Dopamine improves deficiencies in social behavior, could have implications for neuropsychiatric disorders

A stressful pregnancy might be the last thing a future mother needs, but it is to her unborn baby that this stress spells real trouble. All because stress hormones (called glucocorticoids or GCs) can disturb normal foetal brain development, leading to behavioural and/or emotional problems later in life.

NIH-funded study finds zebrafish model may help identify treatments for childhood epilepsy

According to new research on epilepsy, zebrafish have certainly earned their stripes. Results of a study in Nature Communications suggest that zebrafish carrying a specific mutation may help researchers discover treatments for Dravet syndrome (DS), a severe form of pediatric epilepsy that results in drug-resistant seizures and developmental delays.
