Document Summary

Neural proliferation: once the lips of the neural groove have fused to create the neural tube, the cells of the tube begin to proliferate (increase greatly in #) Radial glia cells: a temporary network of glial cells. Aggregation: developing neurons align themselves with other developing neurons that have migrated to the same area to form the structures of the nervous system: cams: located on the surfaces of neurons and other cells. Growth cone: at each growing tip on an axon or dendrite is an amoeba-like structure. Roger sperry"s experiment (there is an mpl that explains this experiment) Chemoaffinity hypothesis: sperry: each postsynaptic surface in the nervous system releases a specific chemical label and that each growing axon is attracted by the label to its postsynaptic target during both neural development and regeneration. In other words, growing axon does not grow at random!!! Pioneer growth cones: first growth cones to travel along a particular route in a developing nervous system.
