How Does the Brain Work?
... The brain is a multilayered web of cells: nerve cells (neurons) and vastly more numerous glial cells that stabilize the chemical environment and regulate and protect neurons. The outermost layer, the cerebral cortex, is a fraction of an inch thick but contains 70 percent of all neurons. This most ev ...
