Left handedness

I think to myself, jokingly of course, that it must be true that I am dominant in only one side of my brain (I must be using only half my brain!)  I cannot seem to wrap my head around the concept lateralization and contralateral control, it confuses me so much!  I think the most important thing I learned was that even though the hemispheres of the brain specialize in different operations, they communicate through the corpus collosum and through small commissures and that you use BOTH hemispheres and require cooperation from both sides.

My mother, my husband, and my son are all lefties.  The hemispheric dominance has been pretty interesting to me and I noticed something during my reading that I wouldn't have paid such close attention if it didn't pertain to someone in my life.  Speech, my husband had a stutter when he was a young boy.  He doesn't really stutter anymore but if he's trying to say something really fast or if I feel like he's got a rush of information that he just wants to let out I can hear it.  I read that most left-handers have a left- hemisphere dominance for speech but some might have right hemisphere dominance or a mixture of both and many people who have bilateral control of speech stutter.  I'm not a neuroscientist, but I'm assuming he might have bilateral control of his speech.  Maybe or maybe not? Either way, it was interesting to learn about.  

Here's some debunked rumors about lefties that I found very interesting:
