For example, neuroimaging studies have shown that exposure to appetising food cues results in preferential activation of hedonic regions of the human brain, and that obese individuals show greater activation ... Two studies have also combined hormones with neuroimaging of responses to food stimuli to examine the effect of long-term or genetic alterations of signalling on appetite and body weight in humans. ...doi:10.1111/j.1365-2826.2010.02025.x pmid:20553371 pmcid:PMC3121301 fatcat:h2sbvbe4jve47j4kp5ag5x2cxm
In this review, we discuss the role of the brain melanocortin system in causing increased sympathetic activity in obesity and other forms of hypertension. ... In addition, we highlight potential mechanisms by which the brain melanocortin system modulates metabolic and cardiovascular functions. ...

Another brain area that would be of interest to analyze is the prefrontal cortex, where significant abnormali- ties were documented in obese subjects presented with food- related stimuli (16). ...

The present study examined whether personal food-related preferences would activate approach and avoidance systems, modulating spontaneous postural sway toward and away from food items. ... Appetitive motivational states are fundamental neural and behavioral mechanisms underlying healthy and abnormal eating behavior, though their dynamic influence on food-related behavior is unknown. ... The appetitive system is responsible for approach-related behavior, and is activated in response to pleasant and rewarding stimuli. ...doi:10.1371/journal.pone.0072432 pmid:24023618 pmcid:PMC3758305 fatcat:yikudtpypzczjis5ew536omp6e
Olfactory influences on appetite and satiety in humans. PHYSIOL BEHAV. 200X; 00(X): 000-000. Odor stimuli play a major role in perception of food flavor. ... Overall, these studies suggest that once an odor is experienced in a food-related context, that odor acquires the ability to modify both preparatory and satiety-related components of ingestion. ... Olfactory sensory-specific satiety has been shown to relate to activation of the orbitofrontal cortex in humans  , based on the observation that activation of the orbitofrontal area by banana odor ...doi:10.1016/j.physbeh.2006.01.029 pmid:16545846 fatcat:pjrxpghwjfejnb4jgh2axlmrri

Oro-sensory exposure to food affects satiation by direct signaling via the brainstem to higher cortical regions involved in taste and reward, including the nucleus accumbens and the insula. ... Critical brain areas for satiation, such as the brainstem, should be studied more intensively to better understand the neurophysiological mechanisms underlying the process of satiation. ...
