An internal representation of the external world is created in the brain of all eukaryotes by a mechanism that detects chemicals in the environment and transmit this information to the brain, where it is processed to create, at least in humans, perceptions. This sensory representation of the external chemical world in the brain is a translation of stimulus features into a neural sensory map. It is the nature of this sensory map: how it is established by stimulant patterns, how it varies in a population, and ultimately how it modulates other brain functions, e.g. emotions (joy) or behavior (buying wine), that is the goal of our research. Over the years Terry and his students have developed a selective and sensitive bio-assay for smell based on gas chromatography - olfactometry (GCO) called CharmAnalysis that, along with other forms of chromatography, spectrometry, and sensory analysis, are used to study food quality.
