Stress disrupts human thinking, but the brain can bounce back

A new neuroimaging study on stressed-out students suggests that male humans, like male rats, don't do their most agile thinking under stress.

New research reveals brain activity that underlies our tendency to "follow the crowd"

The study, published by Cell Press in the January 15th issue of the journal Neuron, provides intriguing insight into how human behavior can be guided by the perceived behavior of other individuals.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.

Neuronetrix announces preliminary study results for COGNISION System to diagnose Alzheimer's

Last week, at the Society for Neuroscience Conference in Washington DC, Neuronetrix announced preliminary results from a clinical study of their COGNISION System to diagnose Alzheimer's disease.

Drug-related preference in cocaine addiction extends to images

When given a choice between viewing pictures of cocaine and a variety of other images, cocaine addicted individuals, as compared to healthy, non-addicted research subjects, show a clear preference for the drug-related images.

MRI helps predict multiple sclerosis progression

A new study published in Journal of Neuroimaging shows that MRI scans used on multiple sclerosis (MS) patients to determine if the disease has affected gray matter in the brain can identify those at-risk for progression of disability.

People with autism less influenced by gut instincts

People with autism-related disorders are less likely to make irrational decisions, and are less influenced by gut instincts, according to research funded by the Wellcome Trust. The study adds to the growing body of research implicating altered emotional processing in autism.

Methamphetamine enters brain quickly and lingers

Using positron emission tomography (PET) to track tracer doses of methamphetamine in humans' brains, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory find that the addictive and long-lasting effects of this increasingly prevalent drug can be explained in part by its pharmacokinetics - the rate at which it enters and clears the brain, and its distribution.

Neuroimaging links chronic insomnia to reversible cognitive deficits without changes in behavior

A neuroimaging study in the Sept. 1 issue of the journal Sleep is the first to find that cognitive processes related to verbal fluency are compromised in people with insomnia despite the absence of a behavioral deficit. These specific brain function alterations can be reversed, however, through non-pharmacological treatment with sleep therapy.

What makes the human body attractive?

A study by Dr William Brown and colleagues in Brunel University's School of Social Sciences and School of Engineering and Design, published this week in the Proceedings of the National Academy of Sciences (PNAS), has revealed an explanation for the correlation between attractiveness and bodily characteristics like height, breast size, long legs, broad shoulders or a curvy figure.

Physical fitness levels influence brain atrophy in Alzheimer's

People with early Alzheimer's disease who had better fitness ratings had less atrophy in key brain areas associated with memory, according to research reported today at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease (ICAD 2008) in Chicago.

Amyloid plaques seen with conventional MRI in animal model for first time

For the first time, scientists have captured images of brain lesions similar to those found in Alzheimer's disease using clinical-grade MRI in an animal model of the disease, according to research reported at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008), in Chicago.

A baby's smile gives mothers a natural high

Scientists say the baby's smile that brightens a mother day also lights up a part of her brain.

Radioactive "tag" added to formaldehyde helps monitor body chemistry, disease

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a simple, fast method for adding a radioactive "tag" to formaldehyde, a common organic chemical.

New comprehensive map of brain connections

An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex -- the outer layer of the brain responsible for higher level thinking -- connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to the workings of both hemispheres of the brain.

Automated magnetic resonance imaging technique assists in earlier Alzheimer's diagnosis

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

Unique brain maps to assist surgery and research

Researchers from the Howard Florey Institute in Melbourne are developing new technology to create individualised brain maps that will revolutionise diagnosis of disease and enhance the accuracy of brain surgery.

People with tune deafness able to detect a wrong note unconsciously

People with tune deafness aren't able to tell when a musician accidentally strikes the wrong note in a song, but their brains know the difference. Researchers from the National Institute on Deafness and Other Communication Disorders (NIDCD), part of the National Institutes of Health, have found that people with tune deafness, an auditory processing disorder in which a person with normal hearing has trouble distinguishing notes in a melody, are able to detect a wrong note unconsciously.

Bipolar disorder in adolescents is a huge risk factor for smoking and substance abuse

A study from the Massachusetts General Hospital (MGH) supports previous reports that adolescents with bipolar disorder are at increased risk for smoking and substance abuse.

Researchers find link between altered dopamine activity and social anxiety disorder

Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction.
