Behavior frames and observer judgments from 24 rats (12 females) receiving Pavlovian fear discrimination

Twenty-four Long Evans rats (12 females) received multi-cue Pavlovian fear discrimination in standard Med Associates boxes. Discrimination took place over a baseline of reward seeking and consisted of 10-s auditory cues predicting unique foot shock probabilities: danger (p=1), uncertainty (p=0.25), and safety (p=0). TTL-triggered, GigE cameras were programmed to capture 25 behavior frames before and 50 frames during cue presentation. 86,400 frames (1,152 trials) were captured during early (session 2), middle (session 8), and late discrimination (session 16). This data set consists of 1,152 PowerPoint files and 1,152 excel files, corresponding to the 1,152 single trials. Each PowerPoint is a sequence of 75 jpegs captured before (1-25) and during (26-75) cue presentation for that trial. Every PowerPoint file has a corresponding Excel file. Both file types are named by subject_session_trial. 01_08_15 = rat #1, session #8, trial #15. Each Excel file is a string of 75 observations, corresponding exactly to the 75 PowerPoint frames. Additional files included in the MetaData section. ‘Subject information’ provides date of birth, sex, and body weight for each subject. ‘Trial identity’ provides trial type identity (danger, uncertainty, or safety) for each of the 16 trials in a session. Each session is a tab and the 16 rows in each tab correspond to the 16 trials in that session. ‘Behavior definitions’ defines each behavior quantified.本数据集的实验对象为24只Long Evans大鼠（其中雌性12只），所有大鼠均在标准Med Associates实验箱中完成多线索巴甫洛夫恐惧辨别任务。该辨别任务以奖励寻求行为作为基线范式，包含10秒时长的听觉线索，不同线索对应不同的足底电击概率：危险组（电击概率p=1）、不确定组（p=0.25）以及安全组（p=0）。由TTL触发的千兆以太网（GigE）相机经预设程序设置，可在线索呈现前捕获25帧行为图像，线索呈现期间捕获50帧行为图像。在训练早期（第2次会话）、中期（第8次会话）与晚期（第16次会话）阶段，共捕获86400帧图像，对应1152次试次。本数据集包含1152个PowerPoint文件与1152个Excel文件，一一对应这1152次单试次实验。每个PowerPoint文件包含75张JPEG图像序列，对应单次试次中线索呈现前（第1至25帧）与线索呈现期间（第26至75帧）捕获的行为图像。每份PowerPoint文件均对应一份Excel文件，两类文件均采用"subject_session_trial"格式命名，例如"01_08_15"代表编号1的大鼠、第8次训练会话、第15次试次。每份Excel文件包含75条观测数据，与该试次对应的75张PowerPoint图像帧完全一一对应。元数据（MetaData）部分包含额外补充文件："受试者信息"表记录每只实验大鼠的出生日期、性别与体重；"试次标识"表记录单次训练会话内16次试次的任务类型（危险、不确定或安全），每个训练会话对应Excel文件中的一个工作表（tab），工作表内的16行数据分别对应该会话的16次试次；"行为定义"表则对所有量化分析的行为类型进行明确定义。
