Your Eyes, Your Ears, Your Brain–Oh my!!

By: Tina C. Davidson

Brain_ears_eyes_communicationThe unearthing of previously unknown information about how our brain/body functions fascinates me.

So, I was pretty intrigued when I saw the following article title in The Atlantic by Ed Yong:

When Your Eyes Move, So Do Your Eardrums

… and no one knows why.

Well, eventually someone will try to figure out the “why,” but until then at least we know that when your eyes move, so do your eardrums. Right?

They also found that the eardrums start to wobble about 10 milliseconds before the eyes. This suggest that the ears aren’t reacting to what’s happening in the eyes. Instead, Groh says, “the brain is saying: I am about to move the eyes; ears, get ready.”

That is some pretty fast communication between the brain and the ears (0.01 seconds–wowzers–that’s like spidey-sense).

For a closer look at this study, you can check out, “The eardrums move when the eyes move: A multisensory effect on the mechanics of hearing.” (Here’s the link Proceedings of the National Academy of Sciences of the United State of America.)

I’ll leave you with this quote from The Atlantic to ponder.

“This suggests that there are no safe spaces in the brain,” Groh says. “One sensory system is influenced by another right at the point where the physical energy is first detected.”

Don’t let it keep you up at night–that part about there being “no safe places in the brain.”

We can’t always comprehend how the brain functions, but we know that the brain is pretty amazing.

Obviously, I’m a fan.

Back to School and Your Brain

By: Tina Davidson

First_Day_of_School_Thumbs_down

It’s that time of year again. Social media is filled with pictures of kids sporting new shoes and holding chalkboards to document their current grade level.

The first day of school should be a happy day for students, right?

Rarely do you see a sobbing child in a back-to-school photo (I know I cried when I started kindergarten) or belligerent photos of kids flipping off the camera  (a little league softball team learned the repercussions of this the hard way).

Although not all kids appreciate having their picture taken, they all love going back to school, right?

A thumbs down picture might be as far as some moms will let their kids go in expressing their disdain for having to go back to school.

The topic of kids being able to express themselves was addressed in a book I (sorta) read during summer vacation.

The first time I busted out the book, “How Children Fail,” by John Holt, my youngest son was appalled.

“It’s just mean to write a book about how children fail.”

B. Davidson, age 8

I tried to explain that it was a book about helping kids and preventing failure.

To my dismay, I failed to finish reading it, but I did succeed in reading the book’s summary.

One section of the summary that resonated with me was a discussion the author had with teachers.  Holt felt that most teachers aren’t honest about their feelings of impartiality (liking some students more than others).  This creates feelings of guilt in teachers and some force fake smiles around their students.

He went on to mention that the children in these classrooms end up resenting their phony teachers and this in turn creates phony kids. **You’ll have to read the passage to get all the context.**

“As we are not honest with them, so we won’t let children be honest with us. To begin with, we require them to take part in the fiction that school is a wonderful place and that they love every minute of it. They learn early that not to like school or the teacher is verboten, not to be said, not even to be thought. ”

“How Children Fail” by John Holt, Pg. 284

Have you ever corrected your child for complaining about school?

Guilty here.

I don’t want to encourage Eeyores (poor dear!) when it comes to school, but every kid should be free to express themselves.

Here’s a scary passage from the summary:

“It is a rare child who, anywhere in his growing up, meets even one older person with whom he can talk openly about what most interests him, concerns him, worries him.”

YIKES!!

Looking back, I’m glad my son expressed his dislike to me about my choice in summer reading books.

Holt also has a book titled, “How Children Learn.” I should probably let my son see me reading that one too. Or at least ask him how he feels about learning.

How do you feel about all this? Need some tools to help communicate with your child or help them with school?

The passion for stretching yourself and sticking to it, even (or especially) when it’s not going well, is the hallmark of the growth mindset. This is the mindset that allows people to thrive during some of the most challenging times in their lives.

Check out the book, “Mindset,” by Stanford University psychologist, Carol Dweck. I read all of this fascinating book and I’m continuing to work on my mindset.

People with a growth mindset are also constantly monitoring what’s going on, but their internal monologue is not about judging themselves and others in this way. Certainly they’re sensitive to positive and negative information, but they’re attuned to its implications for learning and constructive action: What can I learn from this? How can I improve?

Whether we are “in school” or not there is always more to learn.

Have a great school year!

Your Brain’s Playlist

By: Tina Davidson

Tina_Davidson_tinadavidson_wordpress

This is me with “Tina” in Germany circa 2000.  Photo Credit: One of my college roommates. 

Music evokes strong emotions and can bring back memories long forgotten.

When I hear the song, “Cotton Eye Joe,” by Rednex, I am transported back to college and I picture myself surrounded by friends dancing under a black light.

I never really thought of my current playlist (Cotton Eye Joe, you didn’t make the cut) as a scientific tool, but now that’s changed.

Read All About It

My mindset has changed thanks to the book, “Your Playlist Can Change Your Life.” It boasts, “10 Proven Ways Your Favorite Music Can Revolutionize Your Health, Memory, Organization, Alertness, and More.”

Now that’s some big claims. I haven’t finished the book yet, but I’m listening to a lot of music and paying better attention to it.

Parental Advisory:  Stick to the songs that bring back good vibes.

Brain Tunes

Chapter 10, “How to Use Your Brain’s Own Music,” intrigued me the most. Music can be made from your brain’s own waves and added to your playlist.

Bonus Track:  Google “Brain Music Therapy” (BMT) and “Galina Mindlin“– once you’ve discovered BMT, there might be a cure for your insomnia after all.

Pump up the Volume

Here’s a few songs from my Summer Playlist:

I may regret my choices later (but all scientists have a work in progress, right?)

  • “Shake Shake Shake (Shake Your Booty)”- KC & the Sunshine Band

  • “Help”- The Beatles

  • “I Wanna Be a Lifeguard”- Blotto

  • “Last Night a DJ Saved my Life”- Indeep

  • “Obviously 5 Believers”- Old Crow Medicine Show

  • “Can’t Stop the Feeling”- The Piano Guys

Where’s the Show?

There’s nothing quite like hearing your playlist songs performed live. I doubt I’ll hear any of my summer playlist songs at the Cal Poly Performing Arts Center any time soon, but looks like the 2017-2018 season is going to be a good one.

Do you have a favorite local performing arts center? Here’s my top picks of the upcoming Cal Poly Arts shows (wish I could afford to attend them all):

  • Bill Murray, Jan Vogler & Friends- Oct 8

  • Steep Canyon Rangers- Jan 21

  • Improvised Shakespeare- March 16

  • Black Violin- Feb 17

  • Itzhak Perlman- Jan 16

  • Michael Feinstein- Jan 26

  • Andrew Bird- Oct 16

  • Koresh Dance Company- April 14

  • Cameron Carpenter- Feb 26

  • Brasil Guitar Duo- Oct 14

I Heard you on the Wireless

Special thanks to Cal Poly DJ, “Jack Funk,” for pouring out the groovy tunes on Wednesday evenings on KCPR (congrats on your graduation). My boys enjoyed listening to your show during our twenty-minute commute to gymnastics.

They’ll never forget that:

“Last night a DJ saved my life with a song.” Lyrics by Indeep

 

Happy listening! Here’s to a happy and healthy brain.

Please share your summer playlist in the comments.

Have you read, “Peak–Secrets from the New Science of Expertise”?

artist-mom

By: Tina Davidson

Did you ever dream of becoming great at something? Maybe it was singing or playing piano?

Well, with enough deliberate practice you might just make your dreams come true.

I’ve been reading,”Peak–Secrets from the New Science of Expertise,” by Anders Ericsson and Robert Pool. I recommend you pick up a copy. It is fascinating stuff and I won’t give away too much. Let’s just say I was especially impressed with the memorization skills of London taxi drivers.  I was also quite intrigued with Laszlo Polgar’s experiment–his goal was to raise three genius children. It seems he succeeded.

Here’s my favorite quote from Peak (pg. 179):

“Deliberate practice can open the door to a world of possibilities that you may have been convinced were out of reach. Open that door.”

I hope I’ve shared enough to “peak” your interest about the book.

Let me know what you think!
