The dataset includes functional data from 2 monkeys.

- Scanner type: 3T horizontal bore scanner (Siemens Tim Trio) with head-only gradient insert (Siemens AC88)
- Coil: 8-channel phased array coil
- Optimization of the magnetic field prior to data acquisition: Shimming was used prior to the operation of the magnet to eliminate inhomogeneities in the magnetic field.
- Sample size: 2
- Age distribution: 4-6 years
- Weight distribution: 5-7 kg
- Sex distribution: both male
Scan Procedures and Parameters
Ethics approval: All experimental procedures conformed to US National Institutes of Health guidelines. The monkey protocol was approved by Caltech Institutional Animal Care and Use Committee (protocol # 1574).
Any applicable training: Monkeys were trained/rewarded for keeping their gaze within the screen window.
Anesthesia procedures: Monkeys were awake during scans.
Time between anesthesia and scanning: N/A
Head fixation: MRI-compatible plastic headpost
Position in scanner and procedure used: Sphinx position
Contrast agent: Exogenous MION-based contrast agent (Feraheme; 8-10 mg/kg IV)
- Naturalistic viewing:
- Voxel resolution: 1 x 1 x 1 mm
- TE: 16ms
- TR: 2000ms
- Flip angle: 90°
- Stimulus: Each monkey watched a complete movie (Baraka, 1992) in 10 functional runs (sound was not played). The first 3 and the last 7 TR of each run were blanks. The monkeys made free eye movements during the scans.
