A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

No, neurotransmitters don't work that way. It's like asking if capturing the energy from your house wifi's radio signals, and using it to charge your laptop, would cause your housemates' browser history to show up on your screen.
The popular conception of dopamine as reward/reinforcement is almost entirely incorrect. While your brain does use dopamine in reward-related signaling, it also uses it in aversion-related signaling, which is just the opposite. And also in motor coordination, which is why Parkinson's involves dopamine problems and is treated with dopamine-related drugs like levodopa. (And levodopa is not addictive, contrary to the popular conception of dopamine.)
