Rats that learn to vocalize for food reward emit longer and louder appetitive calls and fewer short aversive calls; Wardak et al.

Raw data from rats’ training to vocalize in 50-kHz ultrasonic calls (50-kHz ultrasonic vocalizations, USV) for food reward in operant conditioning. Rats were trained in six different ways (protocols 1-6), percent of rewards obtained and sessions’ duration was measured (Fig. S1). Also, percent of successful nosepokes and session duration were measured in the control experiment (Fig. S1). Based on USV-training sessions, the rats were divided into potential learners (20%) and non-learners; and into further sub-groups. Measured were: percent of rewards, call rate, session duration (Fig. 3); percent of rewarded USV in all USV, and in all 50-kHz calls (Fig. 4); duration and amplitude of 50-kHz USV (Fig. 5); and percentage of short 22-kHz USV in all USV (Fig. 6).

本数据集收录了实验鼠在操作性条件反射中，为获取食物奖励而进行50千赫兹超声波叫声（50-kHz超声波发声，USV）训练的原始数据。实验鼠接受了六种不同的训练方式（方案1-6），并测量了获得奖励的百分比及训练会话的持续时间（图S1）。此外，在对照组实验中，还测量了成功的鼻尖点击百分比及会话持续时间（图S1）。基于USV训练会话，实验鼠被分为潜在学习者（占20%）和非学习者，并进一步划分为亚组。测量指标包括：奖励百分比、叫声频率、会话持续时间（图3）；所有USV中奖励性USV的百分比，以及所有50-kHz叫声中的奖励性USV百分比（图4）；50-kHz USV的持续时间和幅度（图5）；以及所有USV中短时22-kHz USV的百分比（图6）。
