Dopamine doesn’t flood the brain as once believed – it fires in exact, ultra-fast bursts that target specific neurons. The discovery turns a century-old view of dopamine on its head and could transform how we treat everything from attention-deficit/hyperactivity disorder (ADHD) to Parkinson’s…
As stated in the other post, this article mischaracterizes the findings. No one thought dopamine flooded the brain. This finding is important because it’s the first time we’ve been able to visually see the behavior we thought was happening.
Thank you. Almost every word of the sentence above is very much not what college freshmen have been taught for 30+ years. Dopamine was never thought to “flood the brain.” For a few decades it’s been understood to have highly targeted action, restricted by various factors not least of which is the fact that dopamine is only produced in/near certain synapses.
