Maternal stress may disrupt masculinization of developing mouse brain

Sons of male mice exposed to prenatal stress are more sensitive to stress as adults, according to a study in the August 17 issue of The Journal of Neuroscience. These findings suggest experiences in the womb can lead to individual differences in stress response that may be passed across generations.

Researchers to unravel how brain makes everyday prognostications

Every day we make thousands of tiny predictions - when the bus will arrive, who is knocking on the door, whether the dropped glass will break. Now, in one of the first studies of its kind, researchers at Washington University in St. Louis are beginning to unravel the process by which the brain makes these everyday prognostications.

Ultrasound can predict high risk of stroke in patients with asymptomatic carotid stenosis

A new study shows that a simple ultrasound test may help to identify people at high risk of stroke who have a condition called asymptomatic carotid stenosis, a narrowing of the carotid artery found in the neck, in which few or no symptoms are present.

Addiction – a brain disorder say experts

According to the American Society of Addiction Medicine, addiction is a chronic brain disorder like any other chronic brain disease such as obsessive-compulsive disorder and body dysmorphic disorder. Neurological abnormalities like disruptions in neurotransmission and the reward system drive addiction, the group said in a statement.

Researchers document how immune system can counteract advancement of Alzheimer's

For the first time a research team at Charité - Universitätsmedizin Berlin and Universitätsklinik Freiburg succeeded in documenting how the immune system can counteract the advancement of Alzheimer's disease.

Study: Eye contact seems to act as an invitation for mimicry

Imitation may be the sincerest form of flattery but how do our brains decide when and who we should copy? Researchers from The University of Nottingham have found that the key may lie in an unspoken invitation communicated through eye contact.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

PTSD impairs ability to recognize emotions from facial expressions

Facial expressions convey strong cues for someone's emotional state and the ability to interpret these cues is crucial in social interaction. This ability is known to be compromised in many psychiatric and neurological disorders, such as social anxiety or Korsakoff's syndrome.

Fluctuations in brain signals explained: Spontaneous electrical background rhythms in the brain influence fMRI

Until now, brain scans obtained using fMRI – one of the most important imaging methods in use today – have been affected by fluctuations in the brain activity measured which could not be explained. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the Charité in Berlin have now shown that certain electric background rhythms in the brain, known as Alpha oscillations, alter the fMRI signal obtained with visual stimuli. To do this, they used a new approach in which quickly changing brain activity, which cannot be captured by the scanner, was measured using

Study investigates autism spectrum disorder, sibling recurrence

The risk that an infant with an older sibling with autism also will develop the disorder, previously estimated at between 3 and 10 percent, is substantially higher at approximately 19 percent, a large, international, multi-site study led by researchers at the UC Davis MIND Institute has found.

Scientists define relationship between two prostate tumor suppressor genes

Of the 250,000 American men who will be diagnosed with prostate cancer this year, very few of them-about 1 percent-will develop lethal, metastatic disease. Finding a way to distinguish between this small cohort and the majority of patients who will develop an indolent, non-lethal form of prostate cancer is a key goal in prostate cancer research.

Modified Cdk5 enzyme triggers damage to nerve cell connections in human Alzheimer's brains

Alzheimer's disease is characterized by abnormal proteins that stick together in little globs, disrupting cognitive function. These sticky proteins are mostly made up of beta-amyloid peptide. A better understanding of these proteins, how they form, and how they affect brain function will no doubt improve the diagnosis and treatment of Alzheimer's disease.

Novel assay can accurately detect prostate cancer than traditional screening

new prostate screening test developed by AnalizaDx, Inc., a Cleveland-based biotech company, and studied by researchers at the Seidman Cancer Center at University Hospitals (UH) Case Medical Center along with colleagues at the Cleveland Clinic, the Veterans Administration Boston Healthcare and the National Cancer Institute, may prove to be a promising new tool in the diagnosis of prostate cancer.

New role for harmonin protein in Usher syndrome

University of Iowa scientists have discovered a new role for a protein that is mutated in Usher syndrome, one of the most common forms of deaf-blindness in humans. The findings, which were published Aug. 8 in Nature Neuroscience, may help explain why this mutation causes the most severe form of the condition.
