What's next for the neurobiology of temperament, personality and psychopathology?

This paper represents the outcome of a multidisciplinary discussion on what works, what doesn't, and what can be improved, in on-going work on bio-behavioural taxonomies and their biomarkers. The authors of this paper, representing a wide spectrum of bio-behavioural disciplines (clinical, developmental, differential psychology, neurophysiology, endocrinology, psychiatry, neurochemistry, neurosciences), have contributed more extensive opinions to the Theme Issue "Neurobiology of temperament, personality and psychopathology: what's next?". The authors identified ten directions in international and multidisciplinary cooperation, and multiple insights for "what is next" for each of these directions.
