Despite the constant improvement of algorithms for automated brain tissue classification, the accurate delineation of subcortical structures using magnetic resonance images (MRI) data remains challenging. The main difficulties arise from the low gray-white matter contra...

Putting Actions in Context: Visual Action Adaptation Aftereffects Are Modulated by Social Contexts

Article English OPEN

(2014)

Publisher: Public Library of Science

The social context in which an action is embedded provides important information for the interpretation of an action. Is this social context integrated during the visual recognition of an action? We used a behavioural visual adaptation paradigm to address this question ...

Neural Networks as Sources of uncorrelated Noise for functional neural Systems

Conference object English CLOSED

Jordan, Jakob; Petrovici, Mihai; Tetzlaff, Tom; Pfeil, Thomas; Breitwieser, Oliver; Bytschok, Ilya; Bill, Johannes; Gruebl, Andreas; Schemmel, Johannes; Meier, Karlheinz; Diesmann, Markus;

Neural-network models of brain function often rely on the presence of noise [1,2]. Yet thebiological origin of this noise remains unclear. In computer simulations and in neuromorphichardware [3,4], the number of noise sources (random-number generators) is limited. In co...

Long-Term Spatiotemporal Reconfiguration of Neuronal Activity Revealed by Voltage-Sensitive Dye Imaging in the Cerebellar Granular Layer
