Fact-BUZZ Friday; Emotions
Various parts of the brain work together to control emotion.. not only the feelings you feel, but the response to those feelings as well. Let me start by reminding you all that I'm not a medical professional whatsoever... the information here is a pool of information I've read and there are always differing ideas and concepts, including information which is completely opposite of what I may write here. I'll try to keep the details vague so it simply gives you a general idea of what is what and it's job... in reality, no one knows for sure which parts of the brain do what or how they function. If you question that notion, explain how a child with an empty MRI scan can live a quality life for many years (hydranencephaly dispels many medical theories & textbook definitions).
So, here's the brain from the outside:

Inside of those parts that you see above is the limbic system, deep in the center (actually inside the brain you see above is two more "brains" but I'll refrain from confusing the issue further and stick with the basics). It actually may be intact in children with hydranencephaly (it's hard to say for sure since the brain is such a complex, complicated organ to map) and my theory is that both "inner" brains are oftentimes fully intact and functional, aside from some more severe cases of hydranencephaly where greater damage is apparent through lacking cerebellum or brain stem malformation. Back to the topic: that is the area thought to control an individual's emotional state. Around the deep limbic system is the basal ganglia, which controls emotional response... when you jump in response to startle, cry when you're sad, laugh when something is funny, you get the picture. Our kids don't always display a correct response to stimulations, but they oftentimes do... other times it may be an exaggerated response, especially apparent with the startle reflex often mistaken for seizures!

The area to the left, which is actually the front of the brain, is the frontal lobe. This part is generally non-existent in hydrancephalic children. This part's job in the realm of emotion is to control response to emotion... since this is most absent in children with hydranencephaly, it could explain why many parents report their children laughing inappropriately at say... babies crying! I'm not an expert, only done extensive research, but it's a thought. Between the frontal lobes is the ACG, which controls how "easy-going" your emotions are. Since many children are pretty laid back but not really keen on changing things up or a mess in schedule, the absence of this part may prevent control over level-headed emotions.
Those temporal lobes are located behind the ear area, and are responsible for recognition of objects and emotional stability. Some kids have a keen sense of object recognition, others not so much... but MOST do recognize their surroundings and the people they love over strangers. Their response may not be that of a typical child, but they clearly display a difference in emotion on their own level. Example: Brayden would become extremely rigid and his breathing would speed up if held by someone he wasn't familiar with... also, if a stranger patted his hand, even lovingly to say hello, he would yank his hand back and yell at them!
“Everybody is a genius.
But if you judge a fish by its ability to climb a tree,
it will live its whole life believing that it is stupid.”
Those of you who have a little "bee" in your life know very well how emotional they can be... they laugh, they cry, the smile, they "talk", they speak their emotions through their body language... as far as not showing emotion, FICTION!
