The neuroscience of musical chills

Scientists have found that the pleasurable experience of listening to music releases dopamine, a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food, drugs and sex. The new study from The Montreal Neurological Institute and Hospital - The Neuro at McGill University also reveals that even the anticipation of pleasurable music induces dopamine release [as is the case with food, drug, and sex cues].

Scientists find way to prevent early stage pancreatic cancer in research models

Cancer researchers at The Peggy and Charles Stephenson Oklahoma Cancer Center have found a way to stop early stage pancreatic cancer in research models - a result that has far-reaching implications in chemoprevention for high-risk patients.

Population of highly active neurons could provide insight into neocortex

Carnegie Mellon University researchers have found that within the brain's neocortex lies a subnetwork of highly active neurons that behave much like people in social networks.

Removal of ZIP proteins from hippocampus cell protects them from injury

Researchers in the Blue Bird Circle Developmental Neurogenetics Laboratory in the department of neurology at Baylor College of Medicine have discovered that zinc enters cells through specialized protein gates known as ZIP transporters, and removing these ZIP proteins from cells in the hippocampus significantly protects them from injury.

Scientists receive $1.4 million NSF grant to develop robotic device for heart surgery

In a truly interdisciplinary effort, a team of biomedical scientists and engineers from the University of Houston and physicians from The Methodist Hospital Research Institute are collaborating to develop a platform for image-guided and robot-assisted surgeries on beating hearts that is minimally invasive.

Toshiba announces multi-center trial to evaluate Time-SLIP Renal MR Angiography

Non-contrast MR angiography provides clear, high-quality images and can be used as an effective tool for diagnosing renal artery stenosis. To illustrate non-contrast MRA's ability as a diagnostic tool for renal artery stenosis, Toshiba has announced a multi-center trial to establish the clinical value of non-contrast Renal MRA using Time-SLIP.

Aggressive surgery for brain tumors increases survival in children

A new Mayo Clinic study found that children with low-grade brain tumors (gliomas) who undergo aggressive surgery to completely remove the tumor have an increased chance of overall survival. If complete removal is not possible, adding radiation therapy to a less complete surgery provides patients with the same outcomes as a complete removal.

Cold Spring releases new series of laboratory manuals

Sophisticated techniques that permit the visualization of dynamic processes in cells, tissues, and organ systems at extraordinary levels of resolution have become tremendously valuable in biological research. However, finding the right imaging method and optimizing it for data collection can be a daunting process, even for an established imaging laboratory. To fill this need, a new series of laboratory manuals has been developed by Cold Spring Harbor Laboratory Press. The first volume in this series, Imaging: A Laboratory Manual, has just been released.

Video game-based technologies allow new insight into memory, perception and motor control

New tools inspired by video games are revealing how the brain senses and responds to its surroundings, finds new human and animal research. Taking advantage of state-of-the art technologies to track and mimic real-life environments, these studies show with new detail how the brain navigates, identifies, and remembers a setting. In additional human research, scientists apply these same technological advances to help people who have experienced strokes regain skills.

Structural imaging techniques can help identify risk for developing Alzheimer's disease

New results from a study by neuroscientists at Rush University Medical Center suggest that people at risk of developing Alzheimer's disease exhibit a specific structural change in the brain that can be visualized by brain imaging. The findings may help identify those who would most benefit from early intervention.

New findings on HIV can help validate structure-based drug design approach

The development of new drugs to treat and prevent HIV/AIDS depends on understanding the basic biology of how the virus infects human cells. For 25 years, researchers supported primarily by NIH's National Institute of General Medical Sciences (NIGMS) have been generating the structures of key viral proteins, revealing important insights into the virus's mechanisms and, more importantly, its Achilles' heels.

tDCS electric stimulation can improve motor function in stroke patients

A noninvasive electric stimulation technique administered to both sides of the brain can help stroke patients who have lost motor skills in their hands and arms, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).

Researchers to determine levels of stroke risk in patients with narrowed brain arteries

Neurological researchers at Rush University Medical Center are part of a multicenter, National Institutes of Health (NIH) study to determine the levels of stroke risk and stroke recurrence in patients with narrowed brain arteries.

New radiotracer application may advance understanding of estrogen-related diseases

A study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has demonstrated that a molecule "tagged" with a radioactive form of carbon can be used to image aromatase, an enzyme responsible for the production of estrogen, in the human brain. The research, published in the November issue of Synapse, also uncovered that the regions of the brain where aromatase is concentrated may be unique to humans.

Study reveals a potential target for treating brain trauma

Brain damage continues to develop and evolve for months after a traumatic brain injury (TBI), revealing a potential target for treatments to improve brain trauma, new research led by the University of Melbourne, Australia has found.

Lactic acid levels in brain linked to aging process

Researchers at Karolinska Institutet have shown that they may be able to monitor the aging process in the brain, by using MRI technique to measure the brain lactic acid levels. Their findings suggest that the lactate levels increase in advance of other aging symptoms, and therefore could be used as an indicator of aging and age-related diseases of the CNS.

Molecular imaging technique pinpoints changes that take place in injured brain

Results from a study published in the November issue of The Journal of Nuclear Medicine (JNM) show that powerful imaging techniques positron emission tomography (PET) fused with magnetic resonance imaging (MRI) are helping researchers better understand the long-term functional and structural changes that take place after traumatic brain injury (TBI).
