It is becoming clearer how neurobiological mechanisms generate 'liking'and
'wanting'components of food reward. Mesocorticolimbic mechanisms that enhance …

Plants produce many volatile metabolites. A small subset of these compounds is sensed by
animals and humans, and the volatile profiles are defining elements of the distinct flavors of …

For the past 35 years, learning theorists have been providing models that depend on mental
representations, even in their most simple, deterministic, and mechanistic approaches …

In a restrictive food environment, the homeostatic control system regulates body weight and
adiposity with remarkable precision. However, this regulation appears to break down in …

Affective processes are a key determinant of behaviour: At its simplest, liked stimuli are
approached while disliked stimuli are avoided. Although assessing hedonic responses in …

Tasty high-fat and high-sugar foods induce overeating and obesity in animals. To separate
the roles of oral and postoral factors in food preference and consumption, recent studies …

The palatable, energy‐dense foods that characterize modern environments can promote
unhealthy eating habits, along with humans' predispositions to accept sweet tastes and …

Obesity is new in human evolutionary history, having become possible at the population
level with increased food security. Across the past 60 years, social, economic, and …

The gustatory system serves as a critical line of defense against ingesting harmful
substances. Technological advances have fostered the characterization of peripheral …

Reward is fundamental to the organization of behavior, and the neurotransmitter dopamine
(DA) is widely recognized to be critical to the neurobiology of reward, learning and addiction …
