As a cognitive scientist, I'm embarrassed at how long it took me to realise that emotion matters a lot, not just for understanding humans, but for understanding any thinking agent.

Why? Because emotion is an indicator of what that agent values, and values are essential to rationality.

Examples:

There's much talk these days about what's required for "real" intelligence, such as world models and the like. One thing we know about the human evolution of it: it required/requires emotion. That may have been better appreciated in 1938 than today.

Subtract the emotional element from religion, literature, and art and there would be left the merest dross, an utterly meaningless mass of symbols and responses. Emotionless, man could not produce poetry, music, the graphic arts, or any of the splendid products of a refined culture. The generous sweeps of the imagination that have brought forth romantic movements in the world^s history, the noble aspirations of the intellect that have led whole peoples to seek a higher life, the tremendous activities of organized groups which have spread the best tokens of their civilizations to other lands, the splendid achievements of individual pioneers, adventurers, craftsmen, artisans, composers, inventors, scientists, and spiritual leaders, would never have come to pass in an emotionless world.

It's no wonder Mr. Freeze turned to a life of crime to fund his research.

I don't think you non-science people realize what it takes to get a grant funded by NIH. Started experiments in Sept 2021 to generate 3 new mouse mutants to model human disease. Prelim dara shows they have relevant disease phenotypes worthy of study. Need a small grant first to characterize /1

A paper in Nature Communications shows that there are five phases of brain rewiring across the lifespan. The eras of childhood, adolescence, adulthood, early aging, and late aging each have characteristic rewiring of structural connections across the whole brain. go.nature.com/44DLkxE 🧪
This is figure 5, which shows topological changes within the five topological epochs of life.
