如果要相信新的动物研究，血清素可能会做出更多的是调节我们的情绪和消化。据Zuckerman研究所的研究人员称，血清素可能会在吓人时踢到行动，帮助我们在我们的曲目中停下来分析潜在的威胁。
本文，最近发表在目前的生物学杂志，建议面对震惊的冻结是对受威胁和分析局势的根本反应。测量水果苍蝇走路的响应的实验发现，血清素负责导致这种反应。[1]
“Imagine sitting in your living room with your family and — all of a sudden — the lights go out, or the ground begins to shake,” said Richard Mann, Ph.D., a principal investigator at Columbia’s Mortimer B. Zuckerman Mind Brain Behavior Institute and the paper’s senior author. “Your response and that of your family will be the same: You will stop, freeze and then move to safety. With this study, we show in flies that a rapid release of the chemical serotonin in their nervous system drives that initial freeze. And because serotonin also exists in people, these findings shed light on what may be going on when we get startled as well.”[2]
使用Fronwalker跟踪果蝇的步骤，也称为果蝇。该装置是由哥伦比亚大学的研究团队开发的。血清素通常与情绪调节，抑郁，消化和肠道运动有关，也睡眠和骨骼健康。该研究发现，激素也可能在行走的规范中发挥重要作用。
