Alliesthesia ( (allós) - other, and (aísthēsis) - sensation, perception ; ''French'' : ''alliesthésie'', ''German'' : ''Alliästhesie'') describes the dependence of the perception of pleasure or disgust perceived when consuming a stimulus on the "milieu intérieur" of the organism. Therefore, a stimulus capable of ameliorating the state of the interior milieu, will be perceived as pleasant. In contrary, a stimulus disturbing the ''milieu interne'' of the organism will be perceived as unpleasant or even painful. The sensation elicited therefore depends not only on the quality or on the intensity of the stimulus, but also on internal receptors, and is subjective. Alliesthesia is a physiologic phenomenon and should not be confounded with the pathologic symptom of allesthesia. Another phenomenon based on sensory cues and not to be confound with alliesthesia is "sensory-specific satiety". == Forms of alliesthesia == * ''thermic'' alliesthesia: alliesthesia of the thermic perception (heat and cold), which contributes fundamentally to homeostatic thermoregulation * ''olfactory'' alliesthesia: alliesthesia of olfaction (sense of smell) * ''gustatory'' alliesthesia: alliesthesia of taste - see primary tastes (sweet, salty, bitter, acid, umami and "calcium") * olfacto-gustatory alliesthesia or alimentary alliesthesia: alliesthesia of tastes/flavors pertaining to food intake * ''visual''/optic alliesthesia: alliesthesia of vision * ''auditory'' alliesthesia: alliesthesia of the sense of hearing Each of these forms of alliesthesia exists in two opposite tendencies: * ''negative'' alliesthesia: transformation of the sensation from pleasure to displeasure * ''positive'' alliesthesia: transformation of the sensation from displeasure to pleasure 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「alliesthesia」の詳細全文を読む スポンサード リンク
