Early-Life Stress Can Disrupt Maturation of Brain’s Reward Circuits, Promoting Disorders

Researchers have identified a novel stress-sensitive pathway in the reward system of the brain that releases corticotropin-releasing hormone in response to stress. Adverse experiences cause this pathway to become overactive.

Dynamic Expression of Brain Serotonin Receptors Across the Menstrual Cycle Provides Clues About Premenstrual Dysphoric Disorder

Roughly, 3 to 8% of women suffer from premenstrual dysphoric disorder (PMDD), a disorder that causes anxiety, depression, and mood swings during the menstruation cycle. PMDD appears to increase serotonin transporter density from the preovulation phase to the premenstrual cycle phase. The findings could aid in the development of new treatments for PMDD.

Brain Circuit Involved in Fentanyl Abuse and Relapse Identified

Fentanyl enhances direct pathway medium spiny neurons activity in the striatum. During withdrawal from the opioid, inhibitory signals from direct pathway medium spiny neurons to dopaminergic neurons become enhanced. The enhanced suppression of dopaminergic neurons contributes to the negative emotions associated with fentanyl withdrawal. Inhibiting the direct pathway medium spiny neurons can reduce withdrawal symptoms and associated anxiety behaviors.

Discovery in Zebrafish May Yield Better Understanding of a Range of Mental Health Disorders Related to Stress and Anxiety

Deficiencies in DSCAML1 disrupt normal brain development and increase baseline levels of cortisol, making the hormone less able to function correctly during periods of stress. The findings shed new light on programmed cell death in the developing brain and could lead to new treatments for mental health disorders including stress and anxiety.

Paying Attention to Faces May Be Linked With Psychopathology Levels and ‘Big Five’ Personality Traits

Those who are more empathetic and those who score high on extraversion, agreeableness, and openness personality traits are more likely to focus on faces. Those with psychological disorders including depression, anxiety, and alexithymia tend to focus less on faces.
