October – Unlocking the Secrets of Neuronal Function: A Universal Workflow
Detailed single neuron modeling has emerged as a powerful tool for exploring the intricacies of neuronal function. However, the diversity of neurons in the mammalian cortex, the outer layer of the brain responsible for higher cognitive functions, poses a significant challenge, as existing computational tools often focus on specific features of a single neuron type. In this new front cover paper published in Patterns, the EPFL Blue Brain Project introduces a groundbreaking new universal workflow that simplifies the creation, validation, and generalization of detailed neuronal models, offering researchers unprecedented insight into the world of neural science. Its usefulness and performance are demonstrated by the building of cell models for a significant portion of the rat cortex. The approach is built upon open-source tools, with all the steps freely available, and offers researchers a comprehensive solution for constructing neuronal models that can represent either a single biological cell or a predefined type of cells.
September – Empowering Neuroscientists: New Open Source Tools for Modeling
Concurrently with the release of a two-part preprint on the juvenile rat non-barrel Somatosensory Cortex (nbS1) covering both its anatomy and physiology as well as the release of the model itself, Blue Brain is sharing three complementary software packages. These were central in the simulation and analysis of the model which contains over 4 million structurally detailed neurons and more than 14 billion connections. Working with a model of that scale and level of detail is extremely complicated; Blue Brain therefore developed software tools for the simulation, validation, and analysis of the model.
ConnectomeUtilities is a powerful tool for researchers working with complex networks; it offers streamlined analysis and provides insights into network properties, especially in the context of biologically detailed models of neural circuits. BlueCelluLab is a versatile tool that allows scientists to conduct virtual experiments, helping them better understand the intricate behavior of brain cells. Meanwhile, Neurodamus enables the running of large-scale simulations on powerful computer clusters efficiently.
March – New Circuit Model Offers Insights into Brain Function
EPFL’s Blue Brain Project has developed a groundbreaking computational model of the thalamic microcircuit in the mouse brain, offering new insights into the role this region plays in brain function and dysfunction. The new model, published in Cell Reports, is the first to capture the complex shapes and biophysical properties of 14,000 neurons connected by 6 million synapses. It can be used to explore the structural and functional complexity of neural circuits. The model also replicates multiple independent network-level experimental findings across different brain states, and provides a novel unifying cellular and synaptic account of spontaneous and evoked activity in both wakefulness and sleep. The model is now accessible for researchers to use in their own studies via the Thalamoreticular Microcircuit Portal.
February – New release of Blue Brain Project Atlas sheds light on neuron types
After four years of research, EPFL’s Blue Brain Project shares an enriched version of their 3D digital cell atlas of the mouse brain which includes more neuron types. The new approach can be extended to any other cell type, and provides a resource to build tissue-level models of the mouse brain.
The new tools and methods used to refine the Cell Atlas and produce the BBCAv2, published in two companion papers in PLOS Computational Biology (Rodarie et al., Roussel et al.), were extended to map well identified types to inhibitory neuron subclasses, paving the way for more accurate in silico reconstructions of brain tissues. The data, algorithms, software, and results of the pipeline used to upgrade the Blue Brain Cell Atlas are all publicly available.
January – Blue Brain Nexus – brain scale data and knowledge management
Modern day science typically involves iterative cycles of data discovery, acquisition, preparation, analysis, model building and validation which often lead to knowledge discovery as well as knowledge sharing and dissemination. Given the ambitious goal of digitally building and simulating the mouse brain, the EPFL Blue Brain Project required a data and knowledge management system that could not only handle the enormous diversity and evolution of data at the scale of the whole brain, but also track the data’s provenance to ensure quality, reproducibility and accurate attribution throughout these iterative cycles. Accordingly, Blue Brain built and open sourced Blue Brain Nexus as a key technology for organizing brain tissue data and models and as a complementary approach to classical neuroinformatics tools. Blue Brain Nexus has now grown into an ecosystem of secured, domain-agnostic, scalable and interoperable tools with a growing community of adopters including large international organizations, across use cases that include neuroscience, psychiatry and open linked data.
October – STEPS 4.0 towards large-scale biologically-relevant simulations
Simulating neurons down to the level of their biochemistry in order to understand their behavior and properties is a complex computational challenge. While small to the human eye, a neuron is a comparatively large object relative to its biochemical constituents. Yet, the overall behavior of a neuron depends on the specific composition and interactions at the molecular level that will control its electrical properties. It’s like aiming to fully describe a patch of forest down to the millimeter, recording the location and shape not only of each tree and each leaf, but of each grain of dirt. Even with high performance computing and ever increasing computing power, scientists still have to make uncomfortable compromises; phenomena that are random in nature are averaged out for ease of calculation, or only parts of a cell can be described with molecules and their interactions. Needing to choose between what is biologically relevant and what is able to be addressed, leads to significant loss of information and, often, relevance. In a paper published in Frontiers in Neuroinformatics, the Blue Brain collaboration with he Okinawa Institute of Science and Technology Graduate University, Japan (OIST) introduces a new generation of the project – STEPS 4.0.The paper describes how they pushed the boundaries of simulating biochemical diffusion-reaction models to the scale of entire neurons. The new solution dramatically reduces the computer memory needed while maintaining similar or better performance, increasing overall scalability.
September – Neuron Phenotype Ontology – classifying the brain’s building blocks
As the study of neuroscience accelerates ever faster and our understanding of the intricate workings of the brain deepens, the need to define a standardized approach to naming neuron types has become imperative. As the building blocks of the brain, neurons are studied intensely with vast amounts of data being generated and shared. With this comes several challenges as there is more and more data to describe different cell types. Furthermore, the literature contains many neuron names that are commonly used and accepted, even when it is unclear how such common usage types relate to the many proposed evidence-based types that are based on the results of new techniques. In addition, there is the significant question of comparing different data sets across labs. This all points to an urgent need for a standardized approach to naming neurons and for the organization of knowledge about their properties. In a paper recently published in Neuroinformatics, a collaboration of Scientists from the Swiss EPFL Blue Brain Project, University of California, San Diego, University of Toronto, Canada and the Krembil Centre for Neuroinformatics, Canada, propose an interoperable knowledge representation – Neuron Phenotype Ontology (NPO). The NPO is an open source standardized and automatable approach for naming cell types and normalizing their constituent phenotypes using identifiers from community ontologies as a common language. It is designed to enable scientists to discover which cell types (or potential cell types) share similar properties and to help scientists understand when the cell types they observe are the same or similar to other cell types described in the literature or from other laboratories. Moreover, it provides a framework for systematically organizing knowledge about cellular properties and enables interoperability with existing neuron naming schemes.
July – A secret language of cells? New cell computations uncovered
Throughout evolution, individual cells have been making successful decisions on their own, even while forming parts of vast networks, such as neurons and glia in the human brain. Now scientists from the EPFL Blue Brain Project and King Abdullah University of Science and Technology (KAUST) have published a new theory in the Journal of Theoretical Biology describing a secret language that cells may use for internal dialog about the external world. Using a computational model, they hypothesize that metabolic pathways, which are primarily a means of extracting energy and building block molecules from glucose and other substrates to feed the brain, might also be capable of coding details about neuromodulators that stimulate increases in energy consumption. If true, this would open the door to a nearly infinite number of possibilities for information processing in nervous systems as component cells could compute in previously unexplored ways. Such a mechanism would also help explain the remarkable energy efficiency of brains.
July – Sustainable, portable and high performing – updated NEURON simulator
In recent years, simulation has firmly become the third pillar, alongside theory and experimentation, for studying the brain. The computational models of brain components, brain tissue or even whole brains provide new ways to integrate anatomical and physiological data and allow insights into causal mechanisms crossing scales and linking structure to function. Over the past four decades, the NEURON simulator has been developed and continuously extended to enable neuroscientists to model the electrical activity of neuronal networks. Today, it is one of the most widely used simulation environments for biologically detailed neurosimulations. As these models gain in size, complexity and detail, so do their computational requirements. In addition, these simulations are typically run on computer systems ranging from laptops to supercomputers and in the cloud, and must do so efficiently. This means that such complex software must be easily maintainable, to continuously provide these improvements crucial to the computational scientist’s work.
In a paper recently published in Frontiers in Neuroinformatics, the EPFL Blue Brain Project has collaborated with Yale University and the Department Physiology and Pharmacology, SUNY Downstate, New York to substantially modernize NEURON. The result is better software sustainability, improved software and hardware portability and increased simulator efficiency.
June – Does one simple rule underlie learning in the brain?
What underlies learning in the brain might be actually simpler than previously thought despite the brain being one of the most complex objects in the known universe. A collaboration of Scientists led by the EPFL Blue Brain Project has achieved a major advance in accurately simulating the synaptic changes thought to implement learning in the neocortex, opening the door to greater understanding of learning in the brain.
In a paper published in Nature Communications, a group of scientists from the EPFL Blue Brain Project, together with collaborators from Université de Montréal, Université de Paris, Hebrew University of Jerusalem, Instituto Cajal, and Harvard Medical School, introduce to the neuroscience community a model of synaptic plasticity for Pyramidal Cells (PCs) in the neocortex based on data-constrained postsynaptic calcium dynamics. By comparing their results to the available experimental data, they show that their synaptic plasticity model can capture the varied plasticity dynamics of the diverse PCs making up the neocortical microcircuit. They achieve this with only one unified model parameter set, indicating the plasticity rules of the neocortex could be shared across pyramidal cell-types.
April – Blue Brain Builds Neurons with Mathematics
EPFL’s Blue Brain Project has found a way to use only mathematics to automatically draw neurons in 3D, meaning we are getting closer to being able to build digital twins of brains.
Using algebraic topology, a field of Math, a Blue Brain team created an algorithm that requires only a few examples to generate large numbers of unique cells. Using this algorithm – the Topological Neuronal Synthesis (TNS), they can efficiently synthesize millions of unique neuronal morphologies.
November – The First Digital Reconstruction of the Neuro-Glia-Vascular Architecture
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.

June – Blue Brain Team Discovers a Multi-Dimensional Universe in Brain Networks
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.

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.

Neural simulations hint at the origin of brain waves
For almost a century, scientists have been studying brain waves to learn about mental health and the way we think. Yet the way billions of interconnected neurons work together to produce brain waves remains unknown. Scientists from Blue Brain and the Allen Institute for Brain Science showed in a paper published in journal Neuron how a complex computer model is providing a new tool to solve the mystery.
