title: Macaca mulatta and Macaca fascicularis anatomical and functional MRI data

description: The ION dataset includes anatomical, field map, and fMRI data from 8 monkeys: 4 <em>Macaca mulatta</em> and 4 <em>Macaca fascicularis.</em> The data is provided both as a directory structure compressed as <code>all_the_data.zip</code>, and as individual files. The correspondence between the directory structure and the individual files is contained in the file <code>tree.json</code>. The bash command <code>source unflatten.sh</code> can be used to convert the individual files into the original directory structure. <strong>Scanner Specifications</strong> Siemens Tim Trio 3T whole-body scanner with or without head-only gradient insert (Siemens AC88) 8-channel phased-array transceiver coils Optimization of the magnetic field prior to data acquisition: Manual shimming <strong>Sample Description</strong> Sample size: 8 Age distribution: 3.80-5.99 years Weight distribution: 5.0-10.2 kg Sex distribution: 7 male, 1 female Click here for the full sample description (.csv download) <strong>Scan Procedures and Parameters</strong> <em>Ethics approval:</em> All experimental procedures for nonhuman primate research were approved by the Institutional Animal Care and Use Committee in the Institute of Neuroscience and by the Biomedical Research Ethics Committee, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, and conformed to National Institutes of Health guidelines for the humane care and use of laboratory animals. <em>Animal care and housing:</em> Animals were housed in single cage <em>Any applicable training:</em> none <strong>Scanning preparations</strong> <em>Anesthesia procedures:</em> Anesthesia of the animals was inducted with an intramuscular injection of a cocktail of dexmedetomidine (18 - 30 µg/kg) and midazolam (0.2 - 0.3 mg/kg), supplemented with atropine sulfate (0.05 mg/kg). After intubation, anesthesia was maintained using the lowest possible concentration of isoflurane gas via a MRI-compatible ventilator. <em>Time between anesthesia and scanning:</em> Scanning lasted about 1.5 hours after induction. <em>Head fixation:</em> Custom-built MRI-compatible stereotaxic frame <em>Position in scanner and procedure used:</em> Sphinx position <em>Contrast agent:</em> none <strong>During scanning</strong> <em>Physiological monitoring:</em> Physiological parameters including blood oxygenation, ECG, rectal temperature, respiration rate and end-tidal CO<sub>2</sub> were monitored. Oxygen saturation was kept over 95%. <em>Additional procedures:</em> Animals were ventilated by a MRI-compatible ventilator. Body temperature was kept constant using hot water blanket. <strong>Scan sequences</strong> Resting-state: Gradient-echo EPI TR: 2000ms TE: 29ms Flip angle: 77° Field of view: 96 x 96 mm In plane resolution: 1.5 x 1.5 mm Slices number: 32 Slice thickness: 2.5mm GRAPPA factor: 2 Measurements: 200 Slice direction: Coronal slice Structural: T1 MPRAGE Sequence Voxel resolution: 0.5 x 0.5 x 0.5 mm TE: 3.12ms TR: 2500ms TI: 1100ms Flip angle: 9° Slice direction: 44 sagittal slices Number of averages: 2 Additional: Field map: a pair of gradient echo images TE1: 4.22ms TE2: 6.68ms Orientation and resolution: same as resting-state images Intended for EPI distortion correction <strong>Publications</strong> Lv, Q., Yang, L., Li, G., Wang, Z., Shen, Z., Yu, W., Jiang, Q., Hou, B., Pu, J., Hu, H., & Wang, Z.
