The circadian rhythms of hypothalamic norepinephrine (NE) and of circulating norepinephrine, epinephrine (E), corticosterone, aldosterone, and serotonin (5HT) were determined in group-housed and in individually housed male adult rats, adapted to a 12/12 light/dark cycle. After 5 weeks of individual housing, compared to group-housed animals, hypothalamic NE mesor decreased, while circulating NE, E, and corticosterone mesor increased. The circadian rhythms of aldosterone and 5HT were unaffected by individual housing.
在适应12/12光/暗周期的群居和独居成年雄性大鼠中，测定了下丘脑去甲肾上腺素（NE）以及循环中的去甲肾上腺素、肾上腺素（E）、皮质酮、醛固酮和血清素（5HT）的昼夜节律。在独居5周后，与群居动物相比，下丘脑NE的中值降低，而循环中的NE、E和皮质酮的中值增加。醛固酮和5HT的昼夜节律不受独居的影响。
