NEURON 7.6.2 is now available for download.

New features since NEURON 7.5 include:

  • Simplified installation
    • Accepting the default install options now allows running from command line and GUI in Mac and Windows.
  • Enhanced Jupyter notebook support
    • NEURON error messages now display inside the notebook
    • Experimental notebook ShapePlot available through neuron.gui2
  • GUI improvements and bug fixes
    • Sections created in Python are now selectable using the NEURON GUI's "Plot What" functionality
    • MovieRun now works when NEURON is run via Python
    • Per-segment colorization of Shape objects via shape.color(colorindex, seg)
  • Extracellular reaction-diffusion support (described in Newton et al., 2018)
    • Available through the neuron.crxd module which also supports intracellular reaction-diffusion with just-in-time compiled reactions
  • Miscellaneous enhancements and bug fixes
    • NEURON methods now return appropriate data types (int/bool/float), e.g. pc.nhost() now returns an int
    • Enhanced comparison support for NEURON objects
    • New section methods for morphologies, e.g. sec.pt3dadd()
    • New sec.psection() methods provides a data structure describing that section's properties
    • NetCon.preloc() and NetCon.preseg() now return true NetCon locations
    • Import3D now ignores blank lines in SWC files

Multiscale modeling with NEURON tutorial at CNS 2018

The tutorial will present recent advances in methodologies for simulating the electrophysiology of cells and networks in the context of lower and higher scales or organization. At the lower scale, we will describe the simulation of intracellular chemical signals including calcium in subcellular compartments (dendrites and spines), with application to understanding of synaptic plasticity and the response of neuronal dynamics to modulators. At higher scales, we consider the brain as an organ, situating neurons in a complex environment of modulators, ions, and metabolism. The NEURON simulator will be used to illustrate the interactions among these levels, using NEURON's rxd reaction-diffusion module for intracellular and extracellular chemophysiology, and NetPyNE ( for managing parameters and for building complex networks of detailed cells as brain structures. We will also introduce new graphical methods (GUIs) for managing these extremely complex simulations. For more information see

2018 NEURON Summer course

The 2018 NEURON Summer Course will be held at Emory University in Atlanta, Georgia, from Monday, August 6, through Saturday, August 11.

The course will present a thorough introduction to computational modeling of neurons and networks with NEURON, and is suitable for individuals at all levels of expertise.  This year continues the 6 day curriculum we introduced last year in order to provide expanded coverage of parallel simulation, and to give participants more time for active learning exercises.

The registration deadline is Monday, July 16, 2018.  No applications will be accepted after that date, and there will be no on-site registration.  Space is limited, and applications will be considered in the order received.

Registration deadline for 2017 SFN courses approaching

Friday, Oct. 27 is the registration deadline for the one day course on NEURON 
and the half day workshop on the Neuroscience Gateway
Space is still available at these events, but if you want to sign up, you'll have to act quickly.

Programmer's Reference: Python documentation and hoc documentation

More and more NEURON users are employing Python to build models, so we're making it easier to jump right to NEURON's Python documentation. Click on the "Programmer's Reference" link in the list of resources on the Documentation page, or at the top of any of this site's pages, and you'll see the front page of the Python documentation. If you need the hoc documentation, just click on the "Switch to HOC documentation" link near the top of that page.

Three upcoming courses!

From 9 AM to 6 PM on Thursday, July 20, 2017--just next week!--Robert McDougal and others will be speaking at an OCNS meeting workshop on Reaction diffusion modeling in Antwerp, Belgium. Learn the latest about NEURON's RxD (reaction diffusion) module, as well as approaches to reaction diffusion used by other advanced simulation tools such as MCell, MOOSE, and NeuroRD.

We are also announcing two satellite sessions to the 2017 Society for Neuroscience meeting: a 1 day course on NEURON that will be held from 9 AM to 5 PM on Friday, Nov. 10, and a half day workshop from 9 AM to noon on Saturday, Nov. 11, on how to use the Neuroscience Gateway Portal for computationally intensive modeling and data analysis tasks.

For more information about these events, including registration instructions, see NEURON's Courses page

NEURON at the CNS 2017 meeting

From 9 AM to 6 PM on Thursday, July 20, 2017, a workshop on Reaction diffusion modeling for neurobiology will be held in connection with the CNS 2017 meeting in Antwerp, Belgium. Among the many speakers will be Bill Lytton and Robert McDougal, who will probably have something to say about NEURON's RxD (reaction diffusion) module. This workshop will be a great opportunity to learn the latest about the approaches used by advanced simulation tools such as MCell, MOOSE, NEURON, NeuroRD and others to deal with models that involve reaction diffusion, and the kinds of scientific questions that are being studied with these tools. For more information, including schedule, speakers, and how to register, see

Courses and workshops at the 2016 SFN meeting

The 2016 meeting of the Society for Neuroscience will include two satellite sessions that are highly relevant to modelers.

  • a one day NEURON course from 9 AM to 5 PM on Friday, Nov. 11
  • a workshop on the Neuroscience Gateway Portal from 9 AM to noon on Saturday, Nov. 12. The NSG is an NSF-supported resource that offers modelers free CPU time and a convenient user interface for running parallel simulations or performing other computationally intensive tasks on high performance hardware.

The registration deadline for both of these events is Friday, Oct. 28, Friday, Oct. 2, is the registration deadline for both of these events, but space is limited so you should sign up early. See for more information and links to registration forms.

Two important events at the 2015 SFN meeting

Two events of particular interest to modelers will be presented as satellite sessions to the 2015 SFN meeting in Chicago:

  • practical introduction to NEURON on Friday, Oct. 16 from 9 AM to 5 PM.
  • workshop on the Neuroscience Gateway Portal on Saturday, Oct. 17 from 9 AM to Noon. The NSG makes it easy for modelers to run parallel simulations on high performance hardware by eliminating most technical and administrative barriers (it even gives away free CPU time).

Friday, Oct. 2, is the registration deadline for both of these events, but you should sign up early because space is limited. See courses for more information and links to registration forms.

Arrangements for NEURON course at the 2015 SFN meeting

With the 2015 NEURON Summer Course ready to start just a bit more than a week from now, we're already getting ready for the course that we will be presenting in Chicago at the 2015 SFN meeting in November. The official announcement will go out shortly before registration opens for the SFN meeting.
