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.
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.
Researchers explain how stress can have a detrimental impact on your skin, nails, and hair.
Women who hug their partners before a stressful event have a lower biological stress response and reduced cortisol levels compared to women who do not embrace their partners.
The stress hormone cortisol reduces altruistic behaviors and alters brain activity in the dorsolateral prefrontal cortex in people with higher levels of empathy.
Mothers who use cannabis during pregnancy to relieve stress may be putting their children at risk of developing anxiety and stress later in life. Researchers found placental tissue revealed cannabis use in mothers was associated with lower expression of immune-activating genes. Cannabis suppression of placental immune-gene networks predicted higher anxiety in children.
Many people claim meditation helps to relieve their daily stresses. A new study provides objective evidence which supports the claims. Researchers found cortisol levels from hair samples decreased by 25% following a six-month meditation training program.
Reinterpreting stress response as performance-enhancing makes people less anxious and improves general wellbeing, researchers report.
