Report

Selective attention allows to process stimuli which are behaviorally relevant, while attenuating distracting information. However, it is an open question what mechanisms implement selective routing, and how they are engaged in dependence on behaviora

Report

Strong attentional modulation of V1/V2 activity implements a robust, contrast-invariant control mechanism for selective information processing

Autor: Rausch, Lukas-Paul, Schünemann, Maik, Drebitz, Eric, Harnack, Daniel, Ernst, Udo A., Kreiter, Andreas K.

When selective attention is devoted to one of multiple stimuli within receptive fields of neurons in visual area V4, cells respond as if only the attended stimulus was present. The underlying neural mechanisms are still debated, but computational stu

Report

A rigorous stochastic theory for spike pattern formation in recurrent neural networks with arbitrary connection topologies

Autor: Schünemann, Maik, Ernst, Udo, Kesseböhmer, Marc

Cortical networks exhibit synchronized activity which often occurs in spontaneous events in the form of spike avalanches. Since synchronization has been causally linked to central aspects of brain function such as selective signal processing and inte
