Why This New Dopamine Study Has Scientists Rethinking Everything.

[00:00:00]So, I was going to a study published in science last year and it genuinely stopped me. Everything we thought we knew about dopamine, textbooks, the explainer videos, and all of it was based upon assumption that was actually never proven. Assumption was that dopamine floods the brain just like a broadcast signal, just like a chemical wave washing over a large area to influence our mood, our emotion, our behaviors. And this was what I was taught and this is what most of the people believe. But the researchers at the University of Colorado really used the advanced microscopy to watch moving through the brain in the real time. And what they found really overturned that model. Dopamine does not flood anything.

[00:00:38]It fires in concentrated hotspots. It's targeted, it's precise and accurate.

[00:00:43]Dopamine works like a postal service, not like a flood. And this really changes everything because the conditions like the ADHD, schizophrenia, depression are all linked to dopamine dysfunction. And every treatment that was ever built was based upon that flood model. But the fact that the molecule that is so important has been misunderstood for such a long time. And this tells how much we still have to learn.
