总结卵沉积行为分析从延时记录，在此期间，“自发”放电的神经内分泌袋细胞记录与长期植入袖带电极。在实验室中，巴西黑腹蛛通常以特征性的“8字”图案在基底上存款长的卵带，类似于在自然环境中观察到的卵块的构型。与卵沉积相关的明显行为是有节奏的头部运动，包括与特征性相对摆动重叠的三个组成部分：上下“波动”，左右“编织”和进出“捣”。这三种行为的特征及其相对于卵在基底上出现的时间进程表明，起伏准备基底，编织分布卵警戒线和夯实将警戒线连接到基底。同样有节奏的头部运动也引起注射均质化的腹神经节（HAG）含有袋细胞簇，具有可比的“相对”潜伏期和最大频率，但总持续时间较短。正常情况下的明显行为开始早于触发产卵，通常在袋细胞激素的“自发”释放之前。这表明，在完整的动物头部振荡通常不是由袋细胞活动。在HAG注射或自发袋细胞放电后，在基底上出现卵警戒线的平均潜伏期是相同的（约34分钟），证实了先前的建议，即袋细胞放电触发排卵。此外，头部运动似乎在释放或注射激素后同时终止。随附的论文表明，袋细胞注射的行为效应的充分表达取决于卵子在生殖道中的正常运动。
SummaryEgg deposition behaviors are analyzed from time-lapse recordings during which “spontaneous” discharges of the neuroendocrine bag cells are recorded with chronically implanted cuff electrodes. In the laboratory,Aplysia brasiliana normally deposit long egg cordons on the substrate in a characteristic “figure 8” pattern similar to the configuration of egg masses observed in the natural environment. The overt behaviors associated with egg deposition are rhythmic head movements consisting of three components that overlap with characteristic relative latencies: up-and-down “undulations”, side-to-side “weaves” and in-and-out “tamps”. The characteristics of the three behaviors and their time courses relative to the appearance of eggs on the substrate suggest that undulations prepare the substrate, weaves distribute the egg cordon and tamps attach the cordon to the substrate. The same rhythmic head movements are also elicited by injections of homogenized abdominal ganglia (HAG) containing bag cell clusters, with comparable “relative” latencies and maximum frequencies but for shorter total durations. The overt behaviors begin earlier for normal than for triggered egg laying, often before the “spontaneous” release of bag cell hormones. This suggests that the head oscillations in intact animals are not normally initiated by bag cell activity. The mean latency to the appearance of the egg cordon on the substrate is the same (about 34 min) following either HAG injections or spontaneous bag cell discharges, confirming previous suggestions that the bag cell discharge triggers ovulation. Furthermore, the head movements appear to terminate at the same time following release or injection of hormone. The accompanying paper demonstrates that the full expression of the behavioral effects of bag cell injections depend upon normal movement of eggs in the reproductive tract.
