    "abstract": "We studied the stability of linear vortex filaments in 3-dimensional (3D)\nexcitable media, using both analytical and numerical methods. We found an\nintrinsic 3D instability of vortex filaments that is diffusion-induced, and is\ndue to the slower diffusion of the inhibitor. This instability can result\neither in a single helical filament or in chaotic scroll breakup, depending on\nthe specific kinetic model. When the 2-dimensional dynamics were in the chaotic\nregime, filament instability occurred via on-off intermittency, a failure of\nchaos synchronization in the third dimension.",
