Illuminating mechanisms of repetitive thinking

tir, 07/28/2015 - 17:03
The ability to engage in mental time travel is a unique and central part of the human experience. And yet this very ability can have detrimental consequences for both physical and mental well-being when it becomes repetitive and uncontrolled. New research investigates this kind of repetitive thinking, exploring the core psychological processes that underlie maladaptive thought processes like worry and rumination.

National study of deep brain stimulation for depression fails to demonstrate efficacy

tir, 07/28/2015 - 17:03
Depression is a leading cause of disability worldwide, and treatment-resistant symptoms of depression have a terrible personal and societal cost. They can devastate lives, careers, and families. Some severely ill patients may be unable to attend to even the basic elements of self-care, while others attempt or complete suicide. Now researchers report the results of the first large-scale, randomized, sham-controlled trial of deep brain stimulation treatment for treatment-resistant symptoms of depression.

Practice doesn't always make perfect (depending on your brain)

tir, 07/28/2015 - 17:03
How do you get to Carnegie Hall? New research on the brain's capacity to learn suggests there's more to it than the adage that 'practice makes perfect.' A music-training study has found evidence to distinguish the parts of the brain that account for individual talent from the parts that are activated through training.

Hormones influence unethical behavior, experts say

tir, 07/28/2015 - 16:08
Hormones play a two-part role in encouraging and reinforcing cheating and other unethical behavior, according to new research. With cheating scandals a persistent threat on college campuses and financial fraud costing businesses more than $3.7 trillion annually, researchers looked to hormones for more answers, specifically the reproductive hormone testosterone and the stress hormone cortisol.

Link between intestinal bacteria, depression found

tir, 07/28/2015 - 16:07
The complex mechanisms of interaction and dynamics between the gut microbiota and its host have been illuminated by recent research. Data show that relatively minor changes in microbiota profiles or its metabolic activity induced by neonatal stress can have profound effects on host behavior in adulthood.

Link between mood, pain in rheumatoid arthritis patients

tir, 07/28/2015 - 16:05
Depressive symptoms and mood in the moment may predict momentary pain among rheumatoid arthritis patients, according to researchers. Individuals in the study who reported greater depressive symptoms in general also reported more common pain and restrictions in daily life. This effect of depressive symptoms was not due to differences in day-to-day mood.

Fatty acid increases performance of cellular powerhouse

tir, 07/28/2015 - 15:12
An entirely new control mechanism that regulates the function of mitochondria, the powerhouses of the cell, has been discovered by researchers. Surprisingly, a fatty acid is playing a key role in this process. The scientists have now reported that using fatty acid as a food additive improved disease symptoms in flies that suffer from Parkinson's-like symptoms due to dysfunctional mitochondria.

Where memory is encoded and retrieved: New findings in a long-standing debate

tir, 07/28/2015 - 14:19
Are the same regions and even the same cells of the brain area called hippocampus involved in encoding and retrieving memories or are different areas of this structure engaged? This question has kept neuroscientists busy for a long time. Researchers have now found out that the same brain cells exhibit activity in both processes.

Brain disease scenarios revised by step-by-step imaging of toxic aggregation

tir, 07/28/2015 - 14:17
Diseases like Alzheimer's are caused when proteins aggregate and clump together. In a world first, scientists have successfully distinguished between the disease-causing aggregation forms of proteins. The finding can help change pharmaceutical treatment of neurodegenerative diseases.

Very early birth linked to introversion, neuroticism, risk aversion in adulthood

tir, 07/28/2015 - 03:02
Babies born very premature or severely underweight are at heightened risk of becoming introverted, neurotic, and risk averse as adults, indicates research. Very premature birth at less than 32 weeks and/or very low birthweight of less than 1500 g are known to be linked to a heightened risk of autistic spectrum behaviours, but it has not been clear if prematurity and low birthweight might affect other adult personality traits.

A strikingly new approach for treating Rett syndrome has been developed by scientists, a devastating autism spectrum disorder. In their report, the researchers demonstrate that treatment with small-molecule drug candidates significantly extends lifespan in male mice that model Rett and ameliorates several behavioral symptoms in females.
