Supercomputing facilities are becoming increasingly available for simulating activity dynamics in large-scale neuronal networks. On today's most advanced supercomputers, networks with up to a billion of neurons can be readily simulated. However, building biologically realistic, full-scale brain models requires more than just a huge number of neurons. In addition to network size, the detailed local and global anatomy of neuronal connections is of crucial importance. Moreover, anatomical connectivity is not fixed, but can rewire throughout life (structural plasticity)-an aspect that is missing in most current network models, in which plasticity is confined to changes in synaptic strength (synaptic plasticity). The papers in this Ebook, which may broadly be divided into three themes, aim to bring together high-performance computing with recent experimental and computational research in neuroanatomy. In the first theme (fiber connectivity), new methods are described for measuring and data-basing microscopic and macroscopic connectivity. In the second theme (structural plasticity), novel models are introduced that incorporate morphological plasticity and rewiring of anatomical connections. In the third theme (large-scale simulations), simulations of large-scale neuronal networks are presented with an emphasis on anatomical detail and plasticity mechanisms. Together, the articles in this Ebook make the reader aware of the methods and models by which large-scale brain networks running on supercomputers can be extended to include anatomical |

Sommario/riassunto |
|
Heiko Schmid beschäftigt sich mit so unterschiedlichen und gleichzeitig faszinierenden Phänomenen wie der populären Astronomie, der Künstlerbewegung der Futuristen, dem Science-Fiction-Genre, den Entstehungszusammenhängen der Raketentechnologien und dem Theorem der vierten Dimension. All diese vielfältigen Themenfelder verbindet er hierbei mit einer Annäherung an das Konzept der Maschine. Das zentrale Anliegen der Studie ist es, den Maschinenbegriff kultur- und kunsthistorisch in einen komplexen Rahmen technoimaginativer Entwicklungen einzubetten. |
»Heiko Schmid zeigt uns seine Sterne. Mit seiner Dissertation führt er unseren Blick, kulturhistorisch, philosophisch, populärwissenschaftlich und künstlerisch gelenkt, in den Kosmos.« |
