Serotonin Affects Behavior and Motivation

A long way of saying that living organisms need to enjoy their lives to properly function, cognitively and otherwise.

What a title, could just as well have been "major neurotransmitter affects brain function".

Then someone would complain "Why didn't they say it's a serotonin? That way title would be more informative".

it reads like the HN clickbait editor removed the "How" from it but in this case it's actually that the actual article is missing it.

The very first line contains a much better title:

> how activating the brain’s serotonin center affects behavior and motivation

Interesting study considering that a major field of anti-depressants has been working on the basis of this principle for decades

I couldn’t find in the text what exactly serotonin does. I assume it adds motivation?
