    Explore the captivating world of brain simulation as we offer you a glimpse of an exclusive interview with Prof. Petra Ritter, our group leader, and renowned neuroscientist. This illuminating conversation, conducted in the German language, is part of the 'Zoomposium Series'.

    The Zoomposium Series

    The Zoomposium Series, organized by Dirk Boucsein (philosophies.de) and Axel Stöcker (die-grossen-fragen.com), aims to provide the public with free, accessible, and engaging popular scientific and philosophical content from diverse areas, including cognitive neuroscience, philosophy of the mind, and the theory of science.

    A Fascinating Journey Awaits

    In this brief overview, we provide you with insights from Prof. Ritter, as she guides us through the intricate landscape of brain simulation. You'll get a taste of the pioneering work that is shaping the future of neuroscience.

    The Virtual Brain: A Gateway to Understanding

    Prof. Ritter is at the forefront of innovation through her leadership in the co-design project known as The Virtual Brain. This groundbreaking endeavor, an integral part of the European Open Science Cloud (EOSC), stands as a remarkable neuroinformatics platform. It allows for the simulation of complete brain networks with biologically realistic connectivity, opening unprecedented doors to understanding the complexities of the human brain.

    A Trailblazer in Brain Research

    Notably, Prof. Ritter's contributions extend beyond individual projects. She plays a central role in the German National Research Infrastructure Initiative Neuroscience (NFDI-Neuroscience) and actively contributes to the development of the EBRAINS Health Data Cloud. Her dedication is propelling the field of brain research into uncharted territories, fostering collaboration and innovation.

    Exploring the Intricate Methods

    During this captivating interview, we embark on a journey through Prof. Ritter's methods and methodologies. Her work involves intricate correlations between empirical data from MRI, EEG, PET scans, and neurotransmitter concentrations, woven together with mathematical models. This synthesis of data and computation allows her to emulate neural processes within the brain with remarkable precision.

    From Paradigm Shifts to Synchrony

    Prof. Ritter's holistic approach to research challenges traditional cognitive neuroscience paradigms. By constructing group/population models from multiple nerve cells, she takes into account their synchrony—a methodology that challenges the conventional 'bottom-up' approach. The discussion extends into the intriguing realm of neuronal activity patterns, their synchrony, and their profound implications for understanding brain dynamics.

    Transcending Theory to Practical Applications

    While her research has strong foundational aspects, it also extends into practical applications for neurosurgical therapies and neurological diagnostics. Prof. Ritter integrates 'functional circuits' into individual brain models, shedding light on working memory, decision-making, and other cognitive processes. This interdisciplinary approach holds the potential to unravel the mysteries of cognition.

    A Gateway to Artificial Intelligence

    The Human Brain Project (HBP) has been instrumental in advancing the field, with projects like the 'Virtual Brain Project' within EBRAINS. These initiatives have pushed the boundaries of brain simulation, generating 'microconnectomes' and exploring the intricate world of the brain. Prof. Ritter's insights into the future direction of these projects and their potential intersections with artificial intelligence add an extra layer of intrigue to the conversation.

    Unraveling the Enigma of Consciousness

    The interview doesn't shy away from profound questions. If we were to achieve the perfect simulation of a human brain, what would that mean for our understanding of consciousness? Would it create a 'synthetic human,' or is a simulation, no matter how perfect, always just that—a simulation?
