Functional Design of the Nervous System,tem are called neurons. In some primitive invertebrates we find a simple network of undifferentiated nerve cells. In contrast, the human neurons show great variations in their shapes in relation to their specialized functions. The bulk of nerve cell bodies are collected in the central nervous system

The Excitability of Cells,ions. Different ionic concentrations on both sides of the membrane cause a difference in electrical potential or ‘voltage’. While at rest, the inside of the cell is about 70. more negative than the extracellular fluid. This state is called ‘.’. Whenever nerve cells or muscle fibers are active the vo

Modeling the Membrane,nly some of the channel types involved in the excitation processes. The gating mechanism also depends on the concentration of transmitters and several other parameters. This situation seems to be confusing when trying to model the effects of electrostimulation. Fortunately, functional electrostimula

Repetitive Firing and Fiber Reactions to Periodic Stimuli,nformation over distances greater than several millimeters. Many nerve cells are able to generate trains of impulses of constant or varying frequencies. Rythmic firing of the pacemaker cells is modulated by the transmitters adrenaline and acetylcholine, but the firing frequencies of axons can also b
