Study Sheds Light on Nicotine's Addictive Power
More than four million people die from smoking-related causes each year, making nicotine addiction a leading cause of preventable mortality worldwide. But nicotine's highly addictive nature makes kicking the smoking habit very difficult. New research identifies brain receptors in mice that may help explain why it's so hard to quit, and help scientists develop new drugs to help smokers butt out.

Health Plays Part in Marital Bliss. MONDAY, Oct. 11 (HealthDayNews)
Satisfaction with marriage is affected by the mental health of both spouses, says a study in the October issue of the Journal of Consulting and Clinical Psychology. The study of 774 married couples from seven states in the United States found that each spouse's level of anxiety and depression predicted their own marital satisfaction and that of their spouse as well. The more depressed or anxious either spouse was, the more dissatisfied he or she was with the marriage.

Everett Koop on "Medicine, Mind, and Meaning," by Eve A. Wood
C. Everett Koop, former U.S. Surgeon General and McInerny Professor of Surgery, Dartmouth Medical School, writes the foreward to Medicine, Mind, and Meaning (2004), a new book by noted psychiatrist, professor and speaker, Eve A. Wood. The book is a step-by-step guide that combines traditional psychiatric approaches and spiritual principles. Not typically given to publicly endorsing work, Koop's exception in this case marks the importance and urgency he attaches to this text. Koop writes, "I have seldom been so moved by a book. This is the only healing model that makes sense."
Make Promiscuous Animals Monogamous By Manipulating Genes. ATLANTA
Researchers at the Yerkes National Primate Research Center of Emory University and Atlanta's Center for Behavioral Neuroscience (CBN) have found transferring a single gene, the vasopressin receptor, into the brain's reward center makes a promiscuous male meadow vole monogamous. This finding, which appears in the June 17 issue of Nature, may help better explain the neurobiology of romantic love as well as disorders of the ability to form social bonds, such as autism. In addition, the finding supports previous research linking social bond formation with drug addiction, also associated with the reward center of the brain.
Researchers Study The Effects Of Zen Meditation On The Brain
Zen meditation is an ancient spiritual practice that promotes awareness and presence through the undivided engagement of mind and body. For thousands of years, many religious traditions have made meditation a common practice. Now, researchers at Emory University are looking at the effects of Zen meditation and how the brain functions during meditative states. By determining the brain structures involved in meditation and whose activity is gradually changed in the course of long-term meditative practice, researchers hope this training could one day be used as a complementary treatment for neurological conditions, such as Parkinson's disease and attention deficit and hyperactivity disorder (ADHD).
According to attachment theory, certain children must be subjected to physical "confrontation" and "restraint" to release repressed abandonment anger. The process is repeated until the child is exhausted and emotionally reduced to an "infantile" state. Then the parents cradle, rock and bottle-feed him, implementing an "attachment." This is pseudoscientific quackery masquerading as psychological science and, put into practice, it can be deadly.

Brain in Love
Most people think of romantic love as a feeling. Helen Fisher, however, views it as a drive so powerful that it can override other drives, such as hunger and thirst, render the most dignified person a fool, or bring rapture to an unassuming wallflower.
Thoughts Resurface in Dreams
"Wishes suppressed during the day assert themselves in dreams," Sigmund Freud wrote more than a century ago. Now new research provides evidence suggesting that not just wishes but all kinds of thoughts we bar from our minds while awake reappear when we sleep.
The Christian philosopher Saint Augustine described two types of evil. "Natural evil" is what happens when a volcano erupts or a storm strikes, while "moral evil" includes all the dreadful things that humans knowingly do to each other. Over the past decade, neuroscientists have found that the brains of impulsive murderers and psychopaths are fundamentally different from those of "normal" people. Those differences extend even to their ability to make choices--to exercise free will. Sean Spence, a British psychologist, asks how we should deal with these findings. For some people, should we move the boundary between what is moral and natural evil?
Support Has Lifelong Benefits MONDAY, March 22 (HealthDayNews)
Abundant parental support during childhood leads to better mental and physical health throughout adulthood, a new study finds. Conversely, a lack of love is associated with depression and chronic health problems, says Benjamin A. Shaw.
on the brain
MU psychiatrist's book investigates effects of religion on psyche (Columbia Daily Tribune, Mo.).
A brain circuit long considered a no-go area could be the key to a new class of molecule that will revolutionise the treatment of mental illness - including many intractable or poorly treated diseases such as schizophrenia, epilepsy, addiction, anxiety and chronic pain. The compounds, being developed by almost every major pharmaceutical company, are based on glutamate, the brains primary neurotransmitter. Glutamate signalling is so pervasive in the brain that interfering with it usually leads to horrendous side effects. But researchers have found promising ways to control it selectively for the first time, so there is now a real prospect of taking control of the brains master switch.

of books to sort out love, lust
The images of love that are promoted by American culture often don't lead to happiness (The Tennessean).
New research indicates that chronic drug use induces changes in the structure and function of the system's neurons that last for weeks, months or years after the last fix. These adaptations, perversely, dampen the pleasurable effects of a chronically abused substance yet also increase the cravings that trap the addict in a destructive spiral of escalating use and increased fallout at work and at home. Improved understanding of these neural alterations should help provide better interventions for addiction, so that people who have fallen prey to habit-forming drugs can reclaim their brains and their lives.

Two personas trigger different brain networks. One human brain can have two different personalities dwelling in it, according to a new imaging study - and each personality seems to use its own network of nerves to help recall or suppress memories. Alternative personalities are typically developed by children who suffer severe trauma or abuse. The condition, called multiple personality disorder, or dissociative identity disorder, appears to help people cope by cutting off difficult memories, making them seem as if they happened to someone else. Nature, 9 January 2004
Intelligence in the workplace is not that different from intelligence at school, according to the results of a meta-analysis of over one hundred studies involving more than 20,000 people. The findings contradict the popular notion that abilities required for success in the real world differ greatly from what is needed to achieve success in the classroom. The results are published in the January issue of the American Psychological Association's (APA) Journal of Personality and Social Psychology.

Reveals Brain Has Biological Mechanism To Block Unwanted Memories.
For the first time, researchers at Stanford University and the University of Oregon have shown that a biological mechanism exists in the human brain to block unwanted memories. The findings, to be published Jan. 9 in the journal Science, reinforce Sigmund Freud's controversial century-old thesis about the existence of voluntary memory suppression.
For decades, theories of schizophrenia have focused on a single neurotransmitter: dopamine. In the past few years, though, it has become clear that a disturbance in dopamine levels is just a part of the story and that, for many, the main abnormalities lie elsewhere. In particular, suspicion has fallen on deficiencies in the neurotransmitter glutamate. Scientists now realize that schizophrenia affects virtually all parts of the brain and that, unlike dopamine, which plays an important role only in isolated regions, glutamate is critical virtually everywhere. As a result, investigators are searching for treatments that can reverse the underlying glutamate deficit.
