In this paper the term taste will refer to all the chemical sensory systems of the oral cavity and their sensations. These sensory systems are intimately involved in the selection of food items and in the regulation of food intake. As we shall see, there are a variety of different taste systems attuned to different chemical aspects of food. These taste systems perform an exact and elaborate analysis of the chemical constituents in the food we eat. 

Almost everyone is now utilizing the computer for statistical analysis of sensory data. Some laboratories also are using computers to gather the data as well (18). A computerized sensory system would benefit most laboratories by freeing workers from laborious data entry and analysis. Also, it would allow for a more thorough analysis of the data. It should not replace inspection of the raw data by the sensory scientist, but allow this to occur more easily.

This example demonstrates the most challenging problem of flavor chemistry, ie, each flavor problem may require its own analytical approach however, a sensory analysis is always required. The remaining unknown odorants demand the most sensitive and selective techniques, and methods of concentration and isolation that preserve the sensory properties of complex and often dehcate flavors. Furthermore, some of the subtle odors in one system will be first identified in very different systems, like o-amino acetophenone in weasels and fox grapes. 

A generalized systemic illness may accompany HIV seroconversion (Cooper et al. 1985). Guillain-Barre syndrome (GBS) (Piette et al. 1986), unilateral (Wiselka et al. 1987) or bilateral facial palsies (Wechsler and Ho 1989), bibra-chial palsy (Calabrese et al. 1987) and sensory neuropathy (Denning 1988) have been reported to occur during this process, usually within 1-2 weeks of the acute febrile illness. Spinal fluid analysis may show a mild to moderate mononuclear pleocytosis and a mild increase in protein levels. The precise relationship to HIV viral load in the cerebrospinal fluid (CSF) or plasma is unknown (Brew 2003). There is no proven therapy, but most patients recover spontaneously without any treatment. 

The neuropathological analysis of HIV-associated neuropathies should include the different central and peripheral nervous system structures associated with sensory pathways, including spinal cord, dorsal root ganglia (DRG), peripheral nerve, and cutaneous nerve fibers (Pardo et al. 2001) (Fig. 4.1). The majority of studies have focused on the evaluation of the peripheral nerve, often from sural nerve biopsies and the DRG. Few studies have examined the pathology of sensory pathways in the...

Task Analysis— An analytical process for determining the specific behaviors required of the human components in a man-machine system. It involves determining the detailed performance required of people and equipment and the effects of environmental conditions, malfunctions, and other unexpected events on both. Within each task to be performed by people, behavioral steps are analyzed in terms of (i) the sensory signals and related perceptions, (ii) the decisions, memory storage, and other mental processes, and (iii) the required responses.
