Benefits of a bilingual brain

How about mastering multiple-languages? Like Reading in original books?

The mastering of three languages is better, meaning you can easily read and write, in addition to understanding the spoken slang?

Just thinking we understand the spoken language does Not cut it. We have got to read the original authors and works.

Researchers now know that learning another language is actually an amazing way to keep your brain healthy.

Believe it or not, before the 1960s, researchers thought children learning other languages was a handicap.

People back in the day, reaction times on some language tests. made some hypotheses that must mean it’s a drawback for students to know more than their original language (biased tests?.

It won’t necessarily make you smarter, but Mia Nacamulli points out it’s now believed that being bilingual “exercises your brain and makes it stronger, more complex, and healthier.”

And if you’re young, you get an added bonus

What does being bilingual really achieve?

1. It changes the structure of your brain.

Researchers have observed being multilingual can visibly make the neurons and synapses in the brain’s gray matter denser and spur more activity in other regions of the brain when using another language.

Basically, it’s a brain workout!

And another neurological study notes the white matter in the brains of older lifelong bilinguals has a higher integrity compared to older monolinguals. (What integrity means in this context?)

2. It strengthens your brain’s abilities.

That gray matter up there contains all the neuronal cell bodies and stuff (that’s a technical term) that controls your muscles, senses, memory, and speech.

Newer studies show that those slow reaction times and errors on language tests really reflect that the effort of switching between languages is beefing up the dorsolateral prefrontal cortex — the part of your noggin’ that controls problem-solving, switching tasks, and focusing on important stuff while filtering out what’s irrelevant.

3. It can help delay Alzheimer and dementia disorders by as much as four or five years.

Yes. Sí. Oui. When bilinguals are compared to monolinguals, that is.

And although some cognitive research notes there’s still a similar rate of decline after onset, more years of a super-strong brain is always a good thing.

Now, this fourth one gets a little bit nuts.

Nacamulli says it’s believed there’s a key difference between a young bilingual person and someone who learns another language in adulthood.

4. There’s a theory that children who are bilingual get to be emotionally bilingual.

The parts of the brain that are being strengthened while speaking multiple languages include not just the analytical and logical side of the brain but the emotional and social side as well.

It’s called the critical period hypothesis.

The separation of the hemispheres increases as we grow up, and so when you’re a kid — the hypothesis holds — the two sides are a little more plastic and ready to work together while learning language.

Nacamulli says this could be why children seem to get the contextual social and emotional nuances of other languages better than grown-ups who became multilingual later and instead often think  like grown-ups.

Speaking more than one language turns our brains into powerhouses, and it makes our children more emotionally intelligent!

It’s definitely not a handicap. It’s a superpower.

For more on the magical bilingual brain, TED-Ed has some great info!

Note: Though I’m trilingual (speaks, reads and write), my verbal intelligence (rhetoric and clear vocalization of intentions) is pretty deficient. Verbal intelligence is a matter of nurturing while a kid (to be spoken to, asked your opinions, invited to mingle with grown up people, initiated to artistic courses…)

Any objective measurable Sciences behind Yoga and Stress?

There are two functional parts of the brain that play a key role in stress.

These serve the functions of emotion and cognitive function.

So I am calling them the ’emotional’ brain (amygdala and its connections and medial forebrain structures including the medial prefrontal cortex) and the ‘logical’ brain (the dorsolateral prefrontal cortex, other parts of the prefrontal cortex, parts of the cingulate cortex and parts of the hippocampus)

(Humm. Now that names have been attached the science can proceeds)

How to get rid of stress

This is what bending your body into yoga poses does to your brain chemistry and nerve connections.

The emotional brain is able to initiate a ‘stress response’ via the sympathetic nervous system which culminates in adrenaline and cortisol racing through our circulation.

The logical brain is always trying to ‘turn-off’ this stress response and it is also trying to restrain the emotional brain.

The stronger our logical brain, the better it becomes at doing these two things.

When the stress response is ‘turned off’, our parasympathetic nervous system signal is ‘turned on’. This signal ‘relaxes’ the body. So a strong logical brain goes hand in hand with relaxation.

The stress response and ‘relaxing’ signals travel through the body along a particular route and parts of this route have little ‘switches’ which we can physically manipulate to turn the signals on or off.

The neck is an example of where such switches are located (by the carotid arteries).

Everytime we are holding a posture our logical brain is being activated
“Everytime we are holding a posture our logical brain is being activated”

Training the stress circuit

Yoga is training this entire stress circuit at two levels.

First, every time we are ‘holding’ a posture, staying very still to concentrate or trying to balance, our logical brain is being activated.

When we are bending forwards, our ‘relaxation’ signal is being turned on through the ‘switches’ in the neck. So bending forwards and concentrating at the same time is triggering both the logical brain and the relaxation signal at the same time.

Bending backwards triggers the stress response signal through the switches in our neck. Contracting a muscle also triggers the stress response signal.

So, when we bend backwards and contract our muscles while still having to stay still and concentrate on balancing, our logical brain is given an extra challenge.

It has to overcome the stress response signal being triggered in these two ways before we can be still and concentrate during a posture.

This ‘extra’ resistance the logical brain is having to work against, ‘trains’ it like a muscle.

Rewiring the nerve connections

At the end of a series of yoga postures, the logical brain has had a ‘workout’. It is buzzing with activity.

You feel mentally calm as it is keeping your emotional brain quiet. Training the logical brain in this way for a long time can result in a rewiring of the nerve connections within the logical brain.

New circuitry that enables you to find it easier to control your thoughts is formed. You may find it easier to channel your thoughts in the direction you want and not ‘dwell’ on negative thoughts or experiences.

This is partly why yoga seems to have a positive effect on depression and anxiety, where sufferers have a tendency to dwell on negative life events. Stronger connections within the logical brain keeps the lid down on the emotional brain and the stress response.

This is why yoga can be so effective at battling stress.

The key thing to do is to attempt yoga postures which are structured in a well-formulated sequence where each posture involves a long hold.

Then your yoga and stress will begin to be balanced.
