UW-Madison Rhesus MRI

The UW-Madison Rhesus MRI dataset includes anatomical, diffusion, and resting-state fMRI data from 592 macaque monkeys at two different sites. Subjects IDs start with "1" were acquired at site 1, subject IDs start with "2" were acquired at site 2.

Scan Procedures and Parameters

Ethics approval: Procedures were performed using protocols that were approved by the University of Wisconsin Institutional Animal Care and Use Committee in compliance with the Guide for the Care and Use of Laboratory Animals published by the US National Institutes of Health.

Animal care and housing: Monkeys were housed and cared for at the Wisconsin National Primate Research Center and the Harlow Center for Biological Psychology. Standard husbandry in a temperature- and humidity-controlled vivarium included a 12-h light/dark cycle, daily feeding sessions, ad libitum access to water, and daily enrichment.

Any applicable training: All study team members underwent extensive training to obtain proficiency in nonhuman primate handling, care, imaging, and anesthesia techniques. Animals did not undergo any training.

Scanning preparations

Anesthesia procedures: Monkeys were initially anesthetized using ketamine (15 mg/kg, IM), then given medetomidine (0.03 mg/kg, IM) or dexmedetomidine (0.015 mg/kg, IM). Additional doses of ketamine were administered as needed to maintain anesthesia. At the end of the procedure, atipamezole (0.15 mg/kg) was administered to reverse the medetomidine/dexmedetomidine.

Time between anesthesia and scanning: Scanning began approximately 30 minutes from first ketamine administration.

Head fixation: Monkeys were repositioned into a custom MRI compatible stereotaxic frame, which included ear bars and a tooth bar, that fit inside the MR coil.

Position in scanner and procedure used: Monkeys were scanned in the sphinx position with the nose pointing into the scanner.

During scanning

Physiological monitoring: Heart rate and oxygen saturation were monitored continuously and recorded at minimum every 15 minutes throughout the MR imaging procedure. Heated water bags, bottles, or pads and towels, blankets, and bubble wrap were used to maintain body temperature during imaging.
