This tube goes through neurulation, and this is the beginning of the development of the central nervous system.  After this forms, skin begins to form in sheets, and covers the entire body of the baby.  From there the hindbrain, midbrain and forebrain are formed.  ]]> 2018-08-30 02:52:48 UTC https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276463947 salvuccibella https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276463956 Even after a child is born, it's neurons are continuing to multiply. The growth and development of the child's brain is due to the formation of synapses, which are new formations and connections of neurons. Infants mentally take in a vast amount of information about the world around them, causing them to experience rapid growth after their postnatal time. ]]> 2018-08-30 02:52:51 UTC https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276463956 salvuccibella https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276799360 Nerve cells are then created, which are directly related to the creation of the brain. After the 5th week of gestation, the number of a child's neurons skyrocket. From here, glial cells stretch from the neural tube to help guide neurons to where they need to go. Lastly, the hindbrain, midbrain, cerebral cortex and forebrain are formed. ]]> 2018-08-31 03:18:23 UTC https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276799360 salvuccibella https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276799464 When babies come into this world, they carry with them far more neurons than they could utilize.  Neural Pruning is something that occurs during emerging childhood, and usually takes about twelve years.  This is when neurons die and many of the connections that have been made synaptically cease to exist.  It is believed that this overproduction of synapses occurs because it's nature's way of ensuring the baby has all they could need to develop properly. ]]> 2018-08-31 03:19:31 UTC https://padlet.com/salvuccibella/v65wc3gtoa4r/wish/276799464
