By [http://ezinearticles.com/?expert=K._Kemper] K. Kemper "A simplified description of the operation of a neuron is that it processes the electric currents which arrive on its dendrites and transmits the resulting electrical currents to other connected neurons using its axon. A simple explanation of the processing step is that the cell sums up the incoming signals and produces an output signal only if this sum exceeds some threshold; i.e. only if the total input signal is big enough will the cell `fire' an output signal to its neighbors. The pulse reaches the end of the axon branch and causes the release of certain chemicals called neurotransmitters. These diffuse across the synaptic gap (a distance of some one-hundredth of a micron) to be picked up by so-called receptors on the ends of the dendrites of a neighbor neuron. This absorption process on the new cell changes its electrical state. If there are sufficient incoming signals to this neighbor neuron, this change in its electrical state can be big enough to generate a new pulse in the neuron. Thus the process repeats in this new cell. This cell is itself connected to many others and in this way a wave of electrical activity can be set up. Different types of brain activity correspond to different patterns of firings." http://brain.web-us.com/brain/bio_org.html Thus, we have an abbreviated description/statement of how the brain works on the mechanical-electrical level. Let's now ponder headaches-are headaches caused by shorts in the synaptic gaps? Or because too many "Firings" are occurring concurrently? Our world-wide physicians, both general and neuro, agree that they know little about the brain when comparing this organ to others in the body. Test patients/experimenters often wear crazy hats or electrodes attached to the scalp or forehead and then those wires connected to myriad test equipment to test also, a myriad of dysfunctions, or physical aberrations. We also know in all county hospitals and other specific hospitals around the world, are patients suffering from various forms of mental illness. I wonder if in fact that some of these illnesses stem from shorts in their synapses-if perhaps the patients are not totally "Bonkers" but instead, perhaps have filters filtering out "Normal" daily sounds and actions and perspectives and instead, hearing the filtered material instead of having it filtered and not hearing normal animal, mechanical and human sounds Once the cell fires, an electrical signal travels down the axon at a speed of around 100 meters per second (200 mph). These currents are very small by usual standards. The typical voltage difference between the outside and inside of a nerve cell is 70 millivolts (one millivolt is one thousandth of a volt). This is to be compared with the voltage at a power socket in your home of 110 volts - a thousand times bigger. This signal is passed onto other neurons at the synapse points in the following way.
