Animal study connects fear behavior, rhythmic breathing, brain smell center

There's increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion. Now researchers have added neurons associated with the olfactory system to the connection between behavior and breathing. Connecting patterns in these interactions may help[…]

Neurons derived from super-obese people respond differently to appetite hormones

Scientists have successfully generated hypothalamic-like neurons from human induced pluripotent stem cells (hiPSCs) taken from the blood and skin cells of super-obese individuals and people with a normal body weight. The researchers found that the brain cells derived from the[…]

Gene variant increases empathy-driven fear in mice

A small difference in a gene affecting brain circuitry explains variations in empathic fear among different inbred mice strains. As empathy is evolutionarily conserved from rodents to humans, the study brings new insights into the workings of the mammalian brain[…]

Pregnant moms and their offspring should limit added sugars in their diets to protect childhood cognition

A new study has determined that poorer childhood cognition occurred, particularly in memory and learning, when pregnant women or their offspring consumed greater quantities of sugar. Substituting diet soda for sugar-sweetened versions during pregnancy also appeared to have negative effects.[…]
