In Anxious Kids: Fear Center or Amygdala in Brain Larger
cytotec buy online New research suggests that altered childhood development of the small brain structure called the amygdala, or “fear center, ” may influence adult anxiety problems.
http://teen-spanking.com/?popka=delta-en-opciones-financieras delta en opciones financieras Researchers at the Stanford University School of Medicine recruited 76 children who were all between the ages of seven and nine—the period when anxiety-related traits and symptoms can first be identified reliably.1 The children’s parents completed assessments that were designed to measure the anxiety levels of the children, and the children underwent non-invasive magnetic resonance imaging (MRI) scans of the brain structure and function.1
