November – The First Digital Reconstruction of the Neuro-Glia-Vascular Architecture
 
Blue Brain has created the first digital reconstruction of the Neuro-Glia-Vascular (NGV) Architecture providing a new framework to study brain function in health and disease.

The study, published in Cerebral Cortex, represents a major milestone for the EPFL Blue Brain Project because they can now reconstruct the architecture of non-neuronal entities such as blood vessels and the supporting cells called glia. This means it is possible to capture the way that neurons, glia and the blood supply interact. These reconstructions of the brain tissue provide a sub-micron precise framework needed to simulate the molecular interactions relevant to understanding how neurons are supported and nurtured. They can also be used to investigate how drugs interact and explore how neurodegenerative diseases arise. Blue Brain has made all the experimental data, models and tools used to reconstruct brain tissue at this resolution, open source in the Blue Brain NGV web portal.

October – A Molecular Atlas for the Brain
 

Blue Brain open sources a simulation-ready database to accelerate molecular and systems biology.

Blue Brain scientists performed an extensive meta-analysis to integrate protein and metabolite quantitative data from publicly available resources and created this simulation-ready database to support more standardized and comparable molecular and systems biology studies.


July – Blue Brain Study – A machine reveals how glucose helps the SARS-CoV-2 virus
 
Why do some people get sick and die from COVID-19 while others seem to be completely unaffected?
EPFL’s Blue Brain Project deployed its powerful brain simulation technology and expertise in cellular and molecular biology to try and answer this question. A group in the Blue Brain assembled an AI tool that could read hundreds of thousands of scientific papers, extract the knowledge and assemble the answer – A machine-generated view of the role of Blood Glucose Levels in the severity of COVID-19 was published today by Frontiers in Public Health.

January – COVID-19 Crisis – A technology providing unconventional supply relief
 
When the full-scale effect of the COVID-19 pandemic was starting to be understood in early 2020,the EPFL Blue Brain Project and ETH Zurich, as part of the Swiss National COVID-19 Science Task Force, began collaborating with Spiez Laboratory on an online Platform – Academic Resources for COVID-19 (ARC). In a paper published in Frontiers for Public Health, the authors explain how the ARC Platform was set up to be a service to support Swiss diagnostic laboratories that are testing for SARS-CoV-2. The ARC Platform matched requests for critical equipment, reagents and consumable goods required by Swiss diagnostic laboratories involved in combating COVID-19 with supplies available from Swiss academic groups. Since then, with further input from Swiss startup Apptitude SA, the Platform has evolved with the needs of the epidemiological situation and the technology has been open sourced with the purpose to serve public health as a response solution for other countries and communities in the current COVID-19 crisis or in future crises.

2020

October – A step closer to mapping the rodent brain
 
The rodent Hippocampal formation is one of the most exhaustively studied regions in the mammalian brain but until now, there has not been a comprehensive knowledge base of its synaptic physiology. In a front cover paper published in the journal Hippocampus, researchers at EPFL’s Blue Brain Project present a data-driven approach to integrate the current knowledge on the hippocampal CA1 region using an open-access, comprehensive resource.

July – 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. 

July – 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.

May – 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.

February – 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.

January – 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.

August – 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.

August – 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.

August – 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.

July – Blue Brain builds the first next-generation models of thalamocortical neurons
 
In July 2019, Blue Brain announces it has built the first next-generation models of thalamocortical neurons. These digital models of thalamocortical neurons were built using state-of-the art optimization techniques, which directly constrain unknown parameter values with experimental data.

March – 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.

2018

November – 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.

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.

June – 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.
To date the paper has been viewed over 300,000 times.
 

Two more important papers were also published in June. In a paper published in Cerebral Cortex , we investigated the role of morphological diversity within and across neuronal types on emergent connectivity in a model of neocortical microcircuitry. Our investigation found that the average overlap between the dendritic and axonal arbors of different types of neurons determines neuron-type specific patterns of distance-dependent connectivity, severely constraining the space of possible connectomes.

DOI: 10.1093/cercor/bhx150


In the second paper published in Nature Neuroscience, the group of Idan Segev of the Hebrew University of Jerusalem in collaboration with the Cells & Circuits team in the Simulation Neuroscience Division of the Blue Brain, and Tel Aviv University identified a rich cell-type-specific network topology in neocortical microcircuitry. The systematic approach presented in the paper has enabled interpretation of microconnectomics ‘big data’, and provided several experimentally testable predictions.

October – Algorithm to predict connectivity in neural microcircuits

Blue Brain published a paper describing a mathematical algorithm that predicts the location of nearly 40 million synapses formed between the neurons in a small block of brain tissue about 100’000 times larger than has ever been analyzed with electron microscopy.
The algorithm uses millions of times less experimental data than would normally be needed using purely experimental methods. The algorithm was developed as part of the Blue Brain Project’s mission to digitally reconstruct the biological detail of the mouse brain and is a companion paper to the team’s paper on the Reconstruction and Simulation of Neocortical Microcircuitry.

DOI: 10.3389/fncom.2015.00120


October – Major Milestone achieved – Digital reconstruction of neocortical microcircuitry
 

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.
