Download and Install NEURON

One of these choices will be right for you.

The current standard distribution: Recommended for the vast majority of users, especially anyone who is starting a new project. It's the latest version that is "stable" in two senses: everything seemed to be working properly at the time of release, and no new features will be added to it (although bug fixes will be provided).
A prior version: For users with legacy code. Not for starting new projects, since no new features or bug fixes will be provided.
"Alpha" version installers and development code: For those who need to stay up-to-date with the latest changes in NEURON, or who are contributing new tools and features. Relatively few users will need this.

The current standard distribution (version 7.0)

Precompiled installers

For greatest convenience, get one of the precompiled installers. If your operating system is not listed below, or if you need to customize the installation (e.g. change the location of binaries or the number of layers used by extracellular), you should instead get the source code for the standard distribution and compile it on your own machine.

Mac OS X 10.4

Double click on it.
Drag the NEURON-n.n folder to where you want it (or even leave it in the virtual folder).

Select the appropriate package for your system:

Double-click the deb package on the desktop, or in a terminal as root type
dpkg -i filename
