Paradoxical dopaminergic drug effects in extraversion: dose- and time-dependent effects of sulpiride on EEG theta activity.

abstract：:Separable affix verbs consist of a stem and a derivational affix, which, in some languages can appear together or in discontinuous, distributed form, e.g., German "aufgreifen" and "greifen … auf" ["up-pick(ing)" and "pick … up"]. Certain stems can combine with only certain affixes. However, many such combinations are ...
