"in our experience, they're intertwined and inseparable, " berridge said . " in our brain, they are separable . " pecina and berridge made microinjections into rats " brains of drugs that stimulated receptors for opioids, or heroin-like substances, causing nearby neurons to activate particular genes that began producing proteins 研究過程中,派斯娜和貝利吉對(duì)老鼠的腦部進(jìn)行了藥物顯微注射,刺激老鼠腦部感受鎮(zhèn)靜物質(zhì)或類似嗎啡的物質(zhì)的受體,從而導(dǎo)致附近的神經(jīng)細(xì)胞刺激特殊的基因,并使其開始產(chǎn)生蛋白。
