When their brains are stimulated with leptin, an appetite-suppressing hormone, hungry mice prioritize mating and interacting with mice of the opposite gender over eating.
Our bodies can predict the timing of regular meals, a new study reports. Additionally, a person's daily blood-glucose rhythms may be driven by meal size in addition to meal time.
Eating your largest meal at breakfast time may help decrease appetite for the rest of the day but it does not affect the way in which the body metabolizes calories in a different way to any other meal.
AgRP neurons in the hypothalamus play a critical role in shaping the structure and function of the prefrontal cortex in mice. The findings shed light on how the prefrontal cortex is altered in disorders such as schizophrenia.
In males, sun exposure activates the p53 protein which signals to the body to produce the appetite-associated ghrelin hormone. In women, estrogen blocks the interaction between p53 and ghrelin, reducing the urge to eat following sun exposure.
Lab-based studies revealed hunger was associated with increased irritability and stronger feelings of anger, along with a decrease in feelings of pleasure.
Researchers have identified a brain region and neural circuitry that mediates satiation.
Constant hunger associated with Prader-Willi syndrome is, in part, the result of disordered signaling in the cerebellum, an area of the brain associated with motor control and learning.
The brain regulates both eating for hunger and pleasure through serotonin-producing neurons in the midbrain, but the different types of feeding are wired by independent circuits that do not influence the other type of feeding.
The findings of a new study in mice may shed light on why dieting humans have a hard time sticking to food restrictions.
Researchers have identified a subpopulation of dopaminergic neurons in the caudal ventral tegmental area that appears to suppress food intake by triggering satiation in mice.
A study of hungry mice sheds new light on the neurobiology of olfaction and food attraction. Researchers identified a pathway that promotes attraction to food odors over other olfactory cues.
