  • Scientists have found that cultures of embryonic brain cells mature at the same rate as a 20-month-old infant's.
  • Researchers have looked to such cell structures, called "organoids," as potential models for understanding the human body's biological mechanisms.
  • Their study validates the use of lab-dish organoids for research.

  • Four research teams in four countries independently communicated with sleeping volunteers.
  • A total of 36 participants correctly responded to questions 18.6% of the time.
  • Researchers believe this could open up new avenues for treating anxiety, depression, and trauma.

7 dimensions of depression, explained

From baboon hierarchies to the mind-gut connection, the path to defeating depression starts with understanding its causes.

  • According to the World Health Organization, more than 264 million people suffer from depression. It is the leading cause of disability and, at its worst, can lead to suicide. Unfortunately, depression is often misunderstood or ignored until it is too late.
  • Psychologist Daniel Goleman, comedian Pete Holmes, neuroscientist Emeran Mayer, psychiatrist Drew Ramsey, and more outline several of the social, chemical, and neurological factors that may contribute to the complex disorder and explain why there is not a singular solution or universal "cure" that can alleviate the symptoms.
  • From gaining insight into how the brain-gut connection works and adopting a more Mediterranean diet, to seeking help from medical or spiritual practitioners, depression is a personal battle that requires a personalized strategy to keep it at bay, as well as more research and understanding.

  • Each hemisphere of your brain stores memories of the visual input from your opposite side.
  • Your working memory needs information from both hemispheres for you to effectively function.
  • To keep us aware of what's all around us, each hemisphere copies relevant memories to the other side when your gaze shifts.

    Risk-taking behavior has a unique and complex brain signature

    How much of this can be linked to genetics?

    • A study on more than 12,000 test subjects finds that risk aversion is related to how much gray matter people have in their brains.
    • A follow up on another 13,000 test subjects further supports the findings.
    • The study is not the last word on the nature versus nurture question.
