Ptafr deletion alters feeding and movement behaviors, but not energy metabolism monitored in a Comprehensive Lab Animal Monitoring System (CLAMS). Eight-week old WT and Ptafr^−/− mice with same body weight ingesting a CD were monitored for 2 days after a 2 day acclimation period and the following data were harvested. A. The respiratory exchange rate (RER). B. Accumulated food consumption over 24 h by individual WT and Ptafr^−/− animals. C. Ambulatory movement detected by interruption of an infrared beam in three dimensions over the stated interval. n = 3, *p < 0.05; #p < 0.01 Ptafr^−/− vs. WT mice. D. Rearing behavior monitored simultaneously as mentioned in panel C.
