Radiotelemetric and HRV parameters in response to the saline injection test.

<p>Values are reported as means ± SEM of data obtained by averaging multiple 3-min segments acquired in baseline conditions (30 min) and following the injection of saline (60 min) in Fto^+/+ (n = 8) and Fto^−/− mice (n = 12). Abbreviations: HRV = heart rate variability; HR = heart rate; RMSSD = square root of the mean squared differences of successive RR intervals; HF = high-frequency; LF = low-frequency; T = body temperature; LOC = locomotor activity. * and ^# indicate a significant difference between Fto^+/+ and Fto^−/− mice (p&lt;0.05 and p&lt;0.01, respectively).
