The guy looks like a human being though.
If you're wondering how SSRIs and other drugs work, I present you picrel. The synapse has a gap in it where electrical signals bounce between then. When you flood the brain with Serotonin, it dampens the depression and anxiety signals.
That 'crash' after Cocaine or Ecstasy is because those are stimulants and force you to produce dopamine, and when your body is depleted of it, there is no Dopamine to block the signals for motivation, and you literally feel empty.
This is how chemicals in general affect mood.
Here is a more PhD level representation. The yellow circles are the Serotonin. You can literally control your thoughts via le drugs. Or some sort of imbalance caused by trauma.
