抱怨女性想太多?美国研究显示男女有别 女性大脑更活跃

2017-08-09 07:45:16   新华网

人们常常听到男女吵架时,男方抱怨女人想太多了。美国一项最新研究发现,想太多这件事还真不怪女人,这都是男女大脑中先天存在的区别“惹的祸”。

据英国《每日邮报》8月7日报道,美国加利福尼亚州阿门诊所的研究人员对超过4.5万份研究进行分析,发现女性之所以对事情考虑过多,是因为女性大脑比男性大脑要活跃得多。这次研究的对象包括119名身体健康的志愿者及26683名患有精神类疾病的患者。

研究结果显示,女性大脑内多处的血流速度要高于男性,这能够增加她们对事物的专注度以及同情心,与此同时女性也更容易感到焦虑。

研究人员表示,这一发现可以合理解释并解决夫妻吵架的一些问题。此外,研究结果或可说明,为什么阿兹海默症、抑郁症及焦虑症等疾病中女性发病率更高,而男性则更易患有多动症及其他与行为相关的疾病。

研究显示,女性大脑比男性更为活跃,尤其在前额皮质和边缘系统这两个区域。前额皮质与注意力和冲动控制力有关,而边缘系统则与心情和焦虑感有关。此外,男性大脑内也有些区域比女性反应更活跃,主要表现在大脑内的视觉中心和协调中心。

这一研究可以很好地说明,为何女性在同情心、直觉、协作能力、自我控制力以及适当关注力方面具备更大的优势;同时也可以解释女性为何更易出现焦虑、抑郁、失眠以及饮食失调等症状。

研究者对9个诊所提供的有关单光子发射计算机断层扫描(SPECT)的成像研究进行了深入分析。SPECT可以测量大脑中血液的流动。阿门诊所的创始人、这次研究的主要作者丹尼尔·G·阿门表示:“这是一项非常重要的研究,能够帮助我们了解不同性别的大脑差异。”

“我们在男性和女性大脑中发现的可量化的区别,有助于了解不同性别发生阿兹海默症等大脑疾病的风险。使用如SPECT等功能性神经影像学工具,对于未来研发针对大脑疾病的精准治疗方法至关重要,”丹尼尔·G·阿门说道。(孙若男)
