Brain Neuron Microtubles
Microtubules are major components of the
structural skeleton of cells. They exist inside neurons in the human brain and are at the forefront of new research. The recent discovery of quantum vibrations in microtubules inside brain neurons may be related to EEG waves, memory, and consciousness, to name just a few.

Autism
Research on Autism is, fortunately, moving forward by leaps and bounds. New research from University of Toronto and Case Western Reserve University neuroscientists has pointed out that the brains of autistic children generate more information when the brain is at rest; 42% increase on average. The study offers a scientific
explanation for the most typical characteristic of autism, a tendency to withdraw into
one’s own inner world. The excess production of information may explain a
child’s detachment from their environment. Published in Frontiers in
Neuroinformatics (open access), this study is a follow-up to the authors’
prior finding that brain connections are different in autistic children.

Teenage Brain
Many parents are complaining about how difficult it is to get the teenage brain up and going in the mornings. Really? Of course it's difficult. Teenage
brains work two hours behind adult time. They get up later because they are biologically
programmed to do so. Dr. Paul Kelly, author of Making Minds, says that continuous early starts create ‘teenage
zombies’ and that allowing teenagers to begin lessons at 11am has a profound
impact on learning. Rousing teenagers from their beds early results in abrupt
mood swings, increased irritability, and may contribute to depression, weight
gain, and reduced immunity to disease. Advances in brain-function information need to result in practical application--especially where teenagers are concerned.

Arguing and Hormonal Imbalances
Have you ever wondered the reason some people argue? Their tendence to argue can certainly be a stressor for those who interact with them. Hormonal specialist, Dr. Michael Borkin, points out that arguing
impacts the stress hormone cortisol (arguing lowers the levels) as well as the lower range of blood sugar
(arguing raises the lower levels – as opposed to insulin that impacts higher ranges of blood
sugar levels). Some individuals trigger arguments because five minutes of
negative interactions results in a six-hour decrease in cortisol levels. They
are, in effect, self-medicating and tend to argue at 6am, 3pm, and 9pm. When
hormonal imbalances are addressed, arguing tendencies may resolve. That's one reason to deal with hormonal imbalances--for yourself as well as for those around you..

Multilingual Benefits
More and more studies are showing the benefits of being multilingual, which even seem to impact one's rate of aging. When children are born into multilingual households, they learn all the languages to which they are regularly exposed. Infants can learn three or four languages or
more. In the process of learning to speak, there are strong relationships
between speech, song and music. Areas of the brain that are primarily concerned
with music and language overlap considerably. A
person’s native tongue even influences the way in which he or she perceives music.
The same succession of notes may sound very different depending on the language
the listener learned growing up. Some suggest that children learn multiple languages more effectively when each parent selects one language in which to communicate with the children (e.g., Dad always speaks English, Mother always speak Russian; Mother always speaks English, Grandmother always speaks Spanish, Father always speaks Italian). This appears to impact both speed of learning and retention.

Exercise - Longer May Not Be Better
How much physical exercise do you really need? You definitely need some every day. How much time do you need to devote to physical exercise every day? Opinions differ. According to Dr. Borkin, studies
have shown that physical exercise beyond 42.5 minutes can have a negative
response on cortisol levels (cortisol is one of the stress hormones--you need some of it lp you manage stressors effectively; too much cortisol can cause all manner of havoc in the brain and body). Knowing this, Borkin recommends exercise for only 40 minutes at a
time. If you want to do more, wait at least 20 minutes before restarting
exercise. (Borkin, Michael, PhD. Sabre Sciences, IncTM. Lecture,
January 2014)

Brain and education
According to Ken Robinson Sir, PhD, in Out of Our Minds, the purpose of education is to:
Develop individual talents and sensibilities
Deepen the student’s understanding of the world
Provide the skills required to earn a living and be economically productive.
Develop individual talents and sensibilities
Deepen the student’s understanding of the world
Provide the skills required to earn a living and be economically productive.
The challenge now is to transform education systems into something better suited to the real needs of the 21st century. At the heart of this transformation there has to be a radically different view of human intelligence and of creativity.

Imagination
Recently I've had several questions about the importance of imagination, some from unenlightened adults who accuse children of "lying" when using their imagination (That happened to me as a child when I made the colossal error of telling some adults about my imaginary friend: Little John Deerfoot.) In Out of Our Minds, the author explained the function of imagination this way:
"Imagination,
the primary gift of human consciousness, is the ability to bring to mind things
that are not present to our senses. Creativity is applied imagination, putting
your imagination to work. Innovation is applied creativity, putting new ideas
into practice. Creativity is the process of having original ideas that have
value."
Imagination can be honed or suppressed . . . honing it takes practice, which can begin very early in life as children "pretend" play . . .

Our Minds. P 141-143, 151. NY:Capstone Publishing Ltd, 2001, 2011)

Power of "No"
The
power of “no” is poorly understood. It's so poorly understood that I've written an article about it. There is a difference between the ability to use "no" powerfully and a negative mindset. Negativity is an ongoing attitude. NO is a moment of clear choice. It
announces, however indirectly, something affirmative about you. Wielded wisely,
“no” is an instrument of integrity and a shield against exploitation. It often
takes courage to say. It is hard to receive. But setting limits sets us free.
If you feel you can’t say no at least
to some things, some of the time, then you are not being loved—you are being
controlled. No is a shield. Therein
lies its power. The ability to say no makes
your yes much more meaningful. (Sills, Judith, PhD. “The Power of NO!”

November/December 2013)

Mindset
People sometimes say: "You keep talking about mindset; what's so big about mindset?" Typically I reply: "Everything starts and ends in the brain." According to Dr. Dweck, there are two clear types of mindsets and the way in which you lead your life is profoundly
impacted by the mindset you adopt for yourself. A fixed mindset (a belief that
your qualities are set in stone creates an urgency to prove yourself over and
over); A growth mindset (a belief that your basic qualities are things you can
cultivate through your efforts. It’s not that anyone can become anything but
that one’s individual potential is unknowable and that it is impossible to
foresee what can be accomplished with years of passion, toil, and training).
The fixed mindset makes you concerned with how you’ll be judged; the growth
mindset makes you concerned with improving. You can change your mindset.

Tactile Illusions
Most people are familiar with and often enjoy visual illusions. The kinesthetic sensory system has its own type of illusions. One type is known as tactile
illusions. They relate to the sense of touch. I recall my mother
(who loved to wear hats), removing her chapeau at the end of the day and then
briefly touching her head with her hand. When I asked her the reason she
touched her head she laughed and said, “For a moment it felt as if the hat was
still on my head.” Some of you may have experienced a similar illusions. Here's another: Hold one hand in a pan of very cold water and place the
other hand in a pan of quite hot water (not hot enough to get burned!). Hold
them in this position for at least a minute or two. Now remove both hands and
immediately submerge them in lukewarm water. If you’ve done this experiment,
you likely found that the lukewarm water felt hot to the hand you had submerged
in cold water while the lukewarm water felt cold to the hand you previously immersed
in hot water. A tactile illusion.

Wagon-Wheel Illusion
Most
of you likely have observed the wagon-wheel illusion in real life. It is an optical illusion in which a wheel
with spokes appears to rotate differently from its actual rotation. If
you’ve not observed this, I like the example and explanation provided at the
link below. Reportedly, the illusion was first
noted during the playback of old movie films in which the wheels of a
forward-moving vehicle appear to slow down or even roll backwards. Some have
noticed this in recordings of helicopter rotors and aircraft propellers. The effect is said to be a result of
temporal aliasing. It can also often be seen when a rotating wheel is
illuminated by flickering light. These forms of the effect are known as
stroboscopic; the original smooth rotation of the wheel is visible only
intermittently.

Almonds, Heart, and Brain, #2
What
does reducing your risk of heart disease have to do with brain function? A lot
more than many people might think. First, your heart is responsible for
circulating blood throughout the body—including to the brain—on a regular and
timely basis. The blood brings oxygen, glucose, fluids, and micronutrients to
the brain. The blood also removed waste products from the brain (ongoing
housekeeping, if you will). Anything that interferes with the blood supply or
with the quality of what it brings to the brain potentially can decrease brain
function. And if you want to keep life in your years and live as many quality
years as possible, it matters! Some are referring to almonds as a superfood. I eat a few raw or dry
roasted almonds almost every day.

Almonds, Heart, and Brain
Can almonds reduce the risk of heart disease? Apparently
they can—according to a study led by Professor Helen Griffiths, Professor in
Biomedical Sciences and Executive Dean of the School of Life and Health Science
at Aston University, Birmingham, UK. The goal was to evaluate the effects of a
short-term trial of eating almonds on reducing the risk of heart disease. A
control group of healthy males ate what they would normally eat, the test group
of males with cardiovascular risk factors including high blood pressure or
being overweight ate snacks of 50 grams of almonds (slightly under two ounces;
1.76 ounces to be more precise) every day for one month. Did it make any
difference? At the end of the study period, the test group showed higher
blood-levels of antioxidants, lower blood pressure, and improved blood flow;
all of which potentially reduce one’s risk of heart disease. Part 2, tomorrow.

Fear vs Gratitude and Napa Quake
As you may know, the Napa Quake 6.0 left many with a mess to clean up. Friends of mine offered to drive out and go into my house with me to survey the damage. When I unlocked and pushed open the door and saw all the smashed glass and china and pressed alabaster statuary and blown out windows, I started trembling and felt tearful from the shock. That is a typical reaction to shock; the trembling muscles actually helps with the recovery (if someone doesn't realize this the tendency is to try to get the person to "stop trembling,' which can interfere with the recovery). Within just a minute or two, however, my brain reminded me that "fear and gratitude cannot exist simultaneously within the brain. Recalling that, I immediately began to think of things for which to be grateful (e.g., we were all safe and uninjured, the house neither fell down nor burned up, my friends were helping me clean). Two minutes later I was no longer trembling or tearful and had energy to jump in and start the the process. I frequently say that brain-function information, practically applied, can be life-changing. This was an opportunity to use the information--and it definitely gave me a positive outcome.

Gender Brain Differences, 5
I
spoke recently at a parent-teacher meeting and described how empowering an
apology can be, especially in a parent-child or teacher-student relationship, when
you have learned new information that is prompting a change in your behavior. (No
one can know everything so stop expecting that you do!) At the break, a small
entourage approached me to say they thought ‘actions speak louder than words,’
and that no verbalization should be necessary, just a change in behavior. My
brain has a different opinion. You are role-modeling not only a change in
behavior based on something new you learned but also bringing it to the
children’s/student’s conscious awareness so they know you are deliberately
implementing your new knowledge in a change of behavior. After all, you can
only do better when you know better. What do I say? “I regret telling you to
put down your toys and be still while I read to you (or telling you to look at
me when I’m talking to you). I have learned there is a better way and I want
you to know I’m altering my behavior. You can play quietly with your toys while
I read (or you never have to look at me while I’m talking to you).” Being
intentional, in my brain’s opinion, usually includes some brief role-modeling
verbalization about what you learned that is triggering your change in
behavior.

Gender Brain Differences, 4
Recently,
a mother told me: “After listening to one of your presentations, I went back
home and apologized to my 15-year-old son for telling him to stop fiddling and
to look at me—for pretty much his whole lifetime--when I talk to him. He said,
‘Mom, when I fiddle with something I hear and really listen to every word you
say. When you make me stop and be still and tell me to look at you, I shut down
and don't remember a thing you say.’ My son and I both thank you. It’s been two
days and our relationship is already better How come I didn’t know this
sooner?” That’s one example of the reason I try to share current brain-function
information with anyone in any way and anywhere I can. In this case, her son’s
response does align with current research on differences between males and
females. This is especially important when conversing with boys. It is often so
much more effective to just sit down together, side by side, and chat while he
is “doing” something. It can be as simple as playing with a Lego toy or running
a little model car up and down his thighs or over the arm of the sofa or
however an older boy wants to “fiddle.” Part 5 tomorrow.

Gender Brain Differences, 3
When
conversing with each other, females often stand or sit directly across from
each other and use a great deal of eye contact. Because they are so comfortable
doing this, they have a tendency to tell males to “look at me when I’m talking
to you.” When conversing with each other, males rarely stand or sit directly
across from each other by choice, and use very little direct eye contact. This
means that males often feel threatened by a female demanding that they look at
her during a conversation. This is especially true during emotion-laden
conversations. The take away? Females, stop telling males to look at you when
you are talking with them. And as a basic rule, the more emotionally-laden the
topic, the more useful it is for a male and a female to sit or stand
side-by-side, rather than directly across from each other. Talking while doing
something active, such as taking a walk or washing the dishes or weeding a
garden patch can also be helpful, because the mutual activity functions as a de-stressor.
Part 4 tomorrow.

Gender Brain Differences, 2
Females
tend to connect with others through a conversation about emotions and feelings
even before they actually become involved in an activity (e.g., how their day
went, problems that cropped up, their feelings). Males tend to connect with
others through jokes and teasing and find it easier to discuss facts (e.g., the
weather, the stock market, the latest vehicle recall, and what happened with
the latest vehicle or plane crash). They find it more difficult to verbalize
emotions and feelings. What’s the take away? Know that your female friends will
likely be comfortable talking about how they “feel” about something that has
happened to them or that is going on in the world at the moment. Your male
friends, on the other hand, likely will not and are more likely to be more
comfortable talking about things, and data, and sharing jokes or teasing.
Remember, females, most males rarely spend the time and energy teasing someone
they really don’t like or sharing jokes with them. So if they tell you a joke
or tease you (appropriately, of course), recognize they are trying to connect
with you. Part 3 tomorrow.

Brain Gender Differences
Did you know that Connectome studies have identified
more than 100 “connection differences” between male and female brains?
Misunderstood, these differences often lead to frustration, miscommunication,
and even conflict. For example, males often want to “do” relationships
rather than “talk them out.” Two males can spend the day doing an activity
together (e.g., biking, hiking, fishing) and say little, if anything, to each
other verbally. And when they get home, both perceive they had a great day. Females
on the other hand, connect through conversation and just “doing” an activity
without any conversation seems somehow less satisfying. What’s the take away?
If females are with other females, there will likely be a lot of verbal
conversation. When males are with other males, there will likely be very little
verbal conversation. When a male and a female are doing something together, the
male needs to converse more than he would if with another male, while the
female needs to not expect as much conversation as she would have with another
female. Part 2 tomorrow.
