10  Streaming Brain

The stem cell is the atom of life with the capacity  to divide (procreate). Stem cell division initiates a  cell stream of its progeny.
Streaming tissues have four kinetic properties  which are shared by the brain:
1. Tissue proliferative unit TPU
2. Tissue functional unit TFU
3. Proliferon
4. A neoplastic  trajectory

Brain cells are born in the sub-ventricular layer and stream toward the cortex.
