A new study sheds light on the neurobiology of cravings for certain foods women experience while pregnant. According to researchers, during pregnancy, the brain undergoes alterations to functional connections in the reward systems, as well as taste and sensorimotor centers. Pregnant females become more sensitive to sweet foods and develop binge eating behaviors toward high-calorie foods. Pregnancy induces a full reorganization of the mesolimbic neural circuits via D2R dopaminergic neurons in the nucleus accumbens.
According to researchers, young mice exposed to malaria while in the uterus had memory impairments and expressed depressive behaviors.
Prenatal diet could increase the risk of unhealthy eating and obesity in the offspring, a new study reports. Pregnant mice fed high omega-6 and low omega-3 diets were more likely to have offspring that were more inclined to consume hyper-caloric foods, increasing their risk of obesity.
Study reveals the precise hypothalamic neurons associated with mating motivation in mice. The findings could lead to new treatments for psychiatric disorders which do not impact libido.
Researchers report the brains of those who practice meditation are less affected by negative feedback than those who do not meditate. The study reports this could be due to altered dopamine levels caused by the act of meditation.
N-acetylcysteine appears to help enable dopamine neurons to recover some function, researchers report.
Researchers report transplanted nerve cells can survive for a number of years and restore dopamine production in Parkinson's patients.
Researchers report Parkinson's patients who received a combination of cognitive training and dopaminergic medication showed a significant reduction in the severity of their freezing of gait, a symptom associated with PD.
