We found out that what determines which side has dominance happens before we're even born.

我們發現在人們出生之前就已經決定是由哪一側的大腦主導。

In the womb, when our spines develop, the way they wire up to our developing brains determines which side is dominant.

當我們的脊椎在子宮裡發育時，他們連接到正在發育的大腦，就已經決定哪一側為主導。

Why do we have a dominant side?

為什麼我們要有主導的一側呢？

Lateralization.

功能側化。

This refers to some brain functions taking place in one hemisphere or one side, rather than the other.

這是指某些大腦功能只發生在一側，而不是另一側。

Each hemisphere controls a different body side as well.

每個半球也控制不同側的身體。

Your dominant brain side connects to your dominant body side.

主導你的大腦那一側也會連接到身體那一側。

The left side of the brain controls the right side of the body.

左腦控制右半側的身體。

And the right side, the left.

右腦控制左半側的身體。

This cross-wiring of neural pathway means, if you are left-handed you are more relying on the right side of the brain.

這種交叉布線的神經通路代表如果你是左撇子，你就是較依賴用右腦思考。

And again vice versa.

相反地，如果你是右撇子，你就較傾向用左腦思考。

How does this affect our thinking style?

這會如何影響我們的思維呢？

The left side and the right are responsible for very distinct thinking patterns.

左腦和右腦負責非常不同的思維方式。

Generally, the right brain thinks in pictures instead of words.

一般來說，右腦是以圖像思考，而不是文字。

Using intuition and focusing on the bigger picture.

運用直覺和專注於更大的前景。

The left focuses on actual words.

Thinking in a very verbal way.

以非常口頭的方式思考。

Honing in to details first, and then putting them together to form a whole picture.

先聚焦細節，然後把它們拼湊形成整體圖像來思考。

It's widely agreed upon that the right side is creative and the left is logical.

這就是為什麼我們認同右腦是創新的，左腦是合乎邏輯的。

How is language affected?

那語言是如何受到影響呢？

The left side is good for vocabulary, grammar, and literal meanings.

左腦擅長背詞彙、文法和字面意思。

The right side is great for intonation and accentuation, basically, how we speak.

右腦擅長語調和重音，基本上就是我們如何說話。

How is music heard in the brain?

如何在大腦中聽到音樂呢？

We already know the right side is more creative.

我們已經知道右腦較具創造力。

Music processing takes place in the entire brain.

音樂在整個大腦中環繞。

With the right side focusing on the melody, while the left side focuses on the motor scale your hands need to play the instrument.

右腦專注在旋律，左腦則專注於運動音階，讓你的手可以彈奏樂器。

Is it true that math is left-brain business?

數學真的是左腦的專長？

We assume the left side, being more logical, does more math.

我們假設左腦較有邏輯性，可以處理更多數學運算。

Things such as counting, adding, subtracting, etc.

像是加減乘除運算等等。

The right, however, actually helps with estimating amount of sets of objects.

然而，實際上右腦有助於我們估算物件。

While your left brain might help you take a test, the right brain can tell you how many boxes are still on the delivery pallet at work.

雖然左腦可以幫你考試，但右腦可以告訴你工作托盤上還有多少盒子。

Which side handles the memories?

那哪一側處理記憶呢？

The hippocampus is actually the part of the brain associated with memory.

實際上，海馬體是與記憶有關的大腦部分。

And it occupies both sides of the brain.

它佔據了大腦兩側。

The left side has been deemed more important for storing memories, as its strength is in retrieval.

因為左腦的優勢在於檢索，所以被認為是儲存記憶較重要的一側。

The right side is good for reciting, like multiplication tables.

而右腦較擅長背誦，像是九九乘法表。

Which side will help me more in wilderness survival camp?

哪一側會幫助我在野外求生營中生存下來？

Depending on our situation, the sides we depend on change.

根據我們不同的情況，所需要的兩側會有變化。

Studies have shown that in warm places with more calm moods and less risks to your life, the right side is better.

研究發現在溫暖的環境下，情緒更加平靜，生命危險較小，右腦側會比較好。

The left kicks in when it's cold.

在寒冷的時候，左腦側開始起作用。

The food is scarce, and threats to your life like unyielding polar bears are abundant.

食物短缺，加上許多不屈不撓的北極熊威脅著你的性命。

Survival skills are based more on spatial awareness and logic.

生存技能更多依賴空間警覺性和邏輯性。

Not creativity.

而不是創造力。

So the left side controls more of our ability to survive.

所以左腦掌控更多我們的生存能力。

How does damage to the right side affect a person?

右腦受傷會對人們造成什麼影響？

Damage to the right side could lead to self harm and even suicide.

右側受傷可能導致自殘甚至自殺。

An overactive right side can cause feelings of depression and angst.

It can also cause problems with language and perception, such as the lack of emotion while speaking.

還可能造成語言和感知的問題。像是說話時缺少情緒。

How does damage to the left side affect a person?

左腦受傷會對人們造成什麼影響？

Left-side damage affects vision.

左腦受損會影響視力。

There is a reduction in spatial frequency,

空間頻率降低了。

so we only see the larger parts of an image.

所以我們只能看到圖像較大的部分。

Speech also seems to be littered with grammatical errors.

說話也似乎充滿語法錯誤。

This is called Broca's aphasia.

需要強調的是，並沒有正確或是錯誤的思維方式。

兩側各有優勢，代表著兩種不同的思維方式。

If you want to increase your brain power, work on both sides of your noggin.
