Resting state fMRI data from n=14 mice under medetomidine-isoflurane anesthesia (0.05 mg/kg bolus and 0.1 mg/kg/h IV infusion, plus 0.5% isoflurane) from Gutierrez-Barragan et al. 2021 (DOI pending). Scans were acquired at the IIT laboratory in Rovereto (Italy) on a 7.0 Tesla MRI scanner (Bruker Biospin, Ettlingen) with a BGA-9 gradient set, a 72 mm birdcage transmit coil, and a three-channel solenoid receive coil. Awake scans used a single-shot echo planar imaging (EPI) sequence with the following parameters: TR/TE=1000/15 ms, flip angle=60°, matrix=100 x 100, FOV=2.3 x 2.3 cm, 18 coronal slices (voxel-size 230 x 230 x 600 µm), slice thickness=600 µm and 1920 time points, for a total time of 32 minutes. It is suggested to remove the first 120 scans (2 minutes) to account for thermal gradient equilibration.本数据集包含Gutierrez-Barragan等人2021年研究（DOI待公开）中n=14只经美托咪啶-异氟烷麻醉的小鼠的静息态功能磁共振成像（functional Magnetic Resonance Imaging，fMRI）数据，麻醉方案为0.05 mg/kg团注联合0.1 mg/kg/h静脉输注，辅以0.5%异氟烷。扫描采集于意大利罗韦雷托的IIT实验室，采用7.0特斯拉磁共振扫描仪（布鲁克生物自旋公司，埃特林根），配套BGA-9型梯度线圈组、72 mm鸟笼式发射线圈以及三通道螺线管接收线圈。清醒状态下的扫描采用单次激发回波平面成像（echo planar imaging，EPI）序列，参数设置如下：TR/TE=1000/15 ms，翻转角=60°，矩阵=100×100，视野（field of view，FOV）=2.3×2.3 cm，18层冠状位切片，体素尺寸为230×230×600 µm，层厚600 µm，共采集1920个时间点，总扫描时长32分钟。建议去除前120帧扫描图像（对应2分钟时长）以校正热梯度平衡效应。
