Document Summary
Prenatal brain development video from youtube the species look similar early on in their development and begin to look more like their individual species as they continue to develop. Basic life functions are taken care of by the hindbrain. Neural plate is a thickened region that begins to form a groove down the middle (early stages of ventricular system and where neurons and glial cells will proliferate from) Day 100 we have a overlapping cerebral cortex, the shape and orientation of the spinal cord is clear. Stem cell: cells that are undifferentiated: neural stem cells can divide where one half doesn"t survive, the half that does survive turns into a progenitor cell. Progenitor cell can be differentiated into a neuroblast or a glioblast. Neurons and glial cells were all created from the same stem cell dna or gene: the process of different chemicals and hormones in time with interactions with other cells allow these cells to differentiate.
