“…Cutaneous vasodilatation of the tail can be monitored by measuring several different parameters, including tail skin temperature. A variety of instruments can be used to monitor tail skin temperature: infrared thermography (Almeida et al, 2006a; Garami et al, 2011; Ikeda et al, 2008), temperature-sensitive dyes (Romanovsky et al, 2002), thermocouples attached to the surface of the tail (Dacks and Rance, 2010; Hosono et al, 2001; Romanovsky et al, 2002) or implanted subcutaneously (Szélenyi et al, 1992), telemetry probes or Subque dataloggers mounted on the surface of the tail (Gordon et al, 2002; Williams et al, 2010), or surgically implanted telemetry probes with sensor leads tunneled to the base of the tail (Berendsen et al, 2001; Bowe et al, 2006; Cosmi et al, 2009). …”
