Triune Brain
Not rigorous enough for pure neuroscience. But rigorous enough for people to grasp the brain?
The actual reality is complex and gritty. Yet we don't explain the reality of quantum physics- we present simple, understandble analogies for people to grasp.
My question to neuroscientists here. Can this be used as a basic explanation of our brain function? As far as I can tell the limbic system exists in many mammals yet not in reptiles. And the neocortex is grossly enlarged in humans.
Wikipedia doesn't have any good articles on brain evolution and I'm looking for a model to elegantly explain brain evolution from primitive amniotes. The triune brain offers me this and is it terribly invalid for me to say:
> R-complex in early tetrapods
Fear, aggression, violence. Instinctual
> Limbic system greatly enlarged in early mammals
Emotion, empathy, love
> Neocortex, massively expanded in early apes
Logic. Foresight. And reason.
?
How about birds? Early amniotes -> therapsids -> mammals. OR amniotes -> archosaurs -> birds. Yet birds have a well developed Neocortex. This structure must have been present in primitive amniotes. Were they just very small and later expanded?
Thanks
