From Sleep Study, Clues to Happiness.

From the NY Times...hypocretin is a new one on me!

I am just not sure about all this tinkering with the brain with drugs when we really know so little about how all the pieces fit together.

Now research shows that in addition to regulating sleep, hypocretin also appears to govern emotion, particularly experiences of joy and happiness.

The study has implications that extend beyond narcolepsy. It suggests that the brain has several different arousal systems, and that one of them, driven by hypocretin, has the specific function of keeping people awake for pleasure.

It also raises concerns that drugs that block hypocretin could potentially cause depression and other unexpected side effects. One such medication, a sleeping pill from Merck called suvorexant that works by blocking hypocretin, essentially causing narcolepsy for a night, is awaiting government approval.
