Document Summary

Preformation: proposed by early philosophers; the idea that fetal development was merely an enlargement process of a miniaturized organisms. Today, we know that brain development begins in a curled sheet of cells called the neural tube, which proliferates neural stem cells. Stem cells progenitor cells neuroblasts/glioblasts specialized cells. Both genetic and neurotrophic chemical factors inluence cell specialization. Neurotrophic factor: a chemicalcompound that acts to support growth and diferentiation in developing neurons and may act to keep certain neurons alive in adulthood; signal cells to develop in particular ways. Epidermal growth factor (egf) stimulates stem cells to produce progenitor cells. Basic fibroblast growth factor (bfgf or fgf-2) stimulates progenitor cells to produce neuroblasts and glioblasts. Cell birth cell migration cell diferentiation synaptogenesis cell death/synaptic pruning . Radial glial cell: path-making cell that a migrating neuron follows to its appropriate destination within the cortex. Cell-adhesion molecules (cams) provide a surface to which growth cones can.
