The neurophysiology of taste and smell

This review briefly summarizes the main anatomical and fonctional organizat ion of the chemical senses involved in the control of the food intake, the gustary and the olfactory systems. Both systems cooperate for the complexe sensation commonly named "taste". For both systems the histological structu re of the peripheral receptors was briefly presented, as well as the main n eural pathways in the central nervous system. We also briefly presented the transduction process of the sensorial informations according to the theori es of the "computerized model" or the model of "dedicaced lines".
