fNIRS dataset recorded during real use of a cosmetic product

A dataset of 30 female participants (average age: 21.2, <i>SD</i>: 0.86, range 20-22), with 1 csv file of brain data per subject and 1 .pos file of registration data per subject Information regarding the triggers can be found in the "Trigger info.txt" file.<br>Brain hemodynamics were measured using the multichannel fNIRS system ETG-4000 (Hitachi Medical Corporation, Kashiwa, Japan), with two wavelengths of near-infrared light (695 and 830 nm). <br>Registration data was collected with a 3D digitizer system (ISOTRAK II, Polhemus Inc.)<br>Behavioral data, including the WTP data, can be found in "Behavioral data.xlsx".<br>The data was collected in the Applied Cognitive Neuroscience Laboratory in Chuo University, Bunkyo-ku, Tokyo during the first half of 2017 under the approval of the local ethics committees of both Chuo University and Shiseido Global Innovation Center. <br>

本数据集共纳入30名女性参与者，平均年龄21.2岁，标准差（SD）为0.86，年龄范围为20~22岁。每位受试者对应1份脑数据CSV文件与1份配准数据.pos文件。触发相关信息可参见"Trigger info.txt"文件。
脑血流动力学指标通过多通道功能性近红外光谱（functional near-infrared spectroscopy, fNIRS）系统ETG-4000（日本日立医疗株式会社，柏市）采集，实验采用两种波长的近红外光（695 nm与830 nm）。
配准数据通过3D数字化仪系统ISOTRAK II（Polhemus公司）采集获得。
行为学数据（包含支付意愿（Willingness to Pay, WTP）数据）可从"Behavioral data.xlsx"文件中获取。
本数据集于2017年上半年在东京都文京区中央大学应用认知神经科学实验室完成采集，相关实验流程已获得中央大学与资生堂全球创新中心的本地伦理委员会批准。
