Talk:Evolution of emotion
|WikiProject Neuroscience||(Rated Start-class, Mid-importance)|
This page focuses on the universality of emotion, but doesn't speak of other aspects of the evolution of emotion, such as how and why emotion might have evolved, what purpose it played and whether/how it lent a selective advantage. (Tczuel (talk) 04:32, 4 May 2009 (UTC))
I think this para' needs work. I'll have a look at it when I can, but please have a go if you're interested and have time.
- Joseph LeDoux focused much of his research on the emotion of fear. He offered the example of becoming fearful of a snake, when the snake is actually a stick. Fear can take two routes in the brain, one direct, the other much less direct. The less direct route being the most recently evolved. With a path moving through the neocortex and finally to the amygdala, it is a process that could only happen after the formation of the "new" brain. The faster response (thalamus to amygdala) may make the difference between surviving and passing on genes.
