The process was discovered during Rolls's studies aimed at deciphering the inner workings of dendrites -- the part of the neuron that receives information from other cells and from the outside world. The research will be published in the print edition of the scientific journal Current Biology on 21 December 2010.
The other cells, neurons, act as the communicators of the nervous system. Neurons receive information, integrate it, and pass it along. They communicate with one another, with cells in the sensory organs, and with muscles and glands. Each neuron has the same structure:1  Each neuron has a soma, or cell body, which is the central area of the neuron.2  It contains the nucleus and other structures common to all cells in the body, such as mitochondria. Axons send information to other neurons, to muscle cells, or to gland cells. 2  What we call nerves are bundles of axons coming from many neurons. 3  Some of these axons have a coating called the myelin sheath. 4  Glial cells produce myelin, which is a fatty substance that protects the nerves.
