High Performance Memory By Pat Wyman, M.A. Article may only be reprinted with express written permission. It's something we all want more of - a great memory. Why? Because it makes our lives easier and even increases our intelligence. We perform better in school, better in life and think faster on the job with a good memory. Everyday facts stay at our fingertips and learning new things becomes a snap! Even as adults, we know that activating our memory and constantly learning new things may very well prevent age related diseases such as dementia and Alzheimer's. So the question is - how do we do it? What does neuroscience say about the possibility of creating a designer brain - one that has an excellent memory? Can we even raise smarter children with great memories? A resounding YES - to all of the above! Keys to A Great Memory Toolkit Let's take a look at what science has learned about memory. After each item, you'll find tips on how to create an extraordinary memory. 1. The Science: Exercise Your Body
for A Better Brain - Exercise positively affects the hippocampus,
a sea-horse shaped brain structure that is vital for memory and learning.
Researchers found that adult mice doubled their number of new brain cells
in the hippocampus when they had access to running wheels. Exercise
alters the molecular mechanisms that are important for learning and memory.
Regular exercise prevents the negative effect of chronic stress on the
brain at the molecular level and boosts the brain's biological battle against
infection.
Neuroscientists will learn how to use "directed neuroplasticity to determine what specific inputs will change the brain in helpful ways. For example, right now we can see on brain scans that brains capable of logic are physically different from brains that are not. The question remains - how do we change the input to help a person become more logical"? Science has now proven that the brain never stops changing and adjusting. This flexibility can even help maintain language processing even in the face of severe obstacles. Researchers once thought that only young brains were plastic and flexible - now we know that the brain retains its plasticity throughout life. This means that even people with specific disabilities and challenges like dyslexia, reading problems and language processing problems can all respond to interventions that modify brain networks. Reading programs that alter neural circuits like Fast ForWard are already improving reading ability by two years during a 6 to 8 week training session. The implications of brain plasticity are almost limitless - it will
mean that schools can deliver education based on neuroscience principles
and that learning isn't only in textbooks. Coaches may soon learn
to use plasticity to create better athletes by improving brain circuitry
and trainers will no longer need to rely on hit-or miss training for anything!
Peak performance is a reality.
Researchers have found that stress hormones like corticosterone,
similar to cortisol, can even block retrieval of information stored in
the brain. Learners in a state of fear or threat not only have a
harder time learning, their immune system becomes depressed and their learning
slows down. The good news - when you're calm, your memory returns.
The mayonnaise you put on your sandwich and the type of dressing you put on your salad may have an impact on your stress levels, moods, impulsiveness and even your ability to learn. (Skip all trans-fatty acids like those found in margarine and most packaged goods. Read the labels- if you see the words hydrogentated or partially hydrogenated, pass them by!) Read on to find out how essential fatty acids, the good omega-3's, affect everyone's brain, including your baby's. Essential fatty acids are components of every cell and are needed for many functions in the body. In fact, one reason the type of fat you eat has such an important effect on your mind is that your brain is more than 60% fat (I guess that makes us all true fat heads)! This is not the same type of fat you see around your belly but structural fat, the type that forms your cell membranes and plays such an important role in how your cells function. Essential fatty acids are found in cold water fish like salmon, fish oils (sometimes hard to digest) and flax seeds and flax oil. The reason these fats are called essential is because they cannot be made by the body. They must be supplied by your diet! If you're like most people, more than likely you won't be able to eat enough of the foods that contain them to get what you need. So, you might want to consider supplementation! As far back as 1930, researchers found that if an animal did not get enough essential fatty acids in the diet, it could cause symptoms such as poor reproduction, lowered immunity, rough, dry skin (like the kind you might notice as little bumps on the back of your arms) and slow growth, among others. The list of benefits from essential fatty acids is enormous:
DHA, docosahexaenoic acid and AA are fatty acids present in human breast milk and prior to birth are supplied through the placenta to the developing fetus. Both DHA and AA are believed to play a role in the development of the nervous system. Fifty six 18 month old children were divided into three groups. One group received formula containing only DHA, while another received DHA and AA. The control group received a commercial formula without either. All three groups were enrolled in the study within five days of their birth and received on of the three formula types for 17 weeks. Overall intelligence and motor skills were tested using the Bayley Scales of Infant Development, 2nd edition (BSIDII). No differences were seen on motor skills, but the children differed significantly on Mental Development Index of the test. It measures memory, ability to solve simple problems and language capabilities. Children in the control group received an average MDI score of 98, slightly below the national average for U.S. Children of 100. The DHA group received an average scores o 102.4 and the DHA plus AA group received an average score of 105! You can read more about this study at www.nichd.nih.gov and it's interesting to note that European baby formulas have essential fatty acids in them and the U.S. is only just now deciding whether to include them in their baby formulas. Apparently, according to Artemis P. Simopoulos, M.D., there is quite a link between omega 3 fatty acids and learning. According to a 1996 study done at Purdue University, 100 boys between the ages of six and twelve were studied. Those who had the highest levels of omega 3 fatty acids had the fewest learning problems. According to information in the book, The
Omega Plan by Artemis P. Simopoulos, M.D., president of The Center
for Genetics, Nutrition and Health in Washington, D.C. and former NIH chair
for the Nutrition Coordinating Committee, the "process of learning and
remembering involves the transmission of various chemicals from one nerve
ending to another. These chemicals are stored in tiny packages called
'synaptic vesicles.' The more synaptic vesicles in a nerve ending,
the more chemicals that can be transmitted. Enriching the diet of
rats with omega-3 oils resulted in considerable more vesicles in their
nerve endings as well as better performance on all their tests. This
study suggests there may be a direct connection between the amount of omega-e
fatty acids in your diet, the number of synaptic vesicles in your neurons,
and your ability to learn."
6. The science: Gingko Enhances Brain Function - You've probably heard of this extraordinary herb as the most widely used prescription medication in Europe. It has the ability in its flavonoids and ginkgolides to facilitate increased blood flow circulation and mental function. Gingko relaxes the blood vessels and inhibits the aggregation of platelets. It's particularly helpful in cases of decreased blood flow to the brain, which is usually age related. Ginkgo, says Julian Whitaker, M.D., works by combating free radicals
and promoting circulation to the tiny capillaries of the brain. A
high quality extract will be standardized to contain 24 percent ginkgo
flavone glycosides and 6 percent terpene lactones. But, he cautions,
be patient. It can take up to three months to work.
Also, memory that has an emotional component or even a smell connected with it is even more powerful and easier to retrieve. (Goleman, Daniel. Emotional Intelligence). Since learning and memory occur when neurons communicate with each other it's a lot easier to access the memory you want when you intentionally store that memory in several different ways. That way you'll be able to use various triggers to retrieve any memory. According to brain researchers, the process of memory is far more important than the location since the brain doesn't just store memory in one location. The point: When you activate a single memory system or memory pathway, you might appear to forget what you know. However, activating multiple memory systems or pathways through a wide variety of activities increases your ability to retrieve what you want. It's a lot like going to a filing cabinet for a single file on a certain subject. If you can't remember where you filed it, but knew you have made several copies and filed them under different headings, you'd be more apt to find the file more quickly. Here are five types of memory or storage and retrieval systems: a. Semantic (categorical) also known as short term immediate and short term working memory. This is where new information comes into the brain and is housed in the frontal lobe of the cerebral cortex. This type of memory is what's currently in focus and can only manage about seven bits of information (plus or minus 2) and lasts only 15 - 30 seconds before it transfers the information into the working or intermediate memory. (See Fire-Up Your Learning by author, Tom Madden). According to Tom, the short term information gets downloaded into long term memories at night during sleep. Semantic memory holds the information learned from words. This type of memory seems to be a difficult one to use for learning because it takes so many repetitions to cement it into the pathway. It also has to be sorted and stimulated by associations, comparisons and similarities to be effective. This type of memory can easily fail us in many ways. b. Episodic Memory. It is easier to access this type of memory according to Marilee Sprenger, author of Learning and Memory. This is sometimes called contextual or spatial memory because you are always somewhere when you learn new information and you can connect the learning with the location. The quickest way to think of episodic memory is to ask, "Where were you when President Kennedy was shot or when you first learned about Princess Diana's death? The reason episodic memory is so important to understand is because children and adults who learn information in one location and are shuttled off to an unfamiliar location to be tested on that information consistently underperform. According to Sprenger, "The content of the room becomes part of the context of the memory." So, when you know you will be tested in another location from the one you learned the information in, try and visit the testing room often, visualizing the information you want to remember in various locations around the room. c. Procedural Memory. This is also known as motor or muscle memory and once a physical task is learned, lasts for years. Procedural memory involves tasks like writing, riding a bike, tying your shoe laces, etc. It works by association and your brain seems to have an unlimited storage capacity for body-kinesthetic memory. Procedural memory is stored in the cerebellum and gives humans the ability to do two things at once like driving and talking. When you want to recall something you learned, return to the same position and do whatever you were doing when you first learned the information. People who like to move around when they are learning can more easily recall the information if they move around in the same way. I know of children who do cheers when learning or skateboard when memorizing their times tables. d. Automatic Memory is known as conditioned response memory. This type of memory is automatically triggered by certain stimuli and is located in the cerebellum. You might hear the first few words of a song and start singing it, remember your multiplication tables or the alphabet here. Your ability to read but not comprehend is in automatic memory. According to Jensen and Sprenger, "Your automatic memory may cause other memory lanes to open." When you hear a certain song on the radio you may remember the words to it and also where you were when you first heard it (episodic) and what events were going on when you first heard it. You may even recall something procedural, like driving your car when the song was playing and better yet, some factual, semantic memory lanes may open up too. Further, hearing the song may even cause you to have an emotional reaction similar to the one you had when you first heard the song. Obviously, automatic memory has great implications for enhancing recall through strong associations. The more memory lanes you can connect with what you are learning, the easier it will be to recall that learning. e. Emotional Memory. This type of memory takes precedence over all others and may even take over your logical mind. Daniel Goleman, author of Emotional Intelligence, (1995) calls this type of response "neural hijacking." Emotional memory is opened through the amygdala, located next to
the hippocampus. While the hippocampus files factual information,
the amygdala stores emotional information. The fear response is stored
here as is happiness, sadness and a host of other emotions. When
learners are feeling threatened, learning abilities plummet. Stress
hormones may simply block access to the facts. Remember, your brain
will always give priority to emotional memory. While you have facts
stored in your semantic memory, how you feel about those facts may affect
your ability to recall them. That is why learning is so much more
effective and efficient when the learner is relaxed and associating things
like humor to the learning. Access to learning is easier in the future
when it is connected to something funny.
