FAQs & ALL YOU NEED TO KNOW
Belgrade by plane
Belgrade’s main airport is Nikola Tesla Airport, located in Surčin, 18 km away from Belgrade’s city centre. There are direct flights from most major European cities as well as connections also form Asia, Africa and North America.
Belgrade by train
The centrally located Belgrade Centre Railway Station (Beograd Centar Prokop) is connected to all main cities of Europe by daily and overnight trains. There are commercial discounts available as Euro Domino, Railplus, Balkan Flexipass, Easy Travel Card, Euro 26, City Star and the unified Balkan Tariff. Find further info here: Serbian Railways
Belgrade by car
The main international roads going through Belgrade are E-70 and E-75. It is necessary to pay on several tolls on your way to Belgrade. As the local roads may lack of sufficient road signs, you should use a navigating system.
- In town: 50 km/hour.
- Outside built-up areas: 80-100 km/hour
- Motorways: 120-130 km/hour.
It is safer to book a transfer in advance, but if this is not possible, you have following possibilities:
- Public transport
The cheapest possible transfer solution is certainly a regular bus, specifically line 72 which takes up to 60 minutes and costs around 1 €. There are also minibuses available, which take you 30 to 40 minutes to Belgrade centre and cost around 2 €.
Taxis are easily available at Belgrade airport. There is also a city service TAXI INFO desk where you can take a taxi receipt with the name of your destination and appropriate pricing for the taxi service.
The average taxi’s price to the city center is around 15 € and depending on traffic takes you 20-30 minutes.
Belgrade’s public transport consists of a network of bus, trolleybus and tram routes. Tickets can be bought in the transport vehicle from the driver or conductor as well as at kiosks that are marked with a ticket sales sticker. The bus lines run every 3 to 30 minutes at daytime, whereas the night lines run every 30-60 minutes.
The closest tram/bus stop is called “Karađorđev Park” (Карађорђев парк).
In order to get to the venue from the main train station, you need to do the following:
Take bus 78 or Tram 9 (direction Banitsa) and get off at the named stop (should be the 4th stop).
Walk against the direction you came from and turn left on the first corner. Then you need to turn left again and walk along the street “Dr Subotića starijeg (др Суботића старијег)” until you see the university’s building on your right.
The walk from the bus station to the venue is about 5 minutes. You can also walk from the Train station, as this would also take you only 12 minutes.
Telephone: +38111 19804 further information
Mainly there are two different Taxi rates:
From 6 am until 10 pm it starts around €1,40 and the kilometre charge is 50cent.
From 10pm until 10am the rate also starts around €1,40, but the charge per kilometre is around 70c.
Taxis can also be stopped on the street but be careful to not catch an unlicensed taxi. In order to prohibit this, you should make sure that the taxi has a company board or unique number on the roof, a taximeter and a registration plate with the letters TX at its end.
Belgrade has a moderate continental climate, with hot humid summers and cold winters. In the time from April-October you find the sunny months in Belgrade. The daily temperature in July will be between 17 and 28° which results in a daily mean of 23°.
The main language in Belgrade is Serbian. But English is widely spoken as well. Especially in restaurants, bars, shops and other public places in the city center, you can perfectly communicate with English. Serbian belongs to the Slavic languages and besides the latin script, Serbian is also written in Cyrilic.
- Currency, credit cards, banking
The official currency is Serbian Dinar (RSD, РСД). The exchange rate is around: 1 € = 117,60 RSD. For your exchange of money, you should turn to specialized banks or one of the many exchange offices. Exchange machines accept Euro, US dollars and British pounds. Dinar is used in denominations of 10, 20, 50, 100, 200, 500, 1000 and 5000. The latest exchange rate from Euro to Dinar can be checked here. Of course you can purchase your money also directly from an ATM, which you usually find in major malls and public places. Most international credit cards (Eurocard/Mastercard, Visa, American Express) are also widely accepted.
- Time zone
Belgrade is in the Central European Time Zone (CET). In the winter months clocks are set at GMT + 1 hour and in the summer (March to end of October) GMT + 2hours.
- Electric current
Electric sockets in Serbia have a voltage of 220 Volts and a frequency of 59Hz. Adapters may be needed.

Lecture title: Welcome and introduction to the European Human Brain Project
The human brain has a multi-level organisation and high complexity. New approaches are necessary to decode the brain with its 86 billion nerve cells, which form complex networks. Ultra-high resolution models and simulation pose massive challenges in terms of data processing, visualisation and analysis. For example, high-resolution data obtained in post-mortem brains supplement information about structural and functional connectivity as obtained by Magnetic Resonance Imaging, which can be acquired from the living human brain, with a spatial resolution in the millimetre range. 3D Polarized Light Imaging elucidates the connectional architecture of the brain at the level of axons at the micrometre range, while keeping the topography of the whole organ; it results in data sets of several petabytes per brain, which should be actively accessible while minimizing their transport. By bringing together different aspects of connectivity in one and the same atlas, it is feasible to combine the advantages of the different approaches, and to address the different spatial (and temporal) scales.
The Human Brain Project is developing a multimodal human brain atlas, which integrates the information of brain organisation from multiple levels including cellular architecture, connectivity, molecular and genetic maps, and results from neuroimaging studies of the brain from healthy subjects and patients. Empirical research is supplemented by modelling and simulation, resulting in new data that is stimulating new experiments.
The Human Brain Project [1, 2] creates a cutting-edge European infrastructure to enable cloud-based collaboration among researchers coming from different disciplines around the world, to create development platforms with databases, workflow systems, petabyte storage, and supercomputers opening new perspective to decode the human brain.

Lecture title: The visual cortex: When structure meets function
Considerable technological progress in noninvasive functional investigations of the human visual cortex enabled the discovery of new visual areas and their further precise functional mapping. Since the beginning of the 1990s, the use of functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) enabled the functional mapping of 13 occipital visual areas: V1, V2, V3 (V3d/V3v), V3A, V4, VО1, V5, hMST, V6, V7, LO1, LO2. This significant scientific progress in the functional mapping of the human visual cortex was not followed by the corresponding architectonic investigations so it was not possible to establish anatomical correlates of these new functionally defined visual areas. During the past two decades, our enthusiastic and dedicated group performed cytoarchitectonic mapping of 11 occipital areas (hOc1, hOc2, hOc3v, hOc4v, hOc3d, hOc4d, hOc4la, hOc4lp, hOc5, FG1 and FG2) which are visual in their function. Continuous probabilistic maps of these cytoarchitectonic areas have been generated to characterise their location, extent, size and variability. These maps are easily available to the whole scientific community (JuBrain, Human Brain Project) and their verification is ongoing. Convergent evidence from a standpoint of location, topography, size, functional properties and connectivity suggests that these cytoarchitectonic areas are the anatomical correlates of the functionally defined visual areas.

Lecture title: Cognition and motion: Space to be fulfilled
In several studies, including one recruiting 28,808 community-dwelling adults, it has been shown an association between poor cognitive function and reduced mobility (gait, balance and chair stands). Such interdependence between mobility and cognition has been suggested to reflect age-dependent changes in shared neural mechanisms and an increased demand for cognitive monitoring in motor control with age. Indeed, safe and independent negotiation of complex environments requires integration of external sensory information with neural networks involving cortical, subcortical, brainstem, and spinal cord structures (some of these share common substrates with cognition). A substantial corpus of evidence suggests that the cognitive involvement in postural control and gait increases with aging. A large portion of such studies were based on dual-task experimental designs, which typically use the simultaneous performance of a motor task (e.g., static or dynamic balancing, walking) and a continuous cognitive task (e.g., mental arithmetic, tone detection). Resolution of similar interferences requires executive functions, which schedule processing order of the tasks, interrupt or reinstale task processing, and switch between the processing streams of the tasks. Even in cognitively normal, older adults, there is a robust association of gait speed and gait variability with executive function, attention, and (to a lesser extent) memory and visuospatial function. These associations are more emphatic under dual-task conditions. Moreover, gait impairment precedes and predicts cognitive decline and may be a more sensitive marker of cognitive decline than cognitive tests.
We have examined this association in patients with Parkinsonʼs disease (PD) using gait and freezing of gait (FoG) as models. In PD patients during the mental dual-task we observed furher deterioration in gait parameters which reflect gait automaticity (eg. an increase in stride variability and gait asymmetry, in parallel with decrease in gait rhythmicity). In PD patients with FoG we conducted multimodal MRI investigations and found (a) functional decoupling between coordinated motor and cognitive neural networks (“interference model” of FoG) and (b) altered functional connectivity not only in the locomotor but also in “cognitive” circuits such as the attention-related frontoparietal and visual occipito-temporal networks („network-wide dysfunction“).

Lecture title: Hands-on session I: Open Science: How to
Open Science is a continuation of practices which began centuries ago with the advent of academic journal publications. The most recent developments in Open Science is Open Data, recently made possible by new technological capabilities to store large amounts of data, and to access and work on the data online. Leading journals are already now requiring posting of research data in public repositories, to complement the traditional journal article containing the interpretations of the data. Several general data repositories for sharing of research data are available – however, many lack the necessary stewardship and standards for making the research data easy to Find, Access, Interpret, and Re-use, in accordance with the FAIR principles (Wilkinson et al., Scientific Data 3:160018, 2016). To address these challenges, the Human Brain Project is developing a new research infrastructure, the EBRAINS FAIR data service, providing tools, workflows and data curation services tailored for integration and sharing of heterogeneous, multimodal neuroscience data and computational models. Three-dimensional open-access brain reference atlases provide the anatomical context for all data shared via the EBRAINS infrastructure, easing comparison and interpretation of findings.

Lecture title: Introduction to the HBP Collaboratory
The Human Brain Project (HBP) Collaboratory is a central directory for tools developed by the HBP Platforms. At the core of the Collaboratory are Collabs. These are spaces designed for collaborative work where users can contribute content, integrate applications and run Jupyter notebooks. Collabs have at least a team, a landing page, and a navigation menu. As a user, you can organise content, which can be text or documents, manage the team members you want to work with and add interactive tools. The Collaboratory is a tool to help with the dissemination of science, collaboration, and project management. In this presentation, I will introduce the project and the vision behind it, show you where to find information, give a demo of the HBP Collaboratory's features and present how to build a shared workspace for a simple project.
Lyuba Zehl studied Biology (BSc) and Neuroscience (MSc) at the University of Cologne under the supervision of Prof. Ansgar Büschges and Prof. Wolfgang Walkowiak, respectively. During this time of study, she worked on kinematic of insect legs during locomotion (BSc thesis), optimisation of peripheral nerve implantation of multi-electrode arrays in small mammals (internship at Blackrock Microsystems and the Center of Neural Interfaces of the University of Utah, USA), and the anatomical cartography of auditory nuclei in the brain stem of toothed whales using cluster analysis (MSc thesis). For her doctoral studies, she switched to RWTH Aachen University and joint the Statistical Neuroscience Group of Prof. Sonja Grün at the Institute for Neuroscience and Medicine (INM-6) of the Jülich Research Centre. In her thesis, she worked on analysing multi-electrode array recordings of monkey motor cortex and, in particular, on data and metadata management of complex neuroscience experiments. After receiving her doctorate degree (Dr. rer. nat.) in 2017, she started working as a junior scientist half-time under Timo Dickscheid in the Big Data Analytics Group at the INM-1 of the Jülich Research Centre and Molecular and half-time under Prof. Björn Kampa in the Systemic Neurophysiology Group at the Institute of Biology II at RWTH Aachen University. Since May 2019, she has worked full time in the Big Data Analytics Group at the INM-1 for the curation team of the Neuroinformatics Platform of the Human Brain Project (HBP). Having a high interdisciplinary orientation towards computational neuroscience and software development for data and metadata management and a broad experience in various neuroscience laboratories, she now focuses on developing and implementing concepts, standards and tools for neuroscience data and metadata management. With her current work, she strongly supports the integration of heterogeneous neuroscience data into the unified data sharing platform and the interactive atlas viewers of the HBP.
Lecture title: Hands-on session III: The HBP Human Brain Atlas: Integration and visualisation of heterogeneous neuroscience data
As a part of the Neuroinformatics Platform, the Human Brain Project (HBP) is developing a comprehensive multi-level Human Brain Atlas. This novel atlas consists of web-based services that allow users to discover, explore and access a unique selection of anatomical reference spaces and high-quality structural parcellations, down to a microscopic resolution. A diverse range of well curated human brain data at different scales and modalities is linked to this atlas, and can be discovered and downloaded by browsing brain regions. For integrating new data to the atlas, the platform provides support and tools for metadata curation, and spatial anchoring of non-image, 2D and 3D image data to the reference atlases. A rich interactive viewer allows users to display common types of data in anatomical context together with the reference atlas delineations (e.g., JuBrain cytoarchitectonic atlas, BigBrain microscopic model). During the hands-on session, participants learn how the BigBrain reference model can be interactively explored in 3D using the interactive atlas viewer, and how non-image data can be semantically linked to the JuBrain reference atlas, using cortical receptor densities as an example. We will also demonstrate spatial anchoring of 2D and 3D image data to the HBP’s reference atlases.
Kai Kiwitz graduated in Psychology and Cognitive Neuroscience at the Universities of Düsseldorf and Bochum in 2016. Since then, he performs his PhD work at the Cécile and Oskar Vogt Institute of Brain Research at the University of Düsseldorf under the supervision of Prof. Katrin Amunts in close collaboration with the Big Data Analytics Group led by Dr. Timo Dickscheid at the INM-1 of the Jülich Research Centre. In his research, Kai evaluates the use of machine learning solutions aimed at aiding neuroscientists in high-resolution cytoarchitectonic mapping approaches in the BigBrain. He is especially interested in analysing representations of cytoarchitectonic features within Convolutional Neural Networks to validate their use in the generation of a high-resolution anatomical reference framework of the human visual system.

Marta Turégano is a PhD student at the Cajal Laboratory of Cortical Circuits directed by Prof. Javier DeFelipe in Madrid (Spain). She holds a degree in Biology and a Master’s degree in Neuroscience by the Universidad Autónoma de Madrid. During those stages she learnt 3D electron microscopy techniques applied to the exploration of the ultrastructure of the brain. Currently, her research is focused on the description of the mouse somatosensory cortex, the synapses, axons, dendrites and organelles placed in these neuronal compartments. Her work is part of the subproject 1 “Mouse Brain Organisation” of the Human Brain Project. In addition, she is the SP1 Student Ambassador, in which function she promotes the events of HBP aimed at the student community.
Lecture title: Microanatomy of the brain: A critical step to model neuronal circuits
Most cortical synapses are established in the neuropil, which is composed of dendrites, axons and glial processes. There are two basic types of synapses: excitatory (glutamatergic) and inhibitory (GABAergic). It is important to describe the morphology of both kind of synapses, as well as their density and location, because these parameters have a functional correlate. In addition, we have studied the organelles placed on these neuronal compartment as mitochondria, spine apparatus and multivesicular bodies (MVBs) and their possible relation with synapses. For that purpose, we used three-dimensional electron microscopy with combined focused ion beam milling and scanning electron microscopy (FIB/SEM), a method that allows us to obtain long series of consecutive sections in an automated way. These stacks of serial sections can later be examined and segmented in 3D with dedicated software called Espina. We have created a new tool of Espina to trace the fibers across the stacks of EM images, acting as the skeletons of different compartments in the sample. Besides qualitative information, we extract morphological information about the length, density and connectivity of dendrites, axons and the synapses among them.
This work provides accurate quantitative data that helps understand the mouse cortical circuitry and will be very useful to refine and validate current cortical models.
