क्या हम मस्तिष्क को फिर से बना सकते हैं? | शॉन सिमोनिनी | TEDxBoston Salon

न्यूरोडीजेनरेटिव बीमारियाँ, मस्तिष्क की चोटें, स्ट्रोक और उम्र से जुड़ी गिरावट को लंबे समय तक स्थायी माना गया, क्योंकि मस्तिष्क में नए न्यूरॉन बनाने की क्षमता सीमित है। TEDxBoston Salon की इस वार्ता में Sequel Neuroscience के सह-संस्थापक और CEO शॉन सिमोनिनी बताते हैं कि मस्तिष्क में नए न्यूरॉन प्रत्यारोपित करके इस क्षति के कुछ हिस्से को उलटा जा सकता है। वे पार्किंसन रोग के शुरुआती परीक्षणों से लेकर वर्तमान शोध तक की कोशिका प्रतिस्थापन थेरेपी का विवरण देते हैं।

• मस्तिष्क की क्षति को लंबे समय तक अपरिवर्तनीय क्यों माना गया
• पार्किंसन के शुरुआती परीक्षणों से वर्तमान शोध तक कोशिका प्रतिस्थापन थेरेपी
• केवल बचे हुए ऊतक को सुरक्षित रखने के बजाय खोए हुए ऊतक को बहाल करना

NOTE FROM TED: Research discussed in this talk remains an ongoing field of study. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf When neurons die, our brains have little capacity to make new ones. This has meant that neurodegenerative conditions, traumatic brain injuries, strokes, and age-related decline have all been considered permanent and irreversible. Sean Simonini learned this the hard way, but sees hope in our ability to reverse this damage by transplanting new neurons into the brain. He traces how cell replacement therapies, from early trials in Parkinson’s to cutting edge science, are beginning to break the long-held belief that damage to the brain could never be undone. He argues that neurology is shifting from preserving what is left, to restoring what was lost, and asks what this means when new cells become a part of us. Sean Simonini is a Co-Founder & CEO of Sequel Neuroscience which is working on regenerative therapies for stroke, ALS, and other brain conditions. Previously, he was a researcher at the University of California, San Francisco and Harvard University, studying stem cell biology and neurodevelopment. He also led several nonprofits to grow the Boston biotech ecosystem, support public education, and address food insecurity. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
