0:05
So there I was, happy, having a blast,
0:09
the queen of the night, and Dora.
0:12
Then, as a next decision, I called
0:15
my ex, not once, but 27 times. You don't
0:20
call your ex 27 times. And then, since he didn't answer, I
0:24
sent him an audio message: "
0:30
Hi, I'm a physicist. This is Brain Without
0:36
Today we're going to talk about
0:39
decision-making. Have you noticed that
0:40
we make thousands of decisions all the
0:42
time, from choosing lunch today to
0:44
school and not having blue hair anymore, to
0:46
more difficult things. Here I am, in grades with my
0:48
boyfriend, deciding what I'm going to study. Searching on the
0:51
internet, I found Pablo,
0:53
a scientist who is an expert on the brain and
0:55
decision-making, and I
0:57
emailed him and he said I could have
0:59
an interview. So now I'm going to
1:04
Thank you very much for having me, Boyacá. Welcome, thank you
1:06
very much. Today I should ask
1:07
what happens in the brain when one makes
1:09
decisions. We know that many
1:12
areas of the brain are active at the moment
1:13
we are making a decision. A very
1:15
important area is the prefrontal cortex, the
1:17
area that is right behind the forehead.
1:18
Your well-being is important because...
1:20
Our behavior is controlled by our brains. We make
1:22
decisions that make us feel good.
1:23
All decisions that give us
1:25
pleasure activate a series of
1:28
brain areas called the
1:29
reward circuit, which is directed by
1:35
information from one place to another. This is where we
1:36
make a decision or do something
1:38
that gives us pleasure, even just the pleasure of
1:40
eating something delicious,
1:42
like a piece of meat, really tasty, with a
1:44
high floor, of course. Except when you eat
1:46
something you like, dopamine is released, and
1:48
that generates pleasure. And what
1:50
exactly happens when one makes a decision?
1:51
As we are making decisions, we
1:54
also integrate many factors,
1:55
internal factors of our own, like
1:58
how we feel, the thoughts we
1:59
have about ourselves, and
2:01
also many external things, like the influence of
2:03
a family member, a friend, or
2:04
loved ones. These are also
2:06
very important, as is the knowledge we
2:08
have about things. For example,
2:10
if they were on the corner, we know that the
2:11
red light indicates that we shouldn't cross. They get angry, run over,
2:15
Radio 07. We are making decisions
2:16
from the morning of the spectator, we
2:19
turn it off and decide that we get up
2:20
25 minutes later, or more
2:22
transcendental decisions like... For example, sometimes we're going to
2:24
marry someone. In fact, my
2:26
first day is getting married, so I've already decided
2:28
who else to marry. There's a restriction
2:31
if you want to note it down. Later, going to the
2:33
lab, I can see how your brain works
2:54
inside a magnetic resonance imaging (MRI) machine. You can't really see what an MRI machine is, but well, today the SDK at the German clinic and it seems like the MRI machine... so, I hope I'm lucky. Very well, finally we're in person. With this machine, you take pictures inside
2:57
digital pictures that I had also run
2:58
inside. The reasoning goes through a
3:00
game, or game, you know, it's like using a
3:02
club, and meanwhile I can take
3:03
images of your brain. So, we're going to
3:05
see in the brain how every time
3:06
you make a decision...
3:32
artistically, your brain in the image we just
3:35
took is occasionally...
3:36
well, all this area is your
3:38
prefrontal cortex. Perhaps it's very important for
3:42
the perfect connection, the action over
3:43
time. While we have more time,
3:46
this better channel can integrate
3:47
more things. Decision-making... what happens
3:49
in adolescence is that the
3:51
prefrontal cortex is maturing, so it's not
3:54
learning... To value certain
3:56
options and certain decisions, it might not be the
3:58
weekend, it could be with your friends, having a
4:00
good time and suddenly
4:01
putting aside going to study,
4:06
and it happens to all of us to some extent, for
4:08
example, a bill that is known to have a
4:10
great influence on social acceptance, you
4:12
see parents giving when they are not in
4:15
the career, it was a certain feeling, it is
4:17
known that it was a liberation from Europe, it is
4:20
pleasant for us not to be
4:21
socially accepted and that can be
4:23
good because it generates many
4:25
relevant social behaviors for cooperation,
4:27
solidarity, but also this other
4:29
side that can make us make
4:31
riskier decisions or not, let's
4:33
put more effort into it so that the rest laugh,
4:35
but it is important to give your
4:38
prefrontal cortex time to integrate all the
4:41
long-term consequences to make various decisions,
4:43
there was a social reward in three
4:45
hours, I have to be ready for
4:46
marriage, victims, so, so I have to, hey
4:48
Pablo, thank you very much for so
4:52
much information like this, thank you for
4:54
coming and I hope you do very well in
4:56
marriage, impressive the number of
4:58
sessions you don't take and all the things
5:00
that influence and all the work the
5:02
brain does, the important thing is that one decides
5:04
which to take on, a responsibility at the same
5:07
time, I For my part, I am going to
5:08
pass it on here at the wedding. My cousin
5:09
Domingo shouted the studio I have
5:12
now, I'm going to fix it. I do
5:15
n't see myself loving Mediaset. I'm
5:19
leaving now, so I hope you liked
5:20
the chapter a lot. See you next
