The most potent protective factor , however , is a neurotransmitter called neuropeptide y ( npy ) , which binds to receptors on neurons in the prefrontal cortex and alters their response to noradrenaline , acting as a brake to its accelerator pedal .
In a study in the journal of cellular biochemistry , researchers at northwestern university 's feinberg school of medicine found high levels of a neuropeptide called " substance p , " or sp , in both fop patients and individuals who developed heterotopic ossification .
Conversely , flies that had been spurned whose neuropeptide f was increased boozed less .
相反地,那些被拒绝的雄性果蝇由于大脑中神经肽f的含量增多,酒的饮用量变少了。
Levels of neuropeptide y are lower in people who are depressed and have post-traumatic stress disorder .
忧伤或者是创伤后应激障碍的人,大脑中神经肽y的含量很低。
The researchers then lowered the amount of neuropeptide f in the brains of mated flies and found that they acted as though they had been rejected , drinking more .
Other possible and intriguing sources of nutritional effects on mood involve cholecystokinin ( cck ) , the most abundant neuropeptide in our cerebral cortex and limbic system .
