Have you ever wondered when you are seeing?

When I was little I thought that
you do the same things or things

I have good news I have a bad
news I have good news
the good news is that yes they are beings
human beings
The bad news is they have superpowers
but the good news is that we too
can learn without superpowers
this super powers is called the method
scientific and method of engineering are the
two more powerful tools than the
humanity has created people to try
explain the world that we have our
turn around and transform it first using
science and technology
so I went there with about 15 years
when I joined the federal institute
that was when I discovered that there is
a research area called interfaces
brain machine and with this area of
search you can control things

Yes, it was invented by
Brazilian neuroscientist or teacher

series of techniques of how we can

I saw that there was a very

we send this electrical activity in the

Ok, he breaks his arm, that’s all.
because the method that we have today
doing this conversion works by having to
listen to the entire sentence first
Look I want, I want to close my hand.
only after translating the robot with the

I discovered that there is an article
published demonstrating that you if you

that you transform electrical activity

The problem is that those who have already

to be done
Luckily I ended up discovering that
there were two video game controls that

this completely changed the game in that
Now I knew I had to do it.
Anything about that, then I
I discovered that there was a time for partying

of psychology, which is called the

if a third arm is inserted a person
that had only two was not difficult
then reinsert an arm a person who

I proposed then people would create a version

it was possible to create a simulation

like this because my great-grandmother before
exp.
about that there would be something if you do
could use the same method as the
people use today for rehabilitation
master brain signals have these three
muscle signals send the computer
to do with the computer
learn it one way for the
communication research was launched in
2016 and 2006 and showed that 20% of
persons classified as vegetative

are misclassified

you can then know whether or not it is
she can not move
she can not move her eyes
you have an idea using the same
technology that is used to
rehabilitation, we can
to capture the brain signals that person
if they are still there send signals
for a computer and do with
that the computer understands that the person
it means and translate it is made of
very simple way because our
brain works electron contests and if
you put on a person’s head a
that has electrodes that have antennas
that capture this electrical activity
Can you tell a teacher if you
have me listening, I want you
imagine that you are moving your hand
right
If you say yes and if you
I’m listening, I want you.
imagine that you are moving a
left if you want to respond
not the computer will learn how it is
characteristic sign of the intention to
move your right hand as is the sign
characteristic of the intention to
movement of the left hand and with that
can you establish a degree of
communication through thought without
intervention of a muscle
and it was this kind of setup that I got
so I sponsor necessary to
build the program is capable of
identify these intentions of movement
of these people
initially classified as
vegetative diseases and you can see
here an effect test and a volunteer
healthy once the test with the
people really test
now ethical approvals
I know that a volunteer using a
cap with electrodes
the computer has already been trained as
prosthesis to understand what is the
movement of the right hand, which is the
movement of the left hand and translate
these two movements in yes and
no
The computer asks him a question.
to test a knowledge question
to certify if it really is
reasoning and he will answer only
with the thought that the audio help
people can ask the computer to ask me
if the italian capital of brazil
he will obviously imagine the hand
the computer detects this
intention of movement and translates into
brain activity an answer
he is having the left hand stimulated
So
response is recorded as not with this
we were able to create a tool
laptop that fits inside a suitcase
for technical terms trained to make
this kind of verification of conscience
brain activity in all
the capitals of Brazil in a way that
the whole family could request
this service and you had a solution
to the bedside to both with this
same technique
Do you have equipment that can
translate brain waves into action
in the case of persons in coma
vegetative responses but of the case by
example of people who have
paralyzed upper limbs
paralyzed for example in motion
just add all this scheme 11

robotics capable of opening and closing the hand
of a person in an artificial and
you have a portable carrying case for

thinking controlled
here a person like the member is doing
this type of intention and is being a member
artificially moved with everything
This I hope and when I
news about the research began to
be published actually reached the
people you needed in the comments
who received the most impact on my
that reminded me the most about my
situation with my great grandmother
That’s when my mother was in a coma.
I stood beside her waiting for some
sign her motionless and paralyzed
also just touched his hand waiting between
tears she would react
until today I wonder if it would have helped
speak something
if she would have involved me that day
not a word can get out of my
mouth
our goodbye with him silent in the name
of all the families that have passed through
This is now on behalf of my great-grandmother I
I can say
Bisa I’m here I ‘m not going
to make this happen to nobody else
thank you so much
