Psychotherapy could have diverse cerebral effects depending on certain genes

Problems like anxiety and depression are caused by psychological and environmental factors, and are known to be influenced by genetic proclivities. However, it is still not clear how each factor affects the brain's functions to induce anxious and depressive symptoms.

Advertisements seduce consumers to buy products

Are you wooed by advertising? Of course you are. After all, it's one thing to go out and buy a new washing machine after the old one exploded, quite another to impulse-buy that 246-inch flat screen TV that just maybe, in hindsight, you didn't really need.

Researchers discover molecular-level changes in brains of women with major depressive disorder

Researchers at the University of Pittsburgh School of Medicine have discovered molecular-level changes in the brains of women with major depressive disorder that link two hypotheses of the biological mechanisms that lead to the illness. Their results, published online this week in Molecular Psychiatry, also allowed them to recreate the changes in a mouse model that could enhance future research on depression.

New insight into why some individuals may be more aggressive than others

Fluctuations of serotonin levels in the brain, which often occur when someone hasn't eaten or is stressed, affects brain regions that enable people to regulate anger, new research from the University of Cambridge has shown.

U-M's epilepsy surgery could successfully treat patients with seizures

John Ligerakis was told he had to learn to live with seizures that had made it challenging for him to work or drive a car. A young professional just starting his career, Ligerakis was devastated about what his future might bring.

Conference to explore new discoveries about origins, diagnosis and treatment of tinnitus

University at Buffalo research showing that a new drug that eliminated tinnitus with a single dose in animal models is among the advances that will be presented at the Fifth Tinnitus Research Initiative Conference, "The Neuroscience of Tinnitus," sponsored by UB's Center for Hearing and Deafness Aug. 19-21 in Grand Island, N.Y.

Insight into how brain organizes during development

Scientists at the Allen Institute for Brain Science have taken an important step in identifying how the brain organizes itself during development. The findings, published in the Journal of Comparative Neurology today, describe - in more detail than ever before - the consequences of the loss of a key molecule involved in establishing proper brain architecture during brain development.

Meditation appears to change brain anatomy: Study

Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age.

Researchers find clear changes in how emotions are processed in smokers

A team of researchers led by the University of Bonn found clear changes in how emotions are processed in smokers. After an abstinence period of 12 hours, the brain's fear center was mostly out of commission in addicts.

Study reveals unique pattern of brain activity when false memories are formed

How easy is it to falsify memory? New research at the Weizmann Institute shows that a bit of social pressure may be all that is needed. The study, which appears Friday in Science, reveals a unique pattern of brain activity when false memories are formed - one that hints at a surprising connection between our social selves and memory.

‘City slickers’ at increased brain stress: Study

German and Canadian neuroscientists have shown that living in a city or even being raised in one is associated with differences in the way the brain handles stress. They write in Nature that this is the first time researchers have used functional magnetic resonance imaging (fMRI) to identify specific brain regions that are affected by urban life.

Urban dwellers at greater risk of mental illness: Study

A new study shows that living in a city increases the risk of developing a mental disorder, including depression and schizophrenia, compared to people who live in non-urban areas. The findings of the has implications for around half of the world's population who live in cities.
