in so many different directions at a time,
зэрэг сатаарч байдаг учир
if you can stay focused.
is all about what we are focusing on,
анхаарал гэж боддог ч
our brain is trying to filter out.
мэдээллийн тухай ойлголт юм.
you direct your attention.
you move your eyes towards something
you pay attention to something,
your direction of the eyes,
the surrounding area,
brain-machine interfaces,
технологи хоёрын уялдааг судалж
the brain and the computer.
we can build models for the computers,
how well our brain functions.
компьютер тодорхойлдог.

төхөөрөмж болох юм.

an interesting model for computers.
сайн загвар болгож байгаа юм.
what are the brainwave patterns
or when you look covertly.
ямар байгааг мэдэхийг хүссэн.
there are two flickering squares,
2 дөрвөлжинг ашигласан.
at a slower rate than the other one.
you are paying attention to,
анхаарлаа хандуулснаас хамааран
will start resonating in the same rate
ижил давтамжтай болж өөрчлөгдөнө.
you are watching
when you pay overt attention,
тархинд юу болдгийг мэдэхийн тулд
in one of the squares
we saw that these flickering squares
анивчих дөрвөлжингүүд
from the back of their head,
of your visual information.
хэсгээс гарч байсан.
when you pay covert attention.
бид мэдэхийг хүсэж байлаа.
to look in the middle of the screen
дунд хэсэг рүү
to either of these squares.
анхаарахгүй байхыг хүссэн.

it seems that it works as a filter
only from the right flicker
дүрснээс ирэх дохиог хүлээн авч,
coming from the ignored one.
авахгүй байхыг хичээдэг.

but there was no way to respond,
хариу өгөх ямар ч аргагүй байлаа.
because he was illiterate.
тайлагдаагүй байсан юм.
нас барсан билээ.

Why you should listen
Mehdi Ordikhani-Seyedlar is a research scientist interested in brain-wave patterns generated by neural activities in the brain. Since embarking on his research on neuroscience, Ordikhani-Seyedlar has been working on different brain functions such as learning, memory, pain and, more recently, visual attention in humans. He also conducted a part of his research on monkeys when he was in Dr. Miguel Nicolelis' lab at Duke University. His findings help implement more accurate brain-machine interfaces to treat people who are suffering from attention deficiency.
After receiving his Ph.D in Biomedical Engineering, Ordikhani-Seyedlar was offered a postdoctoral position by Duke University to develop algorithms to process large-scale neuronal activity and brain-machine interfaces. However, due to political complications in the United States, Ordikhani-Seyedlar -- an Iranian citizen -- changed his plan to continue his brain research outside the US for some time.
As a passionate neuroscientist and neuroengineer, Ordikhani-Seyedlar's aim is to improve brain pattern detectability in computers. This enhances the ability of brain-machine interfaces substantially to better target the defected brain function which in turn enhances the sustainability of treatment effect.
