00:14

So how do we learn?

00:16

And why does some of us learn things more easily than others?

00:21

So, as I just mentioned, I'm Dr. Lara Boyd.

00:24

I am a brain researcher here at the University of British Columbia.

00:28

These are the questions that fascinate me.

00:31

(Cheers) (Applause)

00:35

So brain research is one of the great frontiers

00:38

in the understanding of human physiology,

00:41

and also in the consideration of what makes us who we are.

00:45

It's an amazing time to be a brain researcher,

00:47

and I would argue to you

00:49

that I have the most interesting job in the world.

00:52

What we know about the brain is changing at a breathtaking pace.

00:56

And much of what we thought we knew and understood about the brain

00:59

turns out to be not true or incomplete.

01:03

Some of these misconceptions are more obvious than others.

01:06

For example, we used to think

01:09

that after childhood the brain did not, really could not change.

01:14

And it turns out that nothing could be farther from the truth.

01:18

Another misconception about the brain

01:19

is that you only use parts of it at any given time

01:23

and it's silent when you do nothing.

01:25

Well, this is also untrue.

01:27

It turns out that even when you're at a rest

01:29

and thinking of nothing, your brain is highly active.

01:33

So it's been advances in technology, such as MRI,

01:37

that's allowed us to make these and many other important discoveries.

01:40

And perhaps the most exciting,

01:42

the most interesting and transformative of these discoveries

01:45

is that, every time you learn a new fact or skill,

01:49

you change your brain.

01:51

It's something we call neuroplasticity.

01:54

So as little as 25 years ago, we thought that after about puberty,

01:58

the only changes that took place in the brain were negative:

02:01

the loss of brain cells with aging,

02:03

the result of damage, like a stroke.

02:06

And then, studies began to show remarkable amounts

02:09

of reorganization in the adult brain.

02:13

And the ensuing research has shown us

02:15

that all of our behaviors change our brain.

02:19

That these changes are not limited by age,

02:23

it's a good news right?

02:24

And in fact, they are taking place all the time.

02:27

And very importantly,

02:29

brain reorganization helps to support recovery

02:32

after you damage your brain.

02:34

The key to each of these changes is neuroplasticity.

02:39

So what does it look like?

02:41

So your brain can change in three very basic ways

02:44

to support learning.
