Document Summary

We need ultimately be able to transfer the newly developed neurons in a dish back into the brain, we might be able to repair the brain. * the brain has around 1011 neurons making around 1014 synaptic connections in the brain. * santiago ramon y cajal found it easier to study the young wood/developing brain rather than the impenetrable full grown forest/fully developed brain. * neural induction assigning neural potential to a region of early embryo. * neurulation forming the rudimentary nervous system. * morphogenesis and patterning of neural tube. * neurogenesis production of neurons and glia from precursor cells. * neuronal migration neurons move from sites of production to their positions in the mature brain. * axon growth and pathfinding to find appropriate targets and dendritic apoptosis arborisation. * synaptogenesis making and refining synaptic connections. * in the early developing embryo there are three primitive germ layers ectoderm, mesoderm & endoderm.
