Blue Brain Portal

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

Models

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).

Online Tools

The online tools available to assist users with simulation neuroscience are a collection of platforms and atlases from the Blue Brain and our collaborators.

Online Learning

Simulation Neuroscience is an emerging approach to integrate the knowledge dispersed throughout the field of neuroscience.

Software

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.

Data

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 and the Human Brain Project Brain Simulation platform.

Publications

Blue Brain has published over 150 peer-reviewed scientific papers in international journals.

Enabling next generation brain simulations with performance modelling

— For the first time, scientists at the EPFL Blue Brain Project, a Swiss brain research initiative, have extended performance modelling techniques to the field of computational brain science resulting in findings that are useful for today and indispensable for the future. In a paper published in Neuroinformatics, they provide a quantitative appraisal of the performance landscape of brain tissue simulations, and analyze in detail the relationship between an in silico experiment, the underlying neuron and connectivity model, the simulation algorithm and the hardware platform being used. Thereby deriving the first analytical performance models of detailed brain tissue simulations, which is a concrete step to enable the next generation of brain tissue simulations.

Neuron_Reduce – a brand new tool to simplify complex neuron models

— Detailed neuron models consisting of thousands of synapses are key for understanding the computational properties of single neurons and large neuronal networks, and for interpreting experimental results. Simulations of these models are however, computationally expensive (using lots of computing hours), which considerably decreases their utility. For the first time, Scientists at the Hebrew University of Jerusalem and the EPFL Blue Brain Project have formulated a unique analytical approach to the challenge of reducing the complexity of neuron models while retaining their key input/output functions and their computational capabilities. ‘Neuron_Reduce’ is a new computational tool that provides the scientific community with a straightforward capability to simplify complex neuron models of any cell type and still faithfully preserve its input-output properties while significantly reducing simulation run-time.
