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.
Inducing massive inflammation resulted in an overexpression of Trpv4. The overexpression led to neural hyperexcitability that resulted in social avoidance behaviors associated with ASD in mouse models.
A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.
Researchers have identified a pre-programmed neural circuit in the basolateral amygdala of mice that processes both positive and negative stimuli.
The brain's reward system plays a key role in helping behaviors and empathy.
Researchers have identified a new reward system in the brain. The study found long-range GABA neurons from the ventral tegmental area to the ventral nucleus accumbens shell are engaged in reward and reinforcement behaviors. This GABAergic projection inhibits cholinergic interneurons.
The stronger the connection between the dorsolateral prefrontal cortex and temporal-parietal junction, the less likely people are to punish others for selfish deeds.
Study reveals the types of foods you load your plates with at all you can eat buffets may predict your risk for obesity.
When a rat helps another within its social group, brain areas associated with reward and motivation become more active. This does not occur when a rat is faced with the prospect of helping another rat outside its social group. Researchers say the findings may provide a better understanding of similar social biases in humans.
