Scan Procedures and Parameters

Ethics approval: National Institutes of Mental Health Animal Care and Use Committee

Animal care and housing: National Institutes of Health Guide for the Care and Use of Laboratory Animals, Central Animal Facility at the NIMH

Any applicable training: Monkeys were trained to perform a fixation task, with a central fixation spot and complex visual objects.

Anesthesia procedures: Subject 32162 was lightly sedated with Diazepan (0.56 mg/kg, i.m.) before the anatomical scan and rest scans 7-10. All subjects were anesthetized with isoflurane before anatomical scans used for alignment of resting state data and for morphometric analysis.

Time between anesthesia and scanning: Rest scans were collected 13-48 minutes after Diazepan was administered.

Head fixation: For resting state scans, animals were head fixed using a non-metallic head post affixed dorsally to the skull using ceramic screws and acrylic.

Position in scanner and procedure used: For resting state scans, monkeys were oriented vertically in a sitting position.

Contrast agent: MION was administered (14-18 mg/kg, i.v.) before most resting state scans (excepting Subject 32162, Session 1, rest scans 1 and 2).

Physiological monitoring: One eye was monitored visually and gaze direction was recorded for periods when the eye was open.

Additional procedures: N/A

Scan sequences


The downloads consist of resting state, anatomical, and morphometric data from 3 subjects; three tables and a read_me files describing these data, and the NIMH Macaque Template (NMT) package.

Three tables describing the 3 subjects, 4 scan sessions, and 20 rest scans are included. Phenotypic Data describes the sex, age, weight, and species of each subject. Session Data describes those scanning parameters that remained fixed for an entire scan session (e.g. scan duration, TR, resolution) and the head coil used. Scan Data describes those things that changed across resting state scans, within a session. The read_me.txt file describes the naming scheme of the anatomical, resting state, and motion parameter files and what paper to reference when using this data.

The NMT package consists of the NIMH Macaque Template volume, segmentation masks, morphometric descriptions, surfaces, scripts for processing anatomical scans, and a read_me text file.
