> Renowned neuroscientist Alice Flaherty theorizes that the key biological ingredient in incubation is dopamine, the neurotransmitter released when we’re relaxed and comfortable. There are a lot of things attributed to dopamine these days, and it feels like it can't possibly be that simple. If it were, dopamine injections would be a great thing. It's kinda like brainwaves. Maybe it serves as a pretty good indicator (dopamine for 'pleasure', brainwaves for how relaxed you are) but it is simply small-minded to assume that dopamine alone is responsible for everything. Just like brainwaves aren't the end-all of psychology.
