What's the link between epileptic seizures and earthquakes, basic and applied research?

A recent preprint describes two kinds of phenomena in terms of coupled threshold oscillators - earthquakes and epileptic seizures. It turns out that methods developed for earthquake prediction may become useful in predicting seizures:

Besides, it may be a good starting point to discuss the interdisciplinary aspects of basic and applied research, e.g. how to write or to review grant proposals on cross-disciplinary topics.
