Neural activity in self-identified claustrophobic individuals under in-vivo stimuli: A human electroencephalography dataset

The electrocortical activity in claustrophobic situations is a very limited field of study and has recently caught researchers’ attention. This article represents a set of electroencephalographic (EEG) data obtained from twenty-two participants. The volunteers include 9 participants with self-identified claustrophobia and 13 healthy controls under in-vivo stimuli. The EEG data were recorded using Mitsar 31-channel EEG system. Before cortical signal recording, Individuals were asked to identify themselves as healthy controls or claustrophobic participants. The EEG data collection process consisted of three experimental conditions. In all conditions, the participants were asked to stay calm and keep their eyes open. The first experimental condition was at seated resting state in a relatively large and well-lit laboratory (8m x 15m) area. In the second experimental condition, the subjects entered a moderately-lit chamber and repeated the previous resting situation. The final condition of the EEG data acquisition was performed in the same chamber but with reduced dimensions. For each experimental condition, duration of data collection was approximately 300 seconds. This data can be used to understand the brain's response in claustrophobic situations through various statistical or data-driven methods.幽闭情境下的脑皮层电活动是一个研究相对匮乏的领域，近期逐渐受到研究者的关注。本文所呈现的是一组来自22名受试者的脑电图（electroencephalographic, EEG）数据。受试者包含9名自我报告患有幽闭恐惧症的参与者与13名健康对照者，所有受试者均接受了实景刺激。本次脑电数据采用Mitsar 31通道脑电采集系统进行记录。在采集皮层信号前，要求受试者自行声明自身属于健康对照者还是幽闭恐惧症参与者。脑电数据采集流程包含三种实验条件，所有实验条件下均要求受试者保持平静并睁眼。第一种实验条件为：受试者在一间面积约8米×15米、宽敞明亮的实验室区域内取坐姿静息。第二种实验条件中，受试者进入一间光线适中的密闭舱室，重复前述静息状态。第三种实验条件在同一密闭舱室内开展，但舱室空间尺寸有所缩减。每种实验条件下的数据采集时长均约为300秒。本数据集可通过各类统计方法或数据驱动方法，用于探究大脑在幽闭情境下的响应机制。
