How Nerve Cells Grow:
Göttingen-based Max Planck researcher decodes a molecular process that controls the growth of nerve cells
“In order to be able to receive signals from other cells, nerve cells form complex extensions called dendrites (from the Greek `dendron' meaning tree). The growth of dendrites in the human brain takes place mainly during late embryonic and infantile brain development. During this phase, dendrites, with a total length of many hundred kilometres, grow from the 100 billion nerve cells in our brain. The result is a highly-complex network of nerve cells that controls all bodily functions - from breathing to complicated learning processes.
In order that this incredible growth phase of brain development does not lead to chaos, the growth of the dendrites must be accurately controlled. (italics – nrp) In fact, a large number of signal processes control the direction and the speed of dendrite growth by influencing the structure of the cytoskeleton, which is inside the growing dendrite and responsible for its shape and extension.”
