Watching pornography may shrink the brain and dull responses to sexual stimulation, researchers have suggested. Scientists have found for the first time that regularly viewing sexual images could be physically harmful. Researchers from the Max Planck Institute in Berlin found that a part of the brain which activates when people feel motivated or rewarded, shrinks and works less efficiently. So people who watch a lot of porn are likely to need increasingly graphic material to achieve the same sexual stimulation. For the study, Dr Kuhn and her colleague Jurgen Gallinat from Charite University, also in Berlin, recruited 64 healthy men between the ages of 21 and 45 years and asked them questions about their porn-watching habits. They also took images of the men’s brains to measure volume and to see how their brains reacted to pornographic pictures. They found noticeable differences in the men who abstained compared with those who regularly accessed sexual videos or images. However other researchers claimed that pornography in moderation was probably not damaging. “Everything is going to be bad in excess and it’s probably not terrible in moderation,” Dr Gregory Tau of the Columbia University Dr Tau, who was not involved with the study, agreed that more research should be done in this area and that longer studies would be need to find out if porn leads to brain changes. “It is possible that there are individuals with a certain kind of brain that are more susceptible to these kinds of behaviors,” he said. The study was published in JAMA Psychiatry. |
據(jù)《每日電訊報》報道,調(diào)查顯示觀看色情電影可能使大腦收縮,并對性刺激反應(yīng)遲鈍。 科學(xué)家首次發(fā)現(xiàn),定期地觀看性圖片會對生理有損害。 柏林馬普研究所的調(diào)查者發(fā)現(xiàn),當(dāng)人們感到激動或者受到獎賞時,腦的一部分運動會收縮并且效率低下。 所以看過很多色情音頻視頻的人很容易需要比原來更多的形象的感官刺激來達到同樣的性刺激。 研究中,庫恩博士和他來自柏林查理特大學(xué)的同事尤根,征集了64位年紀在21到45歲的健康男士,問他們關(guān)于觀看色情片的問題。 他們還給這些人的大腦拍了照片,測量大腦容量,觀察大腦受到色情圖片刺激時的反應(yīng)。 同經(jīng)常定期地看色情影像的男人比,在擁有自制力的人身上,他們看到了顯著的差別。 然而,有一些調(diào)查者聲稱有節(jié)制的觀看色情影像不會對大腦產(chǎn)生損害。 “任何事過度的做都是有害的,有節(jié)制地做可能不算太糟,”哥倫比亞大學(xué)的格雷戈里博士說。 格雷戈里博士沒有參與這項調(diào)查,他認為為了以后能夠證明色情損害大腦應(yīng)該做更多的調(diào)查。 “可能存在天生對這些東西敏感的大腦,”他說。 這項研究發(fā)表在《美國醫(yī)學(xué)會雜志—精神病學(xué)》上。 (譯者 fsy1991 編輯 王輝) 掃一掃,關(guān)注微博微信
