  • All data are mean ± SEM (number of mice). rMSSD, Root mean square of successive differences in heart period, a measure of heart-rate variability; NE, plasma norepinephrine concentration. *p<0.0001 compared with control mice (Wilcoxon rank sum test).

  • a Except for body weight, data are from experimental days 2-7.

  • b Data are from EAAN mice examined on experimental days 14-27.

  • c Data are from all mice except those killed before experimental day 3.
