Dopamine Gene Profiling to Predict Impulse Control and Effects of Dopamine Agonist Ropinirole.

abstract：:We investigated the sources of dual-task costs arising in multisensory working memory (WM) tasks, where stimuli from different modalities have to be simultaneously maintained. Performance decrements relative to unimodal single-task baselines have been attributed to a modality-unspecific central WM store, but such cost...
