The more dendrites and synapses one has the greater the brain power and some experts believe that the gifted have denser connections. The question still not answered by the scientists: Are gifted children born with more dendrites and synapses or were they basically normal and it is the loving, learning environment they live in during their early lives that cause them to develop the connections so rapidly?
I have read the entire nature vs. nurture opinion thread from last spring. So interesting! The anecdotal stories, plus all the reading everyone has done to put their own situations in perspective is really very valuable to me.
We are in the process of adopting (WOO HOO! YIPPEE!) our second child.
Our firstborn came out of me, after a high risk pregnancy during which I wretched for 9 months, had to be hospitalized many times for it, and could never really walk or stand for very long during the pregnancy. So DD had little nutrition in utero and the only movement she was subjected to was the shaking of reverse parastalsys. She came into the world MAD, with the strongest neck and back you can imagine. She knew exactly who I was 3-4 days after birth (APGARS 4 and 8). She was only comforted by my holding her 24 hours a day and either nursing her, bouncing her on an exercise ball or letting her sleep/nurse in my arms. If I believed in reincarnation I would swear DD was reincarnated from a marsupial.
She had digestive issues and I did read others who said collicky babies who need to be bounced end up developing more wrinkles in their brains and go on to have more synaptic connections. (Sorry if I butchered that concept in my loose quote.) I've also read studies done on touch/neglect and brain development, and surely the fact that DD was on my person 24-7 qualifies her in the "high degree of touch" category, which may or may not contribute to her IQ. (I personally believe it is the touch aspect of breast feeding that impacts the breastfeeding-IQ relationship, so I also believe bottle feeding + touch can produce the same results. Just my humble opinion.)
So we just attended an Attachment Parenting workshop in preparation for adopting our 8 month old baby boy in a few weeks. Much of the material was on bonding, touch, and brain development. Neural development and synaptic connections are vastly improved with touch as well as response. All kinds of positive attention from a primary caretaker - singing, talking, feeding, holding, carrying, diapering, bathing, you name it - contribute to neural development. Having one caretaker who is always available to meet needs is very helpful for brain development too.
So I just wanted to add Attachment Parenting to this discussion, since our firstborn DD forced us into practicing it, despite our best intentions LOL, and our second child will be benefitting from it as well.
Incidently, his birthmother is a total resourceful survivor and this little baby who was born 2 months premature is already saying a few words and walking with his walker at 8 months. I think the birthmother, whose family is extremely dysfunctional and unsupportive, is quite bright and perhaps gifted.
