In mice genetically more susceptible to PTSD following a stressful event, researchers found an increased expression of cortisol receptors on neurons in the CA1 region of the dorsal hippocampus. Those increased receptors enabled an elevated expression of the HCN1 protein and TRIP8b, reducing neural excitability.
Spironolactone, a medication commonly used to lower blood pressure and for treating heart-related problems, shows potential for the treatment of alcohol use disorder.
Early birds use more fat for energy during both rest and exercise than night owls.

NG2-glia, a newly discovered type of brain cell that can renew itself is regulated by circadian rhythms. The findings shed new light on how the body's circadian clock can promote healing following a traumatic brain injury.
A neural pathway that leads directly from the thalamus to the hypothalamus plays a critical role in processing touch information, a new study reveals.
A new study finds that the prevalence of depression is highest in women, adolescents, and young adults.
Researchers have mapped four new areas of the human anterior prefrontal cortex that play critical roles in cognitive processing. Two of these newly mapped areas are larger in females than in males.
The emotional expressions of faces influence how their gazes shape our attention.
Teenagers with problematic alcohol use are more likely to experience poorer health and worse life satisfaction during their mid-thirties.
The stressful events of 2020 may have harmed the social development of young people at a crucial point in their lives, a new study reports.
