So how do we learn?
And why does some of us learn things more easily than others?
So, as I just mentioned, I'm Dr. Lara Boyd.
I am a brain researcher here at the University of British Columbia.
These are the questions that fascinate me.
(Cheers) (Applause)
So brain research is one of the great frontiers
in the understanding of human physiology,
and also in the consideration of what makes us who we are.
It's an amazing time to be a brain researcher,
and I would argue to you
that I have the most interesting job in the world.
What we know about the brain is changing at a breathtaking pace.
And much of what we thought we knew and understood about the brain
turns out to be not true or incomplete.
Some of these misconceptions are more obvious than others.
For example, we used to think
that after childhood the brain did not, really could not change.
And it turns out that nothing could be farther from the truth.
Another misconception about the brain
is that you only use parts of it at any given time
and it's silent when you do nothing.
Well, this is also untrue.
It turns out that even when you're at a rest
and thinking of nothing, your brain is highly active.
So it's been advances in technology, such as MRI,
that's allowed us to make these and many other important discoveries.
And perhaps the most exciting,
the most interesting and transformative of these discoveries
is that, every time you learn a new fact or skill,
you change your brain.
It's something we call neuroplasticity.
So as little as 25 years ago, we thought that after about puberty,
the only changes that took place in the brain were negative:
the loss of brain cells with aging,
the result of damage, like a stroke.
And then, studies began to show remarkable amounts
of reorganization in the adult brain.
And the ensuing research has shown us
that all of our behaviors change our brain.
That these changes are not limited by age,
it's a good news right?
And in fact, they are taking place all the time.
And very importantly,
brain reorganization helps to support recovery
after you damage your brain.
The key to each of these changes is neuroplasticity.
So what does it look like?
So your brain can change in three very basic ways
to support learning.
