PsPM-SSNA_1-2: Sudomotor Nerve Activity and Skin Conductance Response to 1: Aversive Sounds and 2: Auditory Oddballs

This dataset includes skin conductance response (SCR) and sudomotor neurography signals for each of 7 healthy unmedicated participants 4 male, 3 female,23.7+/-4.0 years) in response to 20 broadband white noise sounds (SSNA_1) or 10 oddball tones in a oddball task (SSNA_2). Some participants did not complete SSNA_2 or had several repetitions of SSNA_1 such that there are 9 recordings for SSNA_1 and 5 recordings for SSNA_2. White noise sounds in SSNA_1 were 1 s long with 10 ms on- and offset ramp and presented at ~85 dB. Oddball and standard sounds in SSNA_2 were 50 ms long, with 10 ms on- and offset ramp, and presented at ~75 dB. Sound frequency was 440 Hz or 460 Hz. White noise sounds and oddball tones was separated by a random inter trial interval of at least 30 s. All stimuli for each of the experiments were presented in one block. There is a marker for each sound onset (including standard tones) in the spike recordings. Participants where instructed to press a button when hearing any sound (SSNA_1) or an oddball (SSNA_2). These keystrokes where not recorded.本数据集包含7名健康未服药受试者（4名男性、3名女性，年龄23.7±4.0岁）在两种实验范式下的皮肤电反应（skin conductance response, SCR）与泌汗神经电图（sudomotor neurography）信号：其一为20段宽带白噪音刺激（记为SSNA_1），其二为Oddball任务（Oddball task）中的10个偏差音刺激（记为SSNA_2）。部分受试者未完成SSNA_2实验，或对SSNA_1进行了多次重复测试，最终SSNA_1共获得9条有效记录，SSNA_2共获得5条有效记录。SSNA_1范式下的白噪音刺激时长为1秒，起讫斜坡时长为10毫秒，呈现声压级约85分贝。SSNA_2范式下的偏差音与标准音刺激时长均为50毫秒，起讫斜坡时长为10毫秒，呈现声压级约75分贝，声音频率为440赫兹或460赫兹。每段白噪音或偏差音试次之间的间隔为随机时长，最短不低于30秒。两项实验的所有刺激均在单个实验区块内呈现。每条锋电位记录（spike recordings）中均包含对应每个声音起始时刻（包括标准音调）的标记。受试者被要求在听到任意声音（SSNA_1范式）或偏差音（SSNA_2范式）时按下按键，但该按键操作未被记录。
