Extracellular recordings of the metacerebral cell (MCC), a serotonergic neuron in Aplysia, were obtained in free moving, undrugged animals. MCC activity was evoked by exposure to food. Arousal level was manipulated by satiating the animals or exposing them to a noxious stimulus. We found that the amount of evoked MCC activity correlated with the level of arousal of the animal.
在自由活动、未用药的海兔中，对其大脑后叶细胞（MCC，一种5-羟色胺能神经元）进行了细胞外记录。通过给予食物来诱发MCC活动。通过使动物饱足或使其暴露于有害刺激来控制觉醒水平。我们发现，诱发的MCC活动量与动物的觉醒水平相关。
