The early registration discounts for this year's NEURON summer courses were originally supposed to end today, but we have been able to arrange to continue the discounts for as long as seats remain open, or until the Friday May 30 registration deadline. NEURON Fundamentals June 21-24 This addresses all aspects of using NEURON to model individual neurons, and also introduces parallel simulation and the fundamentals of modeling networks. Includes a healthy serving of Python. Parallel Simulation with NEURON June 25-26 This is for users who are already familiar with NEURON and need to create models that will run on parallel hardware. Special attention will be paid to critical topics such as powerful strategies and idioms for implementing and managing models, measuring and improving performance, and debugging. $1050 for the Fundamentals course $650 for the Parallel Simulation course $1600 for both These fees cover handout materials plus food and housing on the campus of UC San Diego.
