资源简介：
Two adult rhesus macaques (Macaca mulatta; one male, one female; age: 12 years; weight: 7-11 kgs)
were acclimated over three weeks to head-fixation and the MRI environment using a mock scanner.
They were trained to sit in a sphinx position in an MRI-compatible chair (Rogue Research) and
fixate on a central cross. Scanning took place in a horizontal 3T MRI scanner (Siemens Prisma),
with alternating runs of resting-state (~13 min; blank screen with fixation cross) and
naturalistic viewing (3 videos/session, 8 min each; Monkey World documentaries). Eye movements
were tracked at 1000 Hz using an Eyelink 1000 Plus system. Each monkey completed six sessions
across six days, viewing nine unique videos twice. Calibration was performed using a five-point
fixation grid, and behavior was monitored using Presentation® software. Visual stimuli were
projected (CHRISTIE LX501), and rewards were delivered via a computer-controlled system (Crist®).
Each session lasted 2–3 hours. The dataset is structured according to BIDS standards, ensuring
broad reusability for research on primate neuroimaging and visual cognition.
