Our Brain’s Mysterious Glial Cells

New experiments with the brain’s glial cells have shed light on some of the most mysterious aspects of the mind. Glial cells make up nearly 90 percent of cells in the brain.

Until the last 20 years, brain scientists believed neurons communicated to each other, represented our thoughts, and that glia represented the cement  holding the brain together.  They were considered to be mere insulators for neurons.

But recently scientists have begun to focus on a particular type of glial cell – astrocytes — that are very abundant in the cortex. Interestingly, we humans have the most, and the biggest, astrocytes in our cortex.

Scientists have discovered that astrocytes are the adult stem cell in the brain. They also communicate among themselves via calcium waves, and are  capable of sending information to neurons. They also control blood flow to important regions of activity in the brain.

Harvard University’s Stephen W. Kuffler was the first to discover that astrocytes exhibit an electrical potential, much like neurons. Since then many researchers have completed experiments on the ability of glial cells to communicate with neurons, and have discovered that glial cells respond to and release neuro transmitters just like neurons.

Astrocytes monitor neurons and can induce neurons to fire, and therefore modulate neuron behavior. Neuronal activity without astrocyte processing is a simple reflex — anything more complicated might require astrocyte intervention. This could mean that the calcium waves created by astrocytes are our thinking mind.

Could Your Brain Be Starving?

It’s easy to forget that your brain is a physical organ.

And it has certain physical requirements that must be met, if it is to function well.  If your brain doesn’t get the water and food it needs, it will NOT operate efficiently.

Not only will you not be as smart as you could be, your memory and judgment will also suffer. The results can vary from mildly irritating to truly disastrous.

For example, your 3-pound brain uses as much as 25% of the water you consume. Scientific studies have clearly shown that only 10% dehydration can reduce your measurable intelligence as much as 50%.

One glass of water may stand between you and 50% of your potential brain power.

Your brain also has a great need for fuel, just like your muscles and your bones. Your brain’s most basic food is glucose. If you eat a well-rounded diet not fast-food, chances are you’re providing your brain with a good supply of its basic fuel.

BUT… if you suffer from chronic stress, most of that fuel is going elsewhere. Stress literally starves your brain, kills brain cells, and reduces your potential brain power.

The stress response releases a natural biochemical called cortisol. Cortisol grabs your brain’s glucose then uses it to adapt your body to whatever is causing your stress it physically prepares your body to either fight or run.

That’s why it’s so hard to think clearly when you’re stressed. Ever run in circles trying to find your car keys when you’re in a big hurry?

Chronic stress, in turn, leads to the very real physical sensation of brain exhaustion.

Take the following steps to optimize your brain:

1. Make a commitment to eat properly. Provide your brain with a steady supply of healthy foods.

2. Drink adequate water: Coffee, tea and soda do NOT count. Eight glasses a day is truly the minimum. Remember, your brain needs 25% of that water just for itself.

3. Manage your stress: Find some way to take control of any chronic stress. Don’t kid yourself about this. Stress KILLS brain cells. Take a break every hour or so, and let your brain do some recovery work.

4. Take good vitamins or brain supplements: There are many valuable natural brain supplements available today. Add one to your daily diet for a mental boost and faster recovery from mental and physical stress.

A 2-Day Change Your Life Strategy

You hear stories about people who are on the edge of a cliff, but suddenly turn their lives around.

How do they do they suddenly change their life?

We all know we can’t expect success by doing the same things that have led us to the cliff’s edge. This is basic. So we can assume at least one thing – something changed for these people.

If YOU are ready for a positive and empowering change in your life, here’s a simple plan of action that will get you there with the least amount of struggle or pain…

STEP ONE
First, select ONE lifew change goal you sincerely want to accomplish over the next 30 days.

Make it a SINGLE goal, not a collection. Write your goal right now on paper and include exactly what you want. Follow the below format in writing your goal:

If your goal is financial, it might go like this: “By the first day of December 2009 (specify the exact date), I will have in my possession an additional $5,000, (The exact amount) which will come to me between now and then in various amounts. In return for this, I will do whatever is necessary and appropriate in my business (describe your business, or the business you intend to create).”

Second, now spend at least 30 minutes creating a mental picture of having achieved your goal by December 1st. Remember… you are creating a picture you want your brain to clearly recognize and remember. So… close your eyes and make it as emotionally vivid and intense as possible. Use all of your senses (smell, sight, touch, hearing and taste) to create a mental picture.

Third, read aloud your goal and re-create your mental picture twice a day every day between now and December 1st. Commit to do this! Especially good times are the first thing when you wake in the morning, and a few minutes before bedtime.  Give your mind a target, and it will do its best to hit it.

STEP TWO
Next comes the part of success most people skip – translating your goal into IMMEDIATE action.

Most people’s goals are actually nothing more than a wish or desire. Because of this, their goals are seldom achieved. If you REALLY want to achieve a goal you must take ACTION.

First… a 2-Day Challenge. Fold the piece of paper you wrote your goal on to divide it into two sides. On the left side list 5 things you can do to move toward your goal. On the right side write the exact time over the next two days you will take action on this item. Briefly describe exactly what that action will be.

Next, go to work on your first task. Get it done! Do not let procrastination take over.

Then, at the end of your 2-day challenge, spend an hour or two to plan your next 2-day challenge. The satisfaction you will feel from completing the first 2-day challenge will carry you into the second, and do on until you reach your goal.

STEP THREE
Getting what you want is basically one successful 2-day challenge after another. So…why doesn’t everybody do this? For every 100 people who read this article, only 1 or 2 will actually do it.

Why? Although almost everyone wants to succeed, only a few are truly willing to COMMIT to their goals.

• Are YOU ready to commit to YOUR goal?
• Are YOU ready to make some CHANGES to do so?
• Are YOU ready to truly TAKE ACTION?

STEP FOUR
If YOU are one of the few who is ready to go for it, here is one more tip:

Conduct a review of your current thoughts! You need to take charge of the internal messages your subconscious mind is broadcasting.

Failure to pay attention leaves your subconscious mind in control. Then your subconscious mind will simply continue to reinforce the same thoughts that created the reality you want to change

This takes no special abilities, intelligence or talent. No matter what your past or present situation, or how many times you might have failed to reach your goals, you CAN change things by simply paying attention to the thoughts streaming through your mind.

Give this strategy a try, and watch your reality shift! Change your thinking, and you change your life. Want to speed up the process by applying neuroscience insights? Break loose of your old limitations==>>Make a Change NOW!
