When a 1/2 to 2% solution of cocaine is injected into a mixed nerve or into the subdural canal, the selective action is very marked, so that there is complete anesthesia, without motor impairment. If the contact is prolonged, by stopping the circulation, or if stronger solutions are employed, the motor fibers become paralyzed, so that the difference is merely quantitative. A similar difference in the susceptibility of motor and sensory structures exists also for the alcohol group, aconitine, phenol, hydrocyanic acid, and for pressure, and even for the centrally acting narcotics, ether, etc. It is therefore a characteristic of nervous tissue rather than of cocaine. It is now generally... 

There are two physical processes involved in the movement of molecules from one place to another (such as from the air to the surface of a sensory structure) - the molecules may walk themselves, or they may be pushed. Diffusion is the... 

For any speciation process based on pheromonal communication to be effective, variation in CHC production should tightly co-evolve with factors regulating CHC processing. This has been observed for the desatl gene in D. melanogaster (Marcillac et al., 2005b). Such coevolution requires that pre-existing sensory structures can detect and respond to new CHC molecules. This basic assumption of the theory of sexual selection is supported by the observation that taste neurons normally used to detect bitter molecules also serve to detect an aversive sex pheromone (Lacaille et al., 2007). It is thus possible that taste neurons that were initially used by the fly to detect noxious food molecules (bitterness is often associated with alkaloids and toxic molecules) have been more recently used to detect inhibitory sex pheromones. 

As a sensory structure. The skin contains receptors providing information about our surroundings and changes in the environment. The receptors are part of the nervous system and those in the skin are sensitive to touch,... 

Some of the sensory structures on skin include receptors to detect taste, touch, and vibrations. Whiskerlike skin outgrowths called barbels act as fingers, enabling a fish to feel around for prey that might be hidden below sand or sediment. In some types of fish, the barbels contain receptors of taste and smell.

In terrestrial habitats, the risk of desiccation through diffusion of water to the environment makes robust sensory structures necessary, where pore systems provide access for stimulatory molecules into the insect sensilla (Altner and Prillinger 1980).

The sensory system of any animal has presumably evolved under sources of selection generated by its environment. In an aquatic environment, for example, one expects animals to be able to sense fluid dynamics, since chemical cues important for survival are necessarily embedded in these movements (Mellon 2007). Not surprisingly then, aquatic crustaceans possess multiple fluid-flow detectors, chemoreceptors, and even bimodal chemo-mechanoreceptors (Hallberg and Skog, Chap. 6). A wealth of literature exists on all of these sensory structures and the... 

However, the relationship between the odors of single odorants and their mixtures can be investigated without regard to the molecular structures of these odorants. The sensory structures of the odors of single component odorants can be characterized, e.g., by multidimensional scaling. The sensory structure of an odorant mixture can also be characterized by some means, and then rules can be explored which tie the odor of the mixture to the odor of components.

The Flash Profile is a quick sensory descriptive method derived from Free Choice Profiling (Williams and Langron, 1984 Williams and Arnold, 1985). It was initially developed as a way to rapidly position products according to their major sensory characteristics (Dairou and Sieffermann, 2002 Sieffermann, 2002). The method allows semantic flexibility, since it does not rely on a consensual description. As a result. Flash Profile can be used to rapidly assess a whole set of stimuli, from which to extrapolate insights into the way subjects perceive factors under investigation (Ballay et al. 2003 Delarue et al, 2004). The method allows quick access to the overall sensory structure of a sample set, which is important in understanding the main sensory differences, or similarities, between products associated with a semantic description (Delarue and Sieffermann, 2004).

Piezo sensors enable an implementation of smart structure concepts in two ways the so-called adaptive and the sensory structures [106]. 

Sensory structures however, are able to detect and monitor deformations, deflections or even structural conditions and properties (e. g. the growth of damages) via integrated sensors. In the case of a critical condition or property an output of information about the actual condition or just a warning will be generated. This kind of condition monitoring (CM) is also called structural health monitoring (SHM).
