BRIAN simulator

We are happy to report that our paper “Brian 2, an intuitive and efficient neural simulator” has been accepted for publication in eLife: https://elifesciences.org/articles/47314 In this paper, we describe a number of examples that showcase various ... [More] features of Brian 2, ranging from non-standard neuronal/synaptic models to interacting with hardware in real time via C++ [...] [Less]

We are happy to announce the release of Brian 2.2. This release includes a number of important fixes and performance improvements. It also makes sure that simulation no longer give platform-dependent results for certain corner cases that involve the division of integers. For a full list of changes, see the release notes. We recommend all [...]

We are happy to announce the release of Brian 2.1.3. This release includes a number of important fixes and performance improvements. For a full list of changes, see the release notes. We recommend all users of Brian 2 to update. From this release on, conda packages will be provided via the conda-forge channel. For a [...]

We’ve released Brian 1.4.4, a maintenance release for Brian 1 that fixes compatibility issues with recent versions of numpy/sympy. The packages are available on PyPI: https://pypi.python.org/pypi/brian Note that for new projects, you should use Brian 2 instead, the Brian version under active development.

We have released new bug fix releases for Brian 2 (version 2.1.2) and Brian2GeNN (version 1.1.5). The new Brian 2 release fixes two bugs: an incorrect application of the substitution mechanism in equations (i.e. when using the same set of equations several times and changing the equations’ variable names via Brian’s Equation class), and an [...]

We are happy to announce the release of Brian 2.1. This release includes a number of fixes and small improvements, and two new major features: support for numerical integration with adaptive-timestep methods based on the GNU Scientific Library, and ... [More] caching of code generation leading to faster simulation setup times, in particular for multiple runs of [...] [Less]

We are proud to announce the release of Brian2GeNN, the Brian 2 interface to the GPU-enhanced Neuronal Network (GeNN) simulator. With this interface, a Brian 2 script (as long as it only uses supported features) can benefit from the potential performance benefits of a GPU by adding just two lines to the start of the [...]

We are happy to announce the release of Brian 2.0.2. This release includes a large number of fixes and improvements, in particular important updates for the unit system and multi-compartmental simulations. Note that with this release we provide conda packages for Python 3.6, but no longer for Python 3.4. For an extensive list of changes, [...]

We are happy to announce the release of Brian 2.0.1. This is a bug fix release which does not add any new features but fixes a few important bugs and updates the documentation. Earlier versions of Brian 2 contained bugs that could lead to incorrect recordings from subgroups with PopulationRateMonitor and SpikeMonitor. The issue was [...]

We are very pleased to announce the release of version 2.0 of the Brian neural network simulator. Brian is a free, open source simulator for spiking neural networks. It is written in the Python programming language and is available on almost all platforms. We believe that a simulator should not only save the time of [...]
