Emotional reactivity modulates autonomic responses to an acoustic challenge in quail. Physio Behav 00(0) 000-000, 2006. This study investigated the relationship between emotional reactivity and behavioral and autonomic responses to an acoustic stimulus in quail. It was hypothesized that birds with high emotional reactivity would have higher motor inhibition combined with higher sympathetic activation than birds with low emotional reactivity. Two experiments were performed. The first looked for correlations between emotional reactivity, evaluated by a tonic immobility test, and motor and Heart Rate Variability in relation to an acoustic stimulus. The second experiment compared the motor and autonomic responses to the acoustic stimulus of quail selected on either long (LTI) or short (STI) duration of tonic immobility. The first experiment showed that the acoustic stimulation induced motor inhibition and cardiac activation. Correlations were found between tonic immobility duration and both autonomic activity before stimulation and sympathovagal balance after stimulation. In the second experiment, LTI quail showed strong sympathetic activation, whereas STI quail showed parasympathetic and sympathetic activation. The activation of the parasympathetic system induced by the noise in STI quail can be explained by the predominance of this system at rest in this line. In conclusion, both the basal autonomic activity and the autonomic responses differed according to the emotional reactivity, and changes in autonomic activity appear to be related to the genetic selection process.
情绪反应性调节鹌鹑对声学刺激的自主反应。《生理与行为》00(0) 000 - 000，2006年。本研究调查了鹌鹑的情绪反应性与对声学刺激的行为和自主反应之间的关系。研究假设为，与情绪反应性低的鸟类相比，情绪反应性高的鸟类具有更高的运动抑制以及更高的交感神经激活。进行了两项实验。第一项实验寻找通过强直性静止试验评估的情绪反应性与声学刺激相关的运动和心率变异性之间的相关性。第二项实验比较了在强直性静止时长方面被选出来的长时（LTI）或短时（STI）鹌鹑对声学刺激的运动和自主反应。第一项实验表明，声学刺激诱发了运动抑制和心脏激活。在强直性静止时长与刺激前的自主活动以及刺激后的交感迷走神经平衡之间均发现了相关性。在第二项实验中，长时鹌鹑表现出强烈的交感神经激活，而短时鹌鹑表现出副交感神经和交感神经激活。短时鹌鹑中噪声诱发的副交感神经系统激活可以通过该品系中该系统在静息时占主导地位来解释。总之，基础自主活动和自主反应均因情绪反应性而不同，自主活动的变化似乎与基因选择过程有关。
