Here are some potentially helpful resources for NEURON users and others who employ computational modeling in neuroscience research and teaching.

ModelDB is a database of published computational neuroscience models.
Neurons in Action
written by John Moore and Ann Stuart (Sunderland MA 2007, Sinauer Associates), is a book and CD-ROM that present a set of interactive tutorials for teaching neurophysiology to students at all levels.
Source code for exercises
from Bill Lytton's book "From Computer to Brain" (New York 2002, Springer-Verlag).
by Arthur Houweling, a GUI-based NEURON tool for performing the computational experiments described in the book "Electrophysiology of the Neuron" by John Huguenard and David McCormick (New York 1994, Oxford University Press). We link to the curated version from ModelDB; an older version is available from but is not guaranteed to work with recent releases of NEURON.
