ModelDB and NSCI 550

We're teaching a course in neuroinformatics at Yale, and one of the assignments is for students to find a published model in ModelDB, read the associated paper, download and use the source code, and then give a brief presentation.

NEURON-related research at the SFN 2010 meeting

We've been trying to build a list of presentations at this year's SFN meeting that report work done with NEURON, and so far we have found 42 talks and poster sessions--see

Typos: one of many reasons why model sharing is essential

A few days ago we received an email from a NEURON user who was working through the examples in
Hines, M.L. and Carnevale, N.T.

NEURON + Python hands-on tutorial

On Saturday morning, Nov. 13, 2010--just before the Society for Neuroscience meeting--there will be a four hour course on NEURON + Python. Continental breakfast will be provided. Registration is free, but space is limited, so if you are interested you should sign up quickly. For further information see the full announcement on The NEURON Forum

NEURON 2010 Summer Course now open for registration

The NEURON 2010 Summer Course is now open for registration. This intensive hands-on course will be held June 19-23 at the Institute for Neural Computation on the campus of the University of California, San Diego. Registration is limited, and the application deadline is Tuesday, June 1, 2010. For more information and the on-line registration form, see

Online resources

Here's a list of some of my favorite online resources related to computational modeling. NEURON's WWW site

Preparing for the winter 2010 meeting and course

Preparations for the winter (barely!) meeting and course at the U of A in Tucson, AZ (March 22-26, 2010), continue to move along. All this happened on December 1: announcements went out, new WWW pages were launched (see, and registration opened. Several people have already signed up, most from outside the vicinity of Tucson.

Announcement of Meeting and Course in March 2010

We're announcing two events for late March 2010 -- "The 2010 NEURON Simulator Meeting" and "Course on Parallelizing Network Models with NEURON". These will be held at the University of Arizona in Tucson, AZ, during the week of March 22, 2010. Registration is limited (30 for the Meeting, 10 for the Course), and the registration deadline for both events is Friday, Feb. 26, 2010. For more information and an on-line registration form, see

NEURON 7.1 now available

The new standard distribution of NEURON is version 7.1, which is available from the download page A few new features have been added, such as
  • A Python Section can be given a name and/or and owner when it is constructed. For example, in a Cell class the constructor can make sections as in
    soma = h.Section(self, name = 'soma')

IntFire4 improvements: thanks to van Elburg and van Ooyen!

The algorithms used in the IntFire4 artificial spiking neuron have been revised to be more biologically plausible, in light of findings described in a paper by Ronald van Elburg and Arjen van Ooyen which appeared in a recent issue of Neural Computation (see REFERENCE below). We would like to take this occasion to describe their results and thank them for making this valued contribution to the community of NEURON users.

IntFire4 is a "current-based" integrate and fire mechanism which has an "excitatory current" that decays with time constant taue, and a biphasic "inhibitory
