Blue Brain co-develops COVID-19 Diagnostic Implementation Simulator
 
With the EPFL Blue Brain Project’s determination to make our computing resources and expertise available for the fight against COVID-19, we brought our experience in software development to team up with the Foundation for Innovative New Diagnostics (FIND). FIND is a global non-profit organization focused on diagnostics, currently co-convening the Access to COVID-19 Tools (ACT) Accelerator Diagnostics Partnership alongside The Global Fund, as a key part of the global response to the pandemic. According to the World Health Organization (WHO), diagnostic testing for COVID-19 is critical to tracking SARS-CoV-2 (the virus responsible for COVID-19), understanding epidemiology, informing case management, and suppressing transmission. With diagnostics emerging as one of the most pressing issues in the COVID-19 crisis, Blue Brain has collaborated with FIND to develop a Diagnostic Implementation Simulator for SARS-CoV-2 diagnostics. 

Blue Brain Nexus Forge: Building and using Knowledge Graphs made easy
 
A deluge in digital data, the trend for cross-disciplinary and multi-modal scientific investigations along with the tremendous computing power now available, has led to team based, data-driven and data-intensive methods commonly used in science. These advances also come with a set of challenges summarized in the FAIR (1) guiding principles for research data management – make heterogeneous data generated from different contexts, Findable, Accessible, Interoperable and Reusable. Accordingly, Knowledge Graphs have become the go-to key solution across both research and industry to address these challenges.

EPFL and ETH Zurich deliver Academic Resources platform for COVID-19
 
With Switzerland starting to transition out of lockdown, testing for SARS-CoV-2, being a cornerstone of all response strategies, is more important than ever in order to contain the risk of a renewed increase in cases as public life slowly picks up again. Ensuring an adequate number of daily tests for this task requires precise and timely distribution of equipment, supplies and other resources. To support this endeavor, the EPFL Blue Brain Project and ETH Zurich, as part of the National COVID-19 Science Task Force, are collaborating with Spiez Laboratory on an online platform, Academic Resources for COVID-19 (ARC), to match critical support needed by Switzerland’s diagnostic laboratories with the support offered by the Swiss academic sector.

Blue Brain enable next generation brain simulations with performance modelling
 
Scientists at the Blue Brain Project 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, we 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.
Blue Brain collaboration with the Hebrew University of Jerusalem.
 
For the first time, Scientists at the Hebrew University of Jerusalem and the 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.

Blue Brain finds the secret to how neurons in the mouse neocortex form billions of synaptic connections
 
Researchers at Blue Brain have combined two high profile, large-scale datasets to produce something completely new – a first draft model of the rules guiding neuron-to-neuron connectivity of a whole mouse neocortex. Based on these rules, we were able to generate statistical instances of the micro-connectome of 10 million neurons, a model spanning five orders of magnitude and containing 88 billion synaptic connections that will serve as the basis of the world’s largest-scale simulations of detailed neural circuits.

Brain finds order amidst chaos
 
How does the brain find order amidst a sea of noise and chaos? Blue Brain found the answer to this long-standing question by using advanced simulation techniques to investigate the way neurons talk to each other while submerged in a sea of noise and chaos. In a paper published in Nature Communications, we found that by working as a team, cortical neurons can respond even to weak input against the backdrop of noise and chaos, allowing the brain to find order.

Blue Brain ion channel study beckons first whole-brain simulation
 
The Blue Brain Project’s ‘Channelpedia’ is open to brain modellers and pharmacologists everywhere. Pores at the surface of neurons and muscle cells control your every thought, movement; the very beating of your heart. The way the pores behave – that is open, close, or lock for a short time (inactivate) depending on voltage – shapes signals in the form of electrical charge (ions) moving across the cell surface. For the first time, we have mapped the behavior of the largest family of these voltage-gated ion channels: Kv channels. Published in Frontiers in Cellular Neuroscience, with freely available online data.

Blue Brain solves a century-old neuroscience problem
 
In a front-cover paper published in Cerebral Cortex, Blue Brain explains how the shapes of neurons can be classified using mathematical methods from the field of algebraic topology. Neuroscientists can now start building a formal catalogue for all the types of cells in the brain. Onto this catalogue of cells, they can systematically map the function and role in disease of each type of neuron in the brain.

The Blue Brain Portal
– a knowledge space for simulation neuroscience is launched as a public resource
 
Released in August, the Blue Brain Portal brings together in one place open-sourced software, tools, models and data, both from us and our collaborators. The aim is for this knowledge to be utilized by both the neuroscientific and the wider scientific community to develop the field of simulation neuroscience.

Blue Brain Project releases first-ever digital 3D brain cell atlas
 
Like “going from hand-drawn maps to Google Earth,” the Blue Brain Cell Atlas allows anyone to visualize every region in the mouse brain, cell-by-cell – and freely download data for new analyses and modelling.

The first digital 3D atlas of every cell in the mouse brain provides neuroscientists with previously unavailable information on major cell types, numbers and positions in all 737 brain regions – which will potentially accelerate progress in brain science massively.

Blue Brain Team Discovers a Multi-Dimensional Universe in Brain Networks
 
A team of scientists led by the Blue Brain Project used a sophisticated type of mathematics in a way that it has never been used before in neuroscience. The team uncovered a universe of multi-dimensional geometrical structures and spaces within the networks of the brain.

This research, published in Frontiers in Computational Neuroscience, has significant implications for our understanding of the brain.

Blue Brain Project launches three-day conference to kick-start neuromodulation research – NM2
 
The NM2 Conference was conceived to address understanding the mechanisms by which neuromodulators operate which is both fundamental to Blue Brain’s pioneering work in simulating brain function and dysfunction, and for the global neuroscience community

Leading experts from around the world presented and took part in panel discussions across the three days. Additionally, the NM2 Conference provided a unique platform for students and junior researchers to interact with leaders in the field to collectively take part in shaping the future course of neuromodulatory research.

2016

The Blue Brain Project releases the Blue Brain Python Optimization Library (BluePyOpt)an extensible open source framework for data-driven model parameter optimization that wraps and standardizes several existing open-source tools. The library includes methods for setting up small- and large-scale optimizations on a broad range of compute platforms – from laptops to large cloud-based compute infrastructures.

2015

Blue Brain reaches a major milestone with the publication of a first draft of the digital reconstruction of neocortical microcircuitry (Markram et al, 2015). The study confirmed the feasibility of building and simulating a digital copy of a part of the brain and demonstrated that multidisciplinary Big Science in the field of neuroscience yields favorable results (82 scientists contributed to the study).

The paper, which appeared in the journal Cell, represents the most complete description of any neural microcircuit to date. It provides a complete digital map of all the cells and synapses in a block of neural tissue and describes simulation experiments replicating a range of previous in vivo experiments. In other words, our digital copy of a part of the brain behaves like a real part of the brain.

Most significantly, this study advances the case for simulation as a useful new method in neuroscience. It proves that we understand the basic properties of the components and interconnections of the brain well enough to be able to reconstruct and simulate certain physiological functions. This advance makes it feasible, in principle, to reconstruct the human brain even though we can never measure all its parts.
