Inherited brain activity predicts childhood anxiety risk
Inherited brain activity predicts childhood risk for anxiety – A new study focused on anxiety and brain activity pinpoints the brain regions that are relevant to developing childhood anxiety.
Brain
In animals, the brain (enkephale) (Greek for “in the skull”), is the control center of the central nervous system, responsible for behavior. The brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, equilibrioception (balance), sense of taste, and olfaction (smell).
Molecular mechanism triggering Parkinson’s disease identified
Molecular mechanism triggering Parkinson’s disease identified in Stanford study – Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson’s disease. This discovery not only may explain how a genetic mutation linked to Parkinson’s causes the cells’ death, but could also open the door to new therapeutic approaches for the malady.

Depression may double risk of dementia & Alzheimer’s disease
Depression May Nearly Double Risk of Dementia – A new study shows that having depression may nearly double your risk of developing dementia later in life, revealed in a research published in the July 6, 2010, issue of Neurology.
Brain imaging findings in Alzheimer’s disease associated with genetic factors
Study evaluates association of genetic factors and brain imaging findings in Alzheimer’s disease – By investigating the association between genetic loci related to Alzheimer’s disease and neuroimaging measures related to disease risk, researchers may have uncovered additional evidence that several previously studied genetic variants are associated with the development and progression of Alzheimer’s disease and also may have identified new genetic risk factors for further study, according to a report in the June issue of Archives of Neurology, one of the JAMA/Archives journals.
Mutations in presenilin gene may cause early onset Alzheimer’s disease
Researchers discover how mutations in presenilin gene cause early onset Alzheimer’s disease — Findings could pave the way for novel treatments – Researchers have discovered how mutations in the presenilin 1 gene cause early-onset Alzheimer’s disease (AD). The finding is reported online in the journal Cell.
Genetic variants may make people susceptible to autism disorder
Autism genome project identifies genetic variants that may make people susceptible to disorder – Autism is caused in part by rare genetic changes called copy number variants (CNVs), revealed by an international consortium of researchers from more than 70 universities, including the University of Utah.
Tobacco companies challenged anti smoking signs in US
Philip Morris, Lorillard and R J Reynolds have challenged antismoking signs in New York, USA. – In US, 3 tobacco companies Philip Morris, Lorillard and R. J. Reynolds, and trade associations have challenged antismoking graphic images of diseased brains, lungs and teeth.
Deep brain stimulation is an effective treatment for Parkinson’s disease
Deep brain stimulation at 2 different targets gives similar motor benefits in Parkinson’s disease – Studies have shown that a “brain pacemaker” called deep brain stimulation (DBS) is an effective treatment for Parkinson’s disease.
New target for antidepressants for depression and anxiety
Animal study reveals new target for antidepressants – University of Michigan scientists have provided the most detailed picture yet of a key receptor in the brain that influences the effectiveness of serotonin-related antidepressants, such as Prozac.
Acupuncture’s molecular effects pinned down
Acupuncture’s molecular effects pinned down — New insights spur effort to boost treatment’s impact significantly – Scientists have taken another important step toward understanding just how sticking needles into the body can ease pain. In a paper published online May_30 in Nature Neuroscience, a team at the University of Rochester Medical Center identifies the molecule adenosine as a central player in parlaying some of the effects of acupuncture in the body.
Early clamping may interrupt humankind’s first natural stem cell transplant
Do we clamp the umbilical cord too soon? — USF researchers: Early clamping may interrupt humankind’s first ‘natural stem cell transplant’ – The timing of umbilical cord clamping at birth should be delayed just a few minutes longer, suggest researchers at the University of South Florida’s Center of Excellence for Aging and Brain Repair.
