in so many different directions at a time,
बहुत दिशाओं में जाता है
if you can stay focused.
तो यह बहुत बढ़िया है l
is all about what we are focusing on,
ध्यान केंद्रित करने के बारे में है
our brain is trying to filter out.
कि हमारा मस्तिष्क
you direct your attention.
अपना ध्यान निर्देशित करते हैं
you move your eyes towards something
एक वस्तु पर ले जाते हैं l
you pay attention to something,
आप एक वस्तु पर ध्यान देते हैं,
your direction of the eyes,
the surrounding area,
आपके क्षेत्र का क्रमवीक्षण कर रहा है,
काम करता हूं,
the brain and the computer.
हमारे लिए महत्वपूर्ण हैं
we can build models for the computers,
कंप्यूटर नमूना बनाते है,
how well our brain functions.
can be used as assistive devices
an interesting model for computers.
what are the brainwave patterns
or when you look covertly.
there are two flickering squares,
at a slower rate than the other one.
you are paying attention to,
will start resonating in the same rate
you are watching
when you pay overt attention,
दिमाग में क्या होता है?
in one of the squares
we saw that these flickering squares
हमने देखा कि ये झिलमिलाते वर्ग
from the back of their head,
of your visual information.
when you pay covert attention.
आपके दिमाग में क्या होता है?
to look in the middle of the screen
स्क्रीन के बीच में देखने कहा,
to either of these squares.

दिमाग के संकेत में दिखी,
which was paid attention to,
जिस पर ध्यान दिया गया था,
the activation of the frontal area.
ललाट क्षेत्र की सक्रियता
हिस्सा जिम्मेदार है
उच्च संज्ञानात्मक कार्यों के लिए l
it seems that it works as a filter
only from the right flicker
coming from the ignored one.

is indeed a key for attention,
ध्यान के लिए ज़रूरी है
cannot inhibit these distractors,
बाधित नहीं कर पाते,
for a long time on a single task.
ध्यान नही लगा पाते
संज्ञानात्मक मस्तिष्क-मशीन जुड़ाव का उपयोग

but there was no way to respond,
because he was illiterate.
जब मैं इस क्षेत्र में काम कर रहा हूं,
हम मस्तिषक-तरंग का प्रतिरूप पा सकें,
about images or even letters,
पत्रों के बारे में सोचते हैं,
a different brainwave pattern
communicate for people who can't speak?
the thoughts of a person in a coma?
समझने में मदद करेगा ?

ABOUT THE SPEAKERMehdi Ordikhani-Seyedlar - Neuroscientist

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.
