BCI & NEUROTECHNOLOGY SPRING SCHOOL 2025
April 28 – May 7, 2025 (Vienna time)
The BCI & Neurotechnology Spring School 2025 was more than an event — it became a global phenomenon, with 90,816 participants from 140 countries, 140 keynotes over 140 hours, 95 hackathon teams with 727 hackers from 80 nations, and over 550,000 views in 10 days — all made possible by extraordinary people who gave their time and talent.
140 HOURS, 14 CREDITS, 1 GLOBAL EVENT
It’s quite amusing that we’re orchestrating the world’s largest neurotech event from Schiedlberg, a place where rabbits outnumber humans. Participants will access 140 hours of cutting-edge education, earning 14 credits and an exam certificate at no cost—an invaluable alternative to the typical $50,000 USD expense at prestigious universities. The potential value of our event, calculated at 82,881 attendees multiplied by $50,000 USD, amounts to a staggering $4,144,050,000 USD. We’re thrilled to offer this opportunity to individuals worldwide, free of charge.
