Serotonin and Motivation for Food Intake = Sci’s New Hotness

This is a guest post in our #NPGsfn11 blog series and posted on behalf of Scicurious.

One of the interesting things that you get to see when you go to the Society for Neuroscience meeting is what’s up and coming, what’s hot, and what’s kind of fading from the forefront of the hivemind of neuroscience. As Sci walks around, seeing posters, hearing talks, seeing colleagues and friends, I hear words bandied around. Optogenetics is the new hotness. Oxytocin? A little last year.

And then there’s food and reward. It’s a quiet murmur, but it’s getting stronger. Things like “food addiction” and “sucrose reward” start to go around. And my ears perk up, because I personally find this subject FASCINATING. And you should, too. After all, there is a veritable symphony controlling what, and when, and how much you eat.

And to that symphony we can add the soft oboe modulating sound of the serotonin receptors in the nucleus accumbens.

Haihong Ye: Amazing changes in Chinese neuroscience over the past decade

[This is the inaugural post for a new feature at Action Potential. Periodically, we will provide insights from a regional correspondent on the interesting news, changes, or issues particularly affecting neuroscience in a particular location. Today’s post is from one of our Asian correspondents, Haihong Ye of the Institute for Biophysics in the Chinese Academy of Sciences. She reflects on the dramatic changes that have occurred within Chinese neuroscience during her decade-long absence from this now-flourishing community. We examined these issues in our March editorial, but now invite you to provide your opinion. – N.G.]

Over the past 10 years, especially the last five, the whole world has been amazed by the Chinese economy. To me, however, the improvement in biological science research in China is much more amazing. In the summer of 1998 I left Beijing and went to the US to pursue a Ph.D. in neuroscience. In 2007, after nine years of graduate study and post-doc training abroad, I came back to Beijing, seeking opportunities for further career development. What a difference some strong funding and visionary directives, not to mention a decade, can make.
