In recent years NEURON has been taught. Available from http://www.neuron.yale.edu

 

Grading Basis:  In a typical year, grading basis is 40% homework and problem sets, 20% midterm during week 6, 30% term project, and 10% group oral exam the last day of classes.

 

Sample syllabus:  Suggested readings are from BOG (Bower and Beeman, Book of Genesis  http://www.genesis-sim.org/GENESIS/iBoG/index.html), K (Koch, Biophysics of Computation) and NB (Carnevale and Hines, The NEURON Book).  Extensive lectures notes will be available on-line.  Lecture overheads will be distributed in class.  Topics covered up to the mid-term are fairly static.  Topics after the mid-term may vary depending on interests.
