The Neuroanatomy of Crying

Of course animals or any creature with eyeballs if it's irritated will produce tears. But we homosapiens, humans cry emotionally and crying emotionally I believe is one of the distinctive features of being human. And so part of the book why humans like to cry was pulling out the neuroanatomy that linked certain areas in the brain loosely you can describe areas like limbic structures and cortical structures but also what is most relevant is the descending pathways from the higher areas of the brain down into the brainstem where from the brainstem there are fibers which go out of the brainstem exactly to the nuclei that lead to tearing.
