One indication of receptive behavior of the female leopard frog, Rana pipiens, is absence of a release call during tactile stimulation of the trunk. Prostaglandin E2 (PGE2) inhibits this call. This experiment demonstrates a different pattern of [14C]2-deoxyglucose concentration in brains of 5 receptive females silenced by 1 microgram/g PGE, compared with that in 3 unreceptive, vocalizing controls injected with deionized water. 14C concentrations were measured in areas important for vocalization in frogs, in limbic system structures and in parts of the brain that receive somatosensory input. There was high activity relative to the rest of the brain in the receptive, silent PGE2-treated females in the caudal part of the anterior preoptic nucleus, in the dorsal habenula, and in the dorsal tegmental area of the medulla lateral to the pretrigeminal nucleus.
雌性豹蛙（北美豹蛙）接受行为的一个指标是，在对其躯干进行触觉刺激时不发出释放叫声。前列腺素E2（PGE2）会抑制这种叫声。本实验表明，与3只注射去离子水、未接受刺激且发出叫声的对照雌性豹蛙相比，5只接受刺激且被1微克/克PGE2抑制发声的雌性豹蛙大脑中[14C]2-脱氧葡萄糖的浓度分布模式不同。在对青蛙发声很重要的区域、边缘系统结构以及接收躯体感觉输入的部分脑区测量了14C浓度。在接受刺激、沉默的PGE2处理雌性豹蛙中，视前核前部尾侧、背侧缰核以及三叉神经前核外侧延髓的背侧被盖区相对于大脑其他部分有较高的活性。
