How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

So far it has been impossible to compare large sets of syntactic constructions in large sets of languages systematically and automatically. The online availability of parallel text corpora and software tools to align, enrich, search and analyse them has the potential to make automatic massive systematic…

The coronacrisis makes painfully clear that a transboundary crisis requires a transboundary response. The European Union could play a key role, but that has not happened so far. Political scientist Amy Verdun (Leiden University) explains why.
