Brain electric field sense of some types of fish. Each sensory system begins with specialized receptor cells, such as light-receptive neurons in the retina of the eye, or vibration-sensitive neurons in the cochlea of the ear. The axons of sensory receptor cells travel into the spinal cord or brain, where they transmit their signals to a first-order sensory nucleus dedicated to one specific sensory modality. This primary sensory nucleus sends information to higher-order sensory areas that are dedicated to the same modality. Eventually, via a way-station in the thalamus, the signals are sent to the cerebral cortex, where they are processed
Common Source Data Base Common Source Data Base Technical documentation is used in many areas of the everyday life. Nearly everything has to be provided with at minimum a drawing including a few locators. The product liability and many other issues regarding consumer protection have to be covered inside technical documentation. A special form of technical documentation is electronic technical documentation, a further subform is interactive electronic technical documentation (IETD). The complexity of IETD especially regarding the huge mass of data elements, their linkage and the version management issuing and release process must be controlled via a special document management system. To handle these
