Predicting the life cycle of complex

Onset of depression more complex than a brain chemical imbalance Updated: April 11, Published: Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, stressful life events, medications, and medical problems.

To be sure, chemicals are involved in this process, but it is not a simple matter of one chemical being too low and another too high.

Rather, many chemicals are involved, working both inside and outside nerve cells. There are millions, even billions, of chemical reactions that make up the dynamic system that is responsible for your mood, perceptions, and how you experience life.

With this level of complexity, you can see how two people might have similar symptoms of depression, but the problem on the inside, and therefore what treatments will work best, may be entirely different. Researchers have learned much about the biology of depression.

One day, these discoveries should lead to better, more individualized treatment see "From the lab to your medicine cabinet"but that is likely to be years away. And while researchers know more now than ever before about how the brain regulates mood, their understanding of the biology of depression is far from complete.

What follows is an overview of the current understanding of the major factors believed to play a role in depression. Science, though, tracks the seat of your emotions to the brain.

Certain areas of the brain help regulate mood. Researchers believe that — more important than levels of specific brain chemicals — nerve cell connections, nerve cell growth, and the functioning of nerve circuits have a major impact on depression.

Still, their understanding of the neurological underpinnings of mood is incomplete. Regions that affect mood Increasingly sophisticated forms of brain imaging — such as positron emission tomography PETsingle-photon emission computed tomography SPECTand functional magnetic resonance imaging fMRI — permit a much closer look at the working brain than was possible in the past.

An fMRI scan, for example, can track changes that take place when a region of the brain responds during various tasks. Use of this technology has led to a better understanding of which brain regions regulate mood and how other functions, such as memory, may be affected by depression.

Areas that play a significant role in depression are the amygdala, the thalamus, and the hippocampus see Figure 1.

Research shows that the hippocampus is smaller in some depressed people. For example, in one fMRI study published in The Journal of Neuroscience, investigators studied 24 women who had a history of depression. The more bouts of depression a woman had, the smaller the hippocampus.

Stress, which plays a role in depression, may be a key factor here, since experts believe stress can suppress the production of new neurons nerve cells in the hippocampus. Researchers are exploring possible links between sluggish production of new neurons in the hippocampus and low moods.

An interesting fact about antidepressants supports this theory. These medications immediately boost the concentration of chemical messengers in the brain neurotransmitters.

The answer may be that mood only improves as nerves grow and form new connections, a process that takes weeks. In fact, animal studies have shown that antidepressants do spur the growth and enhanced branching of nerve cells in the hippocampus.

So, the theory holds, the real value of these medications may be in generating new neurons a process called neurogenesisstrengthening nerve cell connections, and improving the exchange of information between nerve circuits.World Academy of Science, Engineering and Technology 69 Predicting the Life Cycle of Complex Technical Systems (CTS) Khalil A.

Yaghi, Samer Barakat commonly bump into each other by the automobile vehicle Abstract—Complex systems are composed of several plain trailer during operation, and which can cause premature wear interacting independent entities. Life cycle cost analysis (LCCA) is a projection of initial and ongoing costs of ownership or leasing and operations for a facility or site over its useful life.

LCCA is used to determine the relative. Affective forecasting (also known as hedonic forecasting, or the hedonic forecasting mechanism) is the prediction of one's affect (emotional state) in the future.

As a process that influences preferences, decisions, and behavior, affective forecasting is studied by both psychologists and economists, with broad applications. The real system belongs to the complex physics model and data-mining area. Social network, like plombier-nemours.com, plombier-nemours.com and plombier-nemours.com, is a real-time complex system.
