Genes predict the brain's reaction to smoking

Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. A study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows that people with genetically fast nicotine metabolism have a significantly greater brain response to smoking cues than those with slow nicotine metabolism.

Study may spur research into multi-model imaging based biomarker development for AD

Alzheimer's disease (AD) is one of the most common brain disorders, with an estimated 35 million people affected worldwide. In the last decade, research has advanced our understanding of how AD affects the brain. However, diagnosis continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin. In a supplement to the Journal of Alzheimer's Disease, investigators report on the development of imaging-based biomarkers that will have an impact on diagnosis before the disease process is set in motion.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

Combination of two stress hormones shuts down brain activity for goal-directed behaviour

Cognition psychologists at the Ruhr-Universit-t together with colleagues from the University Hospital Bergmannsheil (Prof. Dr. Martin Tegenthoff) have discovered why stressed persons are more likely to lapse back into habits than to behave goal-directed. The team of PD Dr. Lars Schwabe and Prof. Dr. Oliver Wolf from the Institute for Cognitive Neuroscience have mimicked a stress situation in the body using drugs.

Mobile Music Touch may improve motor skills, sensation for people with paralyzing SCI

Georgia Tech researchers have created a wireless, musical glove that may improve sensation and motor skills for people with paralyzing spinal cord injury (SCI).

TPJ in brain carries information for decisions during social interactions

Although many areas of the human brain are devoted to social tasks like detecting another person nearby, a new study has found that one small region carries information only for decisions during social interactions. Specifically, the area is active when we encounter a worthy opponent and decide whether to deceive them.

New volumetric functional MRI scan figures out beneficiaries of chemotherapy in liver cancer patients

Studies on some 55 U.S. men and women with potentially deadly liver or pancreatic cancers show that specialized MRI scans can tell within a month whether highly toxic chemotherapy is working and killing tumor cells long before tumors actually shrink - or fail to shrink.

Researchers identify genes that influence degeneration of the hippocampus

In a genome-wide association (GWA) study, researchers from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) have identified several genes which influence degeneration of the hippocampus, the part of the brain most associated with Alzheimer disease (AD).

New study on motor chunking

You pick up your cell phone and dial the new number of a friend. Ten numbers. One. Number. At. A. Time. Because you haven't actually typed the number before, your brain handles each button press separately, as a sequence of distinct movements.

Initial data to construct first whole-brain wiring diagram of vertebrate brain

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) reached an important milestone today, publicly releasing the first installment out of 500 terabytes of data so far collected in their pathbreaking project to construct the first whole-brain wiring diagram of a vertebrate brain, that of the mouse.

Brain can rewire even at an advanced age

"This study overturns decades-old beliefs that most of the brain is hard-wired before a critical period that ends when one is a young adult," said MPFI neuroscientist Marcel Oberlaender, PhD, first author on the paper.

Changes in sensory experience can cause massive rewiring of the brain

Despite a long-held scientific belief that much of the wiring of the brain is fixed by the time of adolescence, a new study shows that changes in sensory experience can cause massive rewiring of the brain, even as one ages. In addition, the study found that this rewiring involves fibers that supply the primary input to the cerebral cortex, the part of the brain that is responsible for sensory perception, motor control and cognition.

Pfizer announces results from Lyrica clinical studies on fibromyalgia

Pfizer Inc. announced the results of studies on Lyrica (pregabalin) capsules CV presented at the American Pain Society Annual Meeting in Honolulu.

New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

Scientists discover number of unknown brain networks linked with teen drug abuse

Why do some teenagers start smoking or experimenting with drugs-while others don't? In the largest imaging study of the human brain ever conducted-involving 1,896 14-year-olds-scientists have discovered a number of previously unknown networks that go a long way toward an answer.

First study to show SCAT2 as useful sideline tool for concussion

Princeton's Margot Putukian, MD presented "Prospective Clinical Assessment (SCAT2), Hybrid Neuropsychological Testing and Neuroimaging in the Evaluation of Sports-Related Concussions" at the 21st American Medical Society for Sports Medicine Annual Meeting in Atlanta, Ga. on April 24, 2012.

Exercise staves off dementia in older women: Study

Older women with first signs of memory decline might ward off full-blown dementia by engaging in routine strength training according to a new study. However supervised weight-lifting seems to be working better than aerobics-based activity programs, the study found. The study was conducted with researchers from the Department of Psychology and Division of Geriatric Medicine at UBC, and Department of Psychology at the University of Iowa.

Alzheimer's may spread through connected neurons

Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.

Union County Commission honors KF scientist with Women of Excellence Award

Helen Genova, PhD, research scientist at Kessler Foundation, received a Women of Excellence Award in Health Sciences from the Union County Commission on the Status of Women. In the Foundation's Neuropsychology and Neuroscience Laboratory, she investigates the effects of multiple sclerosis (MS) and traumatic brain injury on cognitive function with grant funding.
