Blue Brain Portal

Welcome to the Blue Brain Portal from the EPFL Blue Brain Project – a knowledge space for simulation neuroscience


Multi-scale models of the rat and mouse brain integrate models of ion channels, single cells, microcircuits, brain regions, and brain systems at different levels of granularity (molecular models, morphologically detailed cellular models, and abstracted point neuron models).

The Real Neuron Challenge

Built by Blue Brain’s Neuroscientific Software Engineering team, this challenge enables everyone from scientists, to STEM students, to visualize reconstructed and synthesized neurons and decide if they can spot the differences between them. This game shows that it is hard to distinguish which cells are digitally generated and it demonstrates that synthesized neurons are similar to biological in terms of morphological properties.


Data is of vital importance to the study of the Brain. For neuroscientists in this section, there are ion channel recordings, morphological reconstructions, electrical recordings from neocorticol neurons and molecular properties of neurons. These are available on Blue Brain platforms, the EBRAINS Cellular Level Simulation Platform and the Hippocampus Hub.


Blue Brain has published 237 papers and pre-prints in scientific journals.

Software Suites

Blue Brain’s reconstruction and related simulations are made possible by a comprehensive software ecosystem for each step in the reconstruction and simulation process. Blue Brain systematically releases open source software.
