Scientists Find The “Physical Source” Of Depression |

A recent breakthrough may have found the physical source of depression in the brain. The discovery could lead to some game-changing developments in the way we treat and perceive the mental illness, while also taking a bold step in understanding the physical root cause of depression.

Research by the University of Warwick in the UK and Fudan University in China has shown that depression affects the lateral orbitofrontal cortex. This part of the brain becomes active when suffering punishment or when rewards are not received, suggesting depression could be associated with the sensation of not receiving reward.

Questions:

  • Why is there a stigma against people with depression or other mental ailments?
  • How can learning more about the causes of depression help people?
  • Some medicines can change the way you think, making you feel not like yourself. Would you take them if they could cure your illness?
  • Would you cut away parts of brain if they caused you depression?

Researcher Mary Carskadon and others at Brown University foundthat the human brain has a marked shift in its sleep/wake pattern during adolescence.

Researchers around the world corroborated those findings. At the onset of puberty, nearly all humans (and most mammals) experience a delay of sleep timing in the brain. As a result, the adolescent body does not begin to feel sleepy until about 10:45 p.m.

At the same time, medical researchers also found that sleep patterns of younger children enabled them to rise early and be ready for learning much earlier than adolescents.

In other words, the biology of the teenage brain is in conflict with early school start times, whereas sleep patterns of most younger children are in sync with schools that start early.

Questions:

  • Why do you think that this research is only available now? If this is a physical problem, it must have been known for a long time.
  • What are some issues when there isn’t enough sleep?
  • One suggestion to counter this problem is starting school later. What might some obstacles to this be?

The Brain that Changes

Andrew Short, who lives with cerebral palsy, and his trainer Lee, are applying the concept of neuroplasticity – that the brain can change – to overcome his disability.

Questions:

  • Is ability more important or effort?
  • How can a person who is limited by ability try to achieve more?
  • Should a person’s dreams and ambitions be limited by their ability?

Have you ever noticed how much clearer and focused your mind is when it is not cluttered? A cluttered mind is restless and unfocused. It can mean your vision is clouded, as your mind is moving in different directions at once, adding to your stress level when very little gets done.

Neuroscientists at Princeton University found that physical clutter in your surroundings competes for your attention, resulting in decreased performance and increased stress[1].
