Pediatric epilepsy surgery visual category evoked BOLD fMRI dataset

Participants: five pediatric patients with resections to the visual cortex, two patients with resections outside the visual cortex, two patients with left hemispherectomy, and nine age-matched typically-developing controls.Most images were acquired on a Siemens Verio 3T scanner with a 32-channel head coil at Carnegie Mellon University, except for one participant (JF) whose data were acquired on a Siemens Prisma 3T scanner with a 64-channel head coil.For all participants: a skull-stripped T1-weighted anatomical image and three sets of visual category localizer BOLD signal are included here, as well as the sequence timing files for the order of presentation of the visual categories.See Maallo et al, "Large-scale resculpting of cortical circuits in children after surgical resection" Scientific Reports (in press)Sample code to compute the significant correaltion fraction (SCF) is included.

研究对象：5名接受视觉皮层切除术的儿科患者、2名接受非视觉皮层切除术的患者、2名接受左侧大脑半球切除术的患者，以及9名年龄匹配的典型发育对照组受试者。大部分影像数据由卡内基梅隆大学的西门子（Siemens）Verio 3T磁共振扫描仪配合32通道头部线圈采集，仅1名受试者（JF）的数据采用西门子（Siemens）Prisma 3T扫描仪及64通道头部线圈采集。所有受试者的数据集均包含去颅骨T1加权解剖影像、3组视觉类别定位血氧水平依赖（Blood Oxygen Level Dependent, BOLD）功能磁共振信号，以及视觉类别刺激呈现顺序的序列时序文件。详见Maallo等人发表于《Scientific Reports》（已接收待刊）的论文"Large-scale resculpting of cortical circuits in children after surgical resection"。本数据集附带用于计算显著相关分数（Significant Correlation Fraction, SCF）的示例代码。
