          Hair Cortisol Levels in Infants May Predict Sleep Patterns

          Cortisol levels in late pregnancy may predict an infant's sleep patterns. Higher cortisol levels in neonates were found to be associated with longer sleep latency at 7 months.

          New Discovery Reveals Sex-Specific Causes of Depression Triggered by Stress Hormones Dysfunction

          Men are more likely to have a dysregulated HPA axis that is associated with depressive symptoms, while women have higher levels of binding proteins for stress hormones that may prevent dysregulation of the HPA axis. The findings shed new light on how stress hormones impact dopamine transmission and how this impacts depression on a sex-specific basis.

          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.

          Neurosteroid Deficits Leads to Depressed Behavior

          Chronic stress impairs allopregnanolone production in the basolateral amygdala, a brain area associated with mediating emotional response. The reduction of this neurosteroid results in depressive symptoms in animal models.

          Molecular Changes in the Brain in the Aftermath of a Traumatic Event May Help Explain Long-Term Susceptibility or Resilience

          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.

          Cognitive Biases and Brain Biology Help Explain Why Facts Don’t Change Minds

          Our worldview forms during childhood as a result of our socialization within a particular cultural context. Our views get reinforced over time by the social groups we keep, the media we consume, and even the way in which our brains are wired. Challenging our worldviews with facts can feel like an attack on our personal identities and can often result in hardening our positions. Researchers assess how we can open our minds and explore facts that may go against our personal worldviews.
