Separable Substrates for Anticipatory and Consummatory Food Chemosensation
Perception of the smell of a food precedes its ingestion and perception of its flavor. The neurobiological underpinnings of this association are not well understood. Of central interest is whether the same neural circuits code for anticipatory and consummatory phases. Here, we show that the amygdala and mediodorsal thalamus respond preferentially to food odors that predict immediate arrival of ...

متن کاملAnhedonia and depression: Anticipatory, Consummatory, and Recall Deficits

Sixty-one depressed and non-depressed, college-student participants provided reports of anticipated pleasure to tasting chocolates, tasted chocolates and rated their experience of pleasure, and provided recalled reports of pleas...
متن کاملIncreased anticipatory but decreased consummatory brain responses to food in sisters of anorexia nervosa patients
BACKGROUND We have previously shown increased anticipatory and consummatory neural responses to rewarding and aversive food stimuli in women recovered from anorexia nervosa (AN). AIMS To determine whether these differences are trait markers for AN, we examined the neural response in those with a familial history but no personal history of AN. METHOD Thirty-six volunteers were recruited: 15 ...
متن کاملRelationship between anticipatory, consummatory anhedonia and disorganization in schizotypy
BACKGROUND The disorganized and negative dimensions of schizotypy are characterized by cognitive disorganization and anhedonia, respectively. The aim of the study was to investigate the relationships between these two dimensions of schizotypy by taking into account ambivalence and the distinction between consummatory and anticipatory anhedonia. METHODS Dimensional analysis and categorical ana...
