This year the NEURON Summer Course will be held at the HHMI|Janelia Research Campus in Ashburn, Virginia. Only a few seats remain open, so you'll have to act quickly if you are interested in taking "NEURON Fundamentals" or "Parallel Simulation with NEURON." The NEURON Fundamentals component, which runs from June 20-24, is suitable for individuals at all levels of expertise. It presents a thorough introduction to computational modeling of neurons and networks of neurons with NEURON, and introduces parallel simulation. Parallel Simulation with NEURON runs from June 25-27 and focuses on the needs of experienced NEURON users who want to create models that will run on parallel hardware. Knowledge of how to write hoc or Python code for NEURON is presumed. You may apply for one or both components, but registration is subject to approval by the course's faculty. Space is limited, and applications are considered in the order received. The application deadline is Friday, May 20, 2016. No applications will be accepted after that date, and there will be no on-site registration.
