我们来想一下讨论这些问题的不同方法s!@F*xcy2Z8

If someone is left-wing……they are considered to have liberal views.

如果某人是左翼......他们被认为有自由主义观点wpQMfwbB1Nzld

And if they are right-wing.

xbrmA*1r_fe

如果他们是右翼的话MrWoF67oL+

If they are right-wing they are thought to be more conservative.

Scientists carried out MRI scans on two British Members of Parliament–MPs - as well as 90 other students and postgraduates.

q17=tjRaIUd

科学家们对两名英国国会议员以及其他90名学生和研究生进行了核磁共振扫描u[_WNhiSnGkhi

LhtuAO&!ppKc;

Their hypothesis–the theory they are testing to see if it is correct or not - is to find out if there is any difference in their brains.

eM[TZhU&c46#eNEr[7Jk

他们的假设——他们正在测试这个理论是否正确——是为了找出扫描者的大脑是否有任何不同J=A.|pYO!TTu7XL_4|#=

.(n!dNspKqEdgd

These MRI scans can measure the thickness of the grey matter in the brain–that’s the outer layer of the brain which varies in thickness, and is full of neurons–nerve cells, which are very sensitive.

y*YK]%u6y(xo=|Iw|xUX

这些核磁共振扫描可以测量大脑灰质的厚度——灰质是大脑的外层,它的厚度变化不定,充满了神经元——神经细胞,它们非常敏感wc]6AxpSQnhLYgI4=

It’s time to get down to the serious business of scanning our MPs–one left and one right-wing to see if we can find any differences in the structure of their brains.

G4YQEsNsqM

是时候认真地扫描议员的大脑了——一个左派和一个右派,看看我们是否能在他们的大脑结构中发现任何差异^P&gWJ@ONYy

We’re going to look in detail at the thickness of the grey matter - that’s the outer covering of the brain.

&jW-M|S-BNoK

我们将详细观察灰质的厚度——灰质是大脑的外层覆盖物t)Gj2jz^M+&H

.vCG|*R~nc5rq%NVx^

The hypothesis we’re testing is to see whether there is any significant difference in the shape or structure - the thickness of the grey matter covering the brain - between people who self-classify as either left or right wing.

RHBjEad=XCGIB_2

我们正在测试的假设是,看看在自认为属于左翼或右翼的人之间,大脑的形状或结构(覆盖大脑的灰质厚度)是否存在显著差异61vjRB4aXId

()POc@TE0D8%]+rIA#@-

So did people who self-classify themselves–describe themselves as being liberal or conservative - have different shaped brains?

=[Ryxf)qg*e6D#imCWv|

那么,那些把自己归类为自由派或保守派的人是否有不同的大脑形态呢?

g(XIxerf0lb1_Jx9zY

What the scientists found was that people who have thicker grey matter in one area of the brain–the anterior cingulate- described themselves as being liberal or left-wing, and those with a thinner layer described themselves as conservative or right-wing.

n_v~WN4eqzbbP

科学家们发现,大脑前扣带灰质较厚的人将自己描述为自由派或左翼,而那些灰质较薄的人将自己描述为保守派或右翼T#Li,!L*n^)HlU0eHQ

杰伦特·里斯教授说:

#;lvZ,W&.=n~[tK1Z%mo

We find there are two areas of the brain–one called the anterior cingulate and the other called the amygdala, whose structure seems to vary according to their self-described political attitudes.

HVWfdkz#JxNHT.mSV

我们发现大脑中有两个区域,一个叫做前扣带,另一个叫做杏仁核,其结构似乎根据他们自我描述的政治态度而变化NQU&nb)y)yLR8

RQwyG~,HG##

The anterior cingulate is a part of the brain that’s on the middle surface of the brain, at the front.

CqGfFTz-D,s7F36@U!

前扣带是大脑的一部分,在大脑的中间表面,在前面iqs1]goX7^,~-c

sxn~-5ZCKIlu2M]g8KQ

And we found that the thickness of the grey matter–where the nerve cells or neurons are - was thicker the more people described themselves as liberal or left-wing, and was thinner the more people described themselves as conservative or right wing.

5Pvaaxg+8;

我们发现,大脑灰质(神经细胞或神经元所在的地方)的厚度在认为自己是自由派或左翼的情况下越厚,认为自己是保守派或右翼的情况下越薄LB]hbYFnO-c3F

Av9gqc=@XE49FQ.WXK

That’s all very interesting, Alice–but what about people who change their political beliefs as they get older?

~O;cZ9J=2R+&8

这些都很有趣,爱丽丝——但是那些随着年龄增长而改变政治信仰的人呢?

=nP9jx^XB-i8+

Does this mean their brain shapes change too?

^DnM9kY*sn#u=Xh33cqR

这是否意味着他们的大脑形状也会改变呢?

K66nH.GO+BAx

We don’t know yet if brain shape changes as people’s political views change.

4F,!tr6cW1)+4]6uJp

我们还不知道大脑形状是否会随着人们政治观点的改变而改变a[3Aj4szs6Fd5m9hLT

More research needs to be done - but scientist Professor Colin Blakemore from Oxford University says that grey matter can change shape in the brain.

9N)bE-G5kATQS^2wMrL#

虽然还需要做更多的研究,但牛津大学的科学家科林·布莱克莫尔教授表示,灰质可以改变大脑的形状D]#ix8&rj(&5.X8z|

F5ly7^SeJP

For example, even playing computer games for a short period of time a week can change the shape of your grey matter:

cEyRz-VUvvq4g

举个例子,甚至在短时间内玩电脑游戏,比如一个星期,你的灰质形状都会改变:

z@T2LWGQ;=X#N

We know from lots of other recent studies, that the brain - even the grey matter of the brain, the part that’s being measured in these studies - can change its organisation incredibly rapidly, simply teaching someone computer games for a few minutes each week, can cause their grey matter in certain areas of the brain to change thickness.

tjeFXMcdH(*_ke=AGvi

从很多最近其他的研究中我们了解到大脑,甚至大脑灰质,被测量的部分在这些研究中,其组织可以迅速改变,每周简单教一些人玩几分钟电脑游戏,也会导致他们的大脑灰质在某些区域改变厚度@vC*]Q_eY0~

w%++B](eUC64

So perhaps even people who seem hard-wired to believe certain things may be able to change their minds and the shape of their brains too.

jJz&WMuLAm^OilbNE

因此,即使是那些似乎天生相信某些事情的人,他们的思想和大脑的形状也可能改变!jpLBWSo4_c[|c
