Data from: Twist and chew: three dimensional tongue kinematics during chewing in macaque primates

These data were collected using the University of Chicago XROMM Facility. All procedures were approved by the University of Chicago IACUC. Four adult rhesus macaques (Macaca mulatta) were observed in this study (Table 1). The animals were housed in an AAALAC-accredited animal facility, fed monkey biscuits and given daily enrichment. They were trained to feed while restrained in a radiolucent, acrylic primate chair. Monkeys C and H were trained to feed with their heads restrained, facilitating marker tracking, shortening recording durations, and reducing radiation exposure. The monkeys were fed red grapes (10-20 mm) and biplanar videoradiographic data were collected (technique: 90–100 kVp, 10–16 mA, 200 Hz, and with a 2–4 ms shutter speed). Data were processed using the XROMM workflow and custom R scripts. Analyses were conducted using custom R scripts, included here.
