女性的交流行为往往被研究人员忽视，而倾向于男性的行为，因为男性的行为通常更公开，更容易引发。棕色幽灵刀鱼是一种弱电波型裸体鱼类，对其雌性电通讯行为知之甚少。大多数行为研究都集中在雄鱼身上，鱼通常会受到限制，并在自己的电子器官放电频率附近施加刺激，以唤起啁啾(短期频率的突然上升)或干扰回避反应。我们的研究集中于分类和描述自由游泳雌性鱼的自发和诱发的电器官放电调制，这些雌性鱼要么电耦合到装有同种(雄性或雌性)的水箱，要么保持隔离。对孤立和社会条件下产生的信号进行聚类分析，发现三种类型的上升：短上升、中等上升和长上升；以及一种频率下降(下降)。当雌性与包含低频雌性的坦克电耦合时，产生明显更多的短上升，而当与包含雄性的坦克电耦合时，产生更多的长上升。短上升可能具有性内攻击性功能，而长上升可能在两性互动中作为地位或生殖条件的广告。
Female communication behaviors are often overlooked by researchers in favor of male behaviors, which are usually more overt and easier to elicit. Very little is known about female electrocommunication behaviors in brown ghost knifefish, a weakly electric wavetype Gymnotiform fish. Most behavioral studies have focused on males, and fish are usually restrained and played a stimulus near their own electric organ discharge frequency to evoke chirps (abrupt short-term frequency rises) or the jamming avoidance response. Our study focuses on categorizing and describing spontaneous and evoked electric organ discharge modulations in free-swimming female fish that were either electrically coupled to tanks containing a conspecific (male or female), or left isolated. Cluster analysis of signals produced under isolated and social conditions revealed three categories of rises: short rise, medium rise and long rise; and one category of frequency decrease (dip). Females produce significantly more short rises when electrically coupled to tanks containing lower-frequency females, and produce more long rises when electrically coupled to tanks containing males. Short rises may have an intrasexual aggressive function, while long rises may serve as an advertisement of status or reproductive condition in intersexual interactions.
