Abstract

Finger am Puls: In einem System aus zwei pulsgekoppelten Belousov-Zhabotinsky-Oszillatoren führen eine Zeitverzögerung oder die Verstärkung der Kopplungsstärke zu neuen dynamischen Phänomenen (siehe Bild; Oszillatoren rot/blau), z. B. einer schnellen gegenphasigen Oszillation. Diese Phänomene, die bei diffusiv gekoppelten Systemen nicht vorkommen, geben Hinweise, wie eine solche Pulskopplung an Synapsen erfolgt.
