Typical records of core temperature (Tc, dotted line), tail skin temperature (Tsk, solid line) and ambient temperature (Ta dashed line) from three different Zucker lean rats at ambient temperatures of 27 °C (left), 29.5 °C (middle), or 32 °C (right). Note the large-amplitude fluctuations in tail skin temperature that occur at 29.5 °C, characteristic of tail skin vasomotion within the thermoneutral zone.
