Why do many Canadians get the winter blues? In the first study of its kind in the living human brain, Dr. Jeffrey Meyer and colleagues at the Center for Addiction and Mental Health (CAMH) have discovered greater levels of serotonin transporter in the brain in winter than in summer. These findings have important implications for understanding seasonal mood change in healthy people, vulnerability to seasonal affective disorders and the relationship of light exposure to mood. CAMH's scientific...

Researchers in Italy say an imbalance of the neuronal signal serotonin in the brain stem may help explain Sudden Infant Death Syndrome. A team at the European Molecular Biology Laboratory in Monterotondo, Italy, said the brain stem, the lower part of the brain that forms the link to the spinal cord, coordinates many fundamental functions, including control over cardiovascular and respiratory systems. Cornelius Gross and his group modified the serotonin system of mice to understand the...

A new thesis from the Swedish medical university Karolinska Institutet shows that the brain's serotonin system differs between men and women. The scientists who conducted the study think that they have found one of the reasons why depression and chronic anxiety are more common in women than in men. Serotonin is a brain neurotransmitter that is critical to the development and treatment of depression and chronic anxiety, conditions that, for reasons still unknown, are much more common in women...

Patients should talk to their doctors before discontinuing antidepressant or...

By Charnicia Huggins NEW YORK (Reuters Health) - Melatonin, a hormone involved in the regulation of the sleep/wake cycle, may help night shift workers get more rest during daylight hours, according to the findings of a small study published in the journal Sleep. Melatonin, which is released by the brain primarily during the hours of sleep, is also available as an oral supplement. "If for reasons of being a shift worker or due to travel across time zones you have to sleep at a strange hour,...

STANFORD, Calif. - Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab. A professor of neurology and neurological sciences and chair of the immunology program, Steinman, MD, and his lab generally focus on high-tech genetic therapies for diseases of the brain and nervous system. But his latest paper, to be published in the Nov. 4 issue of Science, breaks new ground on the effects of...

Some, like serotonin, seem to contribute to anxiety, researchers say HealthDayNews -- Research continues to reveal the effect chemicals can have on the brain and how well it works. What is emerging from intensive studies is the influence of certain chemicals already found in the brain. Scientists are looking for ways to make those substances more adaptable to individual needs. Many of these neurochemicals are contained in brain cells known as neurons. Although there are millions of neurons in...
