The mechanistic basis of arousal is controversial. In this issue of Neuron, Lebestky et al.'s new study in Drosophila, where dopamine has been shown to be involved in several types of attentional processes, demonstrates that it independently regulates distinct types of arousal. These data provide evidence for molecularly convergent, but anatomically divergent, task-specific arousal circuits.
觉醒的机制基础存在争议。在本期《神经元》杂志中，莱贝茨基等人在果蝇身上开展的新研究表明，多巴胺参与了多种类型的注意力过程，该研究还证明多巴胺能独立调节不同类型的觉醒。这些数据为分子层面趋同但解剖学层面不同的任务特异性觉醒回路提供了证据。
