Scan Procedures and Parameters

Ethics approval: UC-Davis IACUC

Animal care and housing: CNPRC is staffed with 7 full-time veterinarians and an extensive staff of veterinary and husbandry technicians. Monkeys were housed in pairs (N=16) or singly (N=4) indoors in standard primate caging, in housing rooms containing other rhesus monkeys. Single-housed monkeys had failed repeated attempts to find compatible cage mates from elsewhere in the colony. All monkeys received environmental enrichment consisting of toys and novel food items.

Any applicable training: none prior to MRI scanning

Scanning preparations

Anesthesia procedures: ketamine, dexmedetomidine, buprenorphine prior to intubation and placement in stereotaxic frame; isoflurane maintenance anesthesia (1-2%, to effect)

Time between anesthesia and scanning: Monkeys were placed in the scanner as soon as isoflurane anesthesia was initiated and stable

Head fixation: Monkeys were placed in an MRI-compatible stereotaxic frame (Kopf)

Position in scanner and procedure used: Sphinx position head first (recorded as head first prone in scanner; note that header info have been corrected to reflect anatomy)

Contrast agent: none

During scanning

Physiological monitoring: pulse rate, SpO₂, end tidal CO₂, inspired/expired isoflurane, blood pressure

Additional procedures: artificial ventilation to maintain normocapnia, normothermia maintained by heated air blanket
