Baby Brain Development Phases.
A fetus starts developing its brain from the replication of stem cells. All encompassing stem cells are unique, since they hold the power to develop into any cell that we are in need of in the body, like brain cells, heart cells or skin cells. Most brain neurons that are developing in the fetal phase will stay with us throughout our whole life, as opposed to any different cell in the body.
A fetus of a few weeks or a month is developing half a million brain neurons every 60 seconds! These developing brain neurons take their appropriate location in the brain by taking a hold of supporting types of cells referred to as glia cells. From 4 or so months and forward the neurons will begin establishing bonds to adjacent neurons. They work on this at a rate of two million bonds per second. This linking of the neurons adheres to a genetic plan, passed down from parents, and their predecessors.
At approximately the seventh or eighth month of fetal development the pruning gets going. In this time the brain will begin getting rid of lots of bonds, while fortifying others. This work seems to be to make sure that only the most useful survive, since the neurons that make up the first connection will last while the cells that were directed to create the same connection, but didn’t get the job done, will not have an effect. As with genetic evolution, only the strong survive.
At the end of pregnancy a kid’s brain is smaller than 1 lb, roughly 33% of the weight of the fully developed brain. Looking at a part of the brain no more significant than a rice grain, it holds roughly ten thousand neurons. As the baby is birthed the senses will begin developing, of which sight will be the last.
Of the whole development of the brain, eighty percent will take place since the end of pregnancy. Also, the pruning of bonds, will now take place from feedback from the outside world as opposed to just a genetic plan. Medical groups have discovered that when a baby receives immediate feedback connected to a movement to try something new, like producing a verbal sound, it will process speedier than when no information is taken in.
Following when the baby is out of the womb it will make use of approximately three quarters of the energy it eats for the development of the brain. This demonstrates why infants are usually asleep in these new stages, due to all of the nutrients they eat is used for the development of the brain and entire body.
