The 2017 NEURON Summer Course will be held at Wright State University in Fairborn, Ohio, from Monday, June 5, through Saturday, June 10. The course will present a thorough introduction to computational modeling of neurons and networks with NEURON, and is suitable for individuals at all levels of expertise. This year we have increased the course duration to 6 days (5 days in previous years) in order to provide expanded coverage of parallel simulation, and to give participants more time for active learning exercises. The registration deadline is Monday, May 15, 2017. No applications will be accepted after that date, and there will be no on-site registration. Space is limited, and applications will be considered in the order received.
