CET: 09:00 UTC: 08:00 | Simulate with EBRAINSHow to use EBRAINS research infrastructure and Fenix resources for simulations on a scale from molecules via small and large networks of point or structured spiking neurons to simplified whole brain activity and virtual environments.![]() AbstractThis online workshop aims at giving an overview of how to simulate with EBRAINS, from the infrastructure level to simulations at multiple scales. It covers a large variety of topics, e.g. computing and data services of or related to the Fenix infrastructure, Neuromorphic Computing, and simulations on a scale from molecules via small and large networks of point or structured spiking neurons to simplified whole brain activity and virtual environments Participants can choose from a large number of sessions what is relevant for them. The first day will be a short workshop about the Fenix User and Resource Management Service (FURMS) and the Fenix Authentication & Authorisation Infrastructure (AAI). The second day will start with the official welcome session, followed by introductions to the different topics of this workshop and to put tools and simulators into relation with each other. These introductions also serve the purpose to help the participants to update their choice of sessions for the following days. This day will conclude with a hands-on introduction to the EBRAINS Collaboratory environment, a web-portal through which many services and tool are available, and which will be used by several sessions on the following days. The last two days are organised with multiple sessions taking place in parallel, in which the tools and services will be presented in more detail, with lectures and/or as hands-on tutorials. RegistrationThe event is free of charge, but registration is necessary.

NEST DesktopNEST Desktop is a web-based graphical user interface (GUI) for the NEST Simulator. The GUI guides users to understand the script code for NEST Simulator. The aim of NEST Desktop is an application which should be intuitive and easy to learn for newcomers, but also attractive for experienced users to perform sophisticated simulations. In this session, we will learn typical steps of a virtual experiment with spiking network model:
By the end of the session we will demonstrate the concept of the client-server architecture in which NEST Desktop is the client and NEST Simulator is the backend server. TVBWe demonstrate the TVB-EBRAINS integrated end-to-end personalized brain simulation workflows in the Cloud (Schirner et al. 2022) that can be reached via EBRAINS The Virtual Brain Cloud: https://ebrains.eu/service/the-virtual-brain/. Attendees can work jointly in a dedicated collaboratory during the hands-on-session. Electrical model building toolsetIn this session, you will build a biologically detailed neuron model using the NEURON simulator and three open source python packages: eFEL, BluePyEfe and BluePyOpt. First, a short lecture will describe the process of extraction of electrical features from experimental patch-clamp recordings as well as the algorithms used for the creation of the numerical models. Then, during a hands-on session, biological data will be made available and will be used as target for the creation of one or several electrical neuron models. | ||||||||||

NESTMLNESTML is a domain-specific language for neuron and synapse models. These dynamical models can be used in simulations of brain networks on several platforms, in particular NEST Simulator. NESTML combines an easy to understand, yet powerful syntax with a flexible processing toolchain, written in Python, and good simulation performance by means of code generation (C++ for NEST Simulator). In this tutorial, you will get hands-on experience creating new neuron and synapse models, instantiating them in a NEST simulation, and doing analysis on the recorded data. We will cover creating a compartmental neuron model with an active dendrite, adding stochasticity to a model, and several synaptic plasticity models such as spike-timing dependent plasticity (STDP) and third-factor plasticity rules. Using the PyNN library to build and simulate spiking neural network models on EBRAINSPyNN is a simulator-independent Python library for building neuronal network models. Models built with the PyNN API can be simulated without any code modifications on any simulator that PyNN supports (currently NEURON, NEST, and Brian), and on the SpiNNaker and BrainScaleS neuromorphic hardware systems. This allows users to:
Participants will learn how to access different simulation tools in the EBRAINS Lab; how to build spiking network models with PyNN, how to run simulation experiments with NEST, NEURON, Brian and SpiNNaker, and how to visualize the results. | ||||||||||

Health Data CloudThis session will provide an introduction to EBRAINS Service for Sensitive Data - the Health Data Cloud (HDC). We will demonstrate the technical and organizational measures to provide data protection by design and by default according to the EU general data protection regulations (GDPR). Features such as the GUI, command line interface, gateway to HPC, workbench tools, etc. will be demonstrated. We also plan a hands on session where attendees can experience HDC functionality on their own. ArborArbor is a portable, high-performance library for computational neuroscience simulations with multi-compartment, morphologically-detailed cells, ranging from single cell models to very large networks. Optimisations make Arbor an order of magnitude faster than the most widely-used comparable simulation software. Download Arbor as a C++ library and integrate it in your own program, or install it as a Python library (through pip) and import in any Python script. MUSICMUSIC is a tool for co-simulation in the computational neuroscience domain. It supports simulations where different parts of a model is simulated by different instances of a simulator or different simulators and/or other software or hardware. MUSIC supports large-scale simulations on clusters but can be run on a desktop or laptop as well. In this session, participants will be introduced to the PyNN/MUSIC interface which allows MUSIC co-simulations to be specified by a single PyNN script. Co-simulations involving NEST and NEURON as well as SpiNNaker and a virtual environment will be demonstrated. | ||||||||||

Macromolecular flexibility databases; Setting up & running Molecular Dynamics (MD) simulationsThe session will present and describe macromolecular flexibility databases integrated in the EBRAINS infrastructure (MoDEL-CNS, CNS ligands, BioExcel-CV19), built from information extracted from Molecular Dynamics (MD) simulations. The hands-on session will be focused on setting up and running a MD simulation. NeuroroboticsThe Neurorobotics Platform (NRP) is a set if software tools that was specifically developed to enable its users to connect brain models to embodied agents interacting with a simulated environment. V4.0 of the NRP emphasizes its function as an integrative ecosystem capable of orchestrating multiple simulation engines and heterogeneous control components in a distributed manner. This session will introduce NRP v4.0 and showcase how it can be used for multi-engine simulations, learning experiments, and soft real-time simulations. | ||||||||
