Document Summary

Neurogenesis (by the time the infant is born, this is complete) and migration. They migrate in waves to certain area of the embryonic brain. They migrate and slowly develop axons and dendrites. Very limited in certain parts of brain (hippocampus) Learning is not related to number of neurons you have. Initially, there are not many but eventually synapses form many connections. Takes a long time for this to be finished. There"s many ways of connecting between point a and point b. Higher iq children have a longer period of synaptogenesis as well as synaptic pruning. Language areas (frontal/temporal areas), take the synaptogenesis at later point, peaks at. After conception, egg and sperm, fertilized egg, and then begins to divide. As a clump of cells and then in the womb. Each layer develops into something completely different in the body. The basic framework of your body (including muscles) Entoderm (respiratory tract) lungs, gastrointestinal tract, bits of urinary system.
