Human brain local field potential recordings during a battery of multilingual cognitive and eye-tracking tasks (Wrocław)

Intracranial human brain recordings from multiple implanted depth electrodes using stereo-EEG (sEEG) technology for seizure localization provide unique local field potential signals (LFP) sampled with standard macro- and special micro-electrode contacts. Over one hundred macro- and micro-contact LFP signals localized in particular brain regions were recorded from each sEEG monitoring case as patients engaged in an automated battery of verbal memory and non-verbal gaze movement tasks. Subject eye and vocal responses in both visual and auditory task versions were automatically detected in Polish, Czech, and Slovak languages with accurate timing of the correct and incorrect verbal responses using our web-based transcription tool. The behavioral events, LFP and pupillometric signals were synchronized and stored in a standard BIDS data structure with corresponding metadata. Each dataset contains recordings from at least one battery task performed over at least one day. The same set of 180 common nouns in the three languages was used across different battery tasks and recording days to enable the analysis of selective responses to specific word stimuli.This dataset contains only Uniwersytecki Szpital Kliniczny im. Jana Mikulicza-Radeckiego, Wrocław patients.

本数据集采用立体脑电图（stereo-EEG, sEEG）技术，通过多枚植入式深部电极采集颅内人脑电信号，用于癫痫病灶定位，可获取标准宏电极与特制微电极触点记录的独特局部场电位（local field potential, LFP）信号。
每一例立体脑电图监测病例中，当患者完成自动化语言记忆与非语言眼球运动任务组时，均可采集到分布于特定脑区的百余枚宏、微电极触点对应的局部场电位信号。针对波兰语、捷克语与斯洛伐克语版本的视觉、听觉任务，本研究通过自研网页转录工具精准检测受试者的眼球与发声反应，并准确标记正确与错误语言反应的发生时刻。
行为事件、局部场电位与瞳孔测量信号已完成同步，并存储于标准脑成像数据结构（Brain Imaging Data Structure, BIDS）及对应的元数据中。
每个数据集均包含至少1天内完成的至少1组任务的记录数据。
本次研究统一使用包含180个通用名词的多语言词表，覆盖不同任务组与记录天数，以实现对特定词汇刺激选择性反应的分析。
本数据集仅纳入弗罗茨瓦夫扬·米库利奇-拉杰茨基大学临床医院的受试者数据。
