage, the TUFF-CLIP, as its name implies, boasts a clasp on one end - perfect for belt or laptop bag loops. Considering that the size of USB thumb drives can sometimes be a mixed blessing-easy to carry, but likewise also easy to misplace-its closable clasp is a minor but nonetheless needed innovation. This plastic also sheathes the rest of the drive without sacrificing portability. The drive itself is optimized for ready-boost speed for Vista and Windows 7 users and features the now standard security software onboard. The Verbatim TUFF-CLIP comes in at a competitive price point compared to its more vanilla competitors. The clasp is well integrated with the rest of its casing.

Priced similarly, but featuring a tougher exterior is a new player in the market: the ATP ToughDrive. ATP advertises SIP technology in a drive that is shockproof, waterproof and dust-proof. Such claims might well cover all but the cheapest USB thumb drives; when picking up at a recent computer trade show, I immediately understood the market ATP is looking to snare. Like the TUFF-CLIP, the ToughDrive features a tough shell encasement, but with a dense rubber as opposed to the more common plastic. Unlike some its competitors, it seemed welded onto the drive. While its design does not include a clip, the ATP felt light in the palm while undeniably tough. Ridges on both sides of the drive, including a removable tip, were a nice touch; they added heft while not detracting from overall portability. The ToughDrive ships in 4GB and 8GB and the drive itself includes the ready-boost and security options now standard for higher-end thumb drives. The drive itself, as will all of these featured here, is sturdy and well embedded in its casing.

One would think that the military is one step ahead of the rest of us in thumb drive innovation. They probably are. But other professions with truly mission critical needs have developed a market with a new twist on tough. Meet the TAC drive. Eschewing industrial-grade plastic or rubber, the TAC drive is encased in light-weight metal that nonetheless meets-and exceeds-military field regulations. Weighing less than an ounce, rural and suburban fires led physician Dr. Anthony DuBose to conceive of a tough, but lightweight thumb drive that could withstand extreme conditions while saving important medical information of the firefighters engaged in fighting the flames. The result is a thumb drive capable of withstanding freezing in dry ice, submersion in a hundred feet of water, when not heated to degrees exceeding 250 degrees Fahrenheit.

The price is competitive with the other drives listed here, but the capacity is indeed smaller at 1GB. Still, this is an attractively priced, and truly archival quality drive, ready to bear the brunt of extreme elements. A drive tested in a forest fire seems well worth trusting irreplaceable information with; overlook its unsexy, Swiss knife design and it becomes a portable, and fireproof safe - ready on the go.

Rugged, tough USB drives should not resemble a Hummer in miniature; consider instead the materials and intelligent design that go into a high-end, tough USB drive. Form factor, design and on board software are all features to consider when shopping for a tough USB drive designed to withstand the tests of time, circumstance and environment.

What Your Doctor is Prescribing Could Be Robbing Your Memory - Part II

In Part I of Memory and Aging, I explained to you how growing older can affect your memory. I also gave you some brain-healthy things you can do to keep that incredible shoulder-top computer retrieving all its data well into your advanced years.

Here in Part II, I would like to talk to you about prescription drugs, and the impact they can have on your brain function and your memory. Then we'll talk about some natural supplements and how they can help you retain more of your memory.

Each category of prescription drugs has a multitude of individual drugs that can be prescribed to you for common ailments like sinus problems, infections, insomnia, nausea, etc. The effects on your memory can range from temporary short-term memory lapses to broad, long-term memory wipe outs.

In the list below, I've included the types of prescription drugs that can damage your memory.

PRESCRIPTION DRUGS THAT CAN CAUSE MEMORY LOSS

Analgesics
Anesthetics
Antianxiety
Antidepressants
Antibiotics
Antihistamines
Antihypertensives
Anti-Seizure medications
Hormones/steroids
Nausea Drugs
Parkinson Disease Drugs
Sleep Aids
Ritalin
Statins

Mother Nature To The Rescue

With all the pharmaceutical drugs out there that threaten to damage your brain and your memory, the good news is that there are several vitamins and natural, herbal-derived products that have brain-health preserving and memory boosting properties!

The most significant group of vitamins that enhance brain health and memory are the B vitamins, especially B6, B9 (folic acid), B12, citicoline. B vitamins protect the nerve sheath covering brain cells. They pulverize homocysteine, a nerve cell toxin, and carry oxygen. A healthy diet filled with citrus fruits and dark green, leafy vegetables, and/or supplement, aids good brain function.

Next, antioxidants like Vitamin C, E, and beta carotene, give critical protection to brain tissue by dissolving free redicals that cause damaging oxidation. These nutrients can be found in citrus fruits, yams, and wheat germ/oil and are also a staple of good vitamin supplements.

Beneficial fatty oils, like Omega-3 fish oil, help protect the brain cells by neutralizing inflammation and cholesterol deposits. Fatty fish like salmon or fish oil supplements of 1,000 mg a day ensures optimal brain levels of this nutrient.

Below, I've listed several, herbal-derived supplements that are beneficial to your memory.

NATURAL SUPPLEMENTS THAT HELP IMPROVE MEMORY

Alpha GPC - supports attention, focus, recall, and other brain functions.

Adenosine Triphosphate (ATP)- supports concentration and focus.

CoQ10 - helps with overall body energy, supports concentration and memory.

DMAE - helps with alertness and concentration.

Gingko biloba - improves blood/oxygen flow to the brain.

Huperzine A - aids age related memory loss; boosts short-term memory.

L-Carnitine - an amino acid that aids brain energy.

L-Glutamine - works as a brain transmitter, aids concentration and alertness.

Lion's Mane Mushroom - enhances mental performance. Aids in nerve/brain cell growth.

Vinpocetine - improves blood flow to memory storage center of brain.

What You Can Do

As I've discussed here, you don't have to be resigned to memory loss. There are some excellent natural sources of supplements, as well as vitamins, available that can help keep your brain and memory functioning optimally.

If you take any of the classes of prescription drugs noted here and seem to be experiencing memory problems, please contact your physician to discuss your concerns.

4 Simple Steps To Boosting Your Memory And Mental Clarity

[An exclusive interview with George Foss, former general manager of Kayser Nutrition, southern California's health food store chain to the wealthy and famous for 52 years. George has been called a "walking repository of nutritional supplement research knowledge," and is a long-time consultant to the nutritional supplement industry. Featured on a variety of television and radio news broadcasts over the past 20 years, he is widely considered by west coast news media outlets to be the nutritional supplement industry's "go to" guy on natural health topics.]

Steve Barwick: George, I understand you are going to reveal four simple steps readers can take to boost their memory and maximize mental clarity with Vinpocetine. We'll get to that in just a minute. But first, could you tell us a little bit about the history of Vinpocetine, and help us understand how it works, and what it actually does to enhance brain function and boost memory and mental acuity?

George Foss: Yes, certainly. While Vinpocetine is a popular nutritional supplement here in the U.S., in Europe it has been widely researched and used clinically as a prescription drug for over 25 years, particularly in the prevention and treatment of common senility, as well as for senile dementia or Alzheimer's disease. It has also been used to help prevent and treat cerebral arteriosclerosis, which is a hardening of the arteries of the brain. Because it is basically a modified alkaloid from the Vinca major plant, which is the common Periwinkle plant, it qualifies here in the U.S. as a dietary supplement under the Dietary Supplement Health & Education Act of 1994. And it has been legally sold here without a prescription since shortly after Congress passed the Act. This aggravates the FDA and the U.S. drug companies to no end, of course. But it is wonderful for the American public because it gives them such easy access to this very powerful and beneficial brain-boosting nutrient. I mention its prescription drug status in Europe only because this means it has been widely studied for many years, and its safety and effectiveness have been demonstrated beyond any shadow of a doubt.

Steve Barwick: How does it work?

George Foss: Vinpocetine dramatically enhances the metabolism, or energy activity, of the brain. It does this in part by increasing blood flow to the brain through vasodilation, which in turn maximizes glucose and oxygen uptake by the brain's 100 billion neurons. The neurons thrive on glucose and oxygen, which they use to produce prodigious quantities of adenosine triphosphate, or ATP. This in turn boosts the energy activity of the entire brain, which of course, is the supercomputer of the human body. This increased energy activity then triggers three crucial functions in the brain: repair or replacement of damaged brain cells, increased electrical activity between the neurons, and enhancement of efficient cell-to-cell communication. In other words, ATP is crucial to all major aspects of brain function. It helps keep the brain healthy and in peak operating condition. And Vinpocetine enhances the process by dramatically increasing the brain's ability to produce ATP. This is, in large part, why Vinpocetine has been used so successfully in the prevention and treatment of everything from simple memory disturbances to common senility, senile dementia and strokes. It has some very positive effects upon damaged areas of the brain. And its antioxidant properties are believed to help further protect the brain from premature aging, by mopping up free radicals before they can damage brain cells. What's more, because Vinpocetine helps increase brain levels of ATP quite dramatically, you also get a very pleasant mental lift from it.

Steve Barwick: Wow. That's a quite a lot of powerful benefits. So how can readers use Vinpocetine more effectively, specifically in terms of boosting memory and mental clarity, and protecting the brain against the ravages of aging?

George Foss: There are a number of steps Vinpocetine users can take to more effectively protect and nourish the brain in order to help maintain cognitive function at peak levels throughout one's life. They are as follows:

1.) Dosage -- Using Vinpocetine correctly is the single-best strategy. Research suggests that healthy individuals who simply want to use Vinpocetine for its protective anti-aging benefits on the brain, and to boost memory and mental clarity, should take one 10 mg. capsule per day, with food, first thing in the morning. The vast majority of people fit into this category, and will find Vinpocetine to be very helpful. However, if a reader is already experiencing mild memory problems and wants to use Vinpocetine to help restore brain function to more youthful levels, he or she may need to take two 10 mg. capsules per day for maximum benefits. For moderate to severe memory problems, a person may need to use three capsules per day. Of course, you should never self-treat serious health problems, such as senile dementia. And important health care decisions should always be made under the guidance and supervision of a knowledgeable and experienced health care provider.

2.) Exercise and Rest -- You can increase the beneficial effects of Vinpocetine through mild daily exercise, such as walking. Exercise boosts brain power significantly, particularly in the elderly, as just about every study on this subject has shown. That's because mild daily exercise increases blood flow to the brain. And of course, increased blood flow provides the brain with additional oxygen and glucose, the brain's two primary fuel sources. Since Vinpocetine acts as a potent vasodilator, which means it increases the capacity of the arteries in the brain to carry increased blood flow, a nice long walk in the morning or afternoon will help dramatically maximize its well-known brain-boosting benefits. What's more, you should never underestimate the power of a good night's rest for maximizing mental clarity. For most people, the single-greatest robber of brain function is lack of sleep. Study after study has confirmed that planning, problem-solving, learning, memory, concentration and alertness are all dependent upon getting plenty of rest. The brain needs it. So you should always do your very best to get at least eight hours of sleep per day. No amount of Vinpocetine, or any other nutritional supplement for that matter, can overcome the deleterious effects of long-term sleep deprivation on the brain. And a well-rested brain is more receptive to the energy-boosting actions of Vinpocetine.

3.) Proper Nutrition -- From the moment you awake each day, your brain craves nourishment. It is literally the most greedy organ in your body. And while Vinpocetine increases the brain's capacity to receive and effectively utilize vital nutrients, it is not a substitute for those nutrients, any more than it can substitute for the brain's need for plenty of daily rest. So be sure to start each day with a good healthy breakfast that includes a high-quality protein such as eggs, cheese, meat, or even nuts and seeds, to supply your body with plenty of brain-boosting amino acids, choline, and essential fatty acids. Taking a good omega-3 fish oil supplement with breakfast will help supply the brain with specific essential fatty acids such as DHA, EPA and ALA, which have long been linked to a healthy mental outlook and increased cognitive function. Finally, be sure to include some healthy glucose-producing carbohydrates with breakfast, such as oats, whole wheat bread, milk or whole fruit. Then, throughout the day, make sure you get more of the same, including a balanced combination of simple and complex carbohydrates such as vegetables, whole grains, brown rice, peas, beans, potatoes, fruits and milk. These will help your body maintain healthy blood glucose levels, so that Vinpocetine can effectively do its job of delivering glucose and oxygen to the brain for the production of ATP.

4.) Nutritional Supplements - There appears to be a dramatic beneficial synergism between Vinpocetine and other nutritional supplements. So be sure to take a good multi-vitamin/mineral supplement daily. Use one that contains plenty of B-vitamins, including niacin, folic acid, biotin, thiamin, riboflavin, vitamin B-6 and B-12, plus trace minerals such as selenium, potassium, boron, zinc and others. Trace minerals are crucial for proper brain function. For example, low selenium levels have been correlated with poor cognitive function in numerous studies. And low zinc levels have been correlated with faulty memory. Minerals such as potassium and boron dramatically influence the electrical activity of the brain, and skimping on either can significantly decrease mental alertness. What's more, the brain-boosting benefits of B-vitamins have been demonstrated in study after study. In part, that's because all B-vitamins are used by the body to more effectively convert carbohydrates into glucose, the main fuel of the brain. So B-vitamins actually aid Vinpocetine in getting more glucose to the brain for conversion into ATP. As I have mentioned, this in turn boosts repair or replacement of damaged brain cells, facilitates electrical activity to and from the neurons, and enhances efficient cell-to-cell communication in the brain. In short, it turns a lazy brain into a beehive of efficient activity. And it can help keep the brain functioning at more youthful levels literally for the rest of your life!

Steve Barwick: George, that's absolutely fascinating. Vinpocetine is obviously a very powerful and effective supplement, and we appreciate your tips on maximizing its benefits. As always, it's a real pleasure talking with you. We very much appreciate your insights and advice. Thank you once again for taking the time to visit with us.

George Foss: Thank you, Steve. It's been my pleasure.
