Continuous exposure to a negative event may neutralize its ability to impact one's mood, according to research conducted at Tel Aviv University's School of Psychological Sciences. The study, published in Attention, Perception, & Psychophysics, used the "emotional Stroop task" to measure the effect of repeated negativity to an individual.
Cancer researchers say they have created a new and easier technique to diagnose brain tumors in just a half hour. Traditionally, testing for brain tumors require intrusive surgery to acquire a tissue sample for testing that can take two to three days to complete. The new method is a simple blood test that yields results much quicker and allows the patient to avoid both the physical trauma.
Head injuries can bring about significant changes in the brain after concussion symptoms have faded, according to research conducted at the Mind Research Network and University of New Mexico School of Medicine. The study, published in the journal neurology, analyzed 100 subjects - 50 of whom had suffered a mild concussion and 50 who hadn't.
Those who live through an economic recession may face a greater risk of cognitive decline in old age, according to research conducted at the University of Luxembourg. The study, published in the Journal of Epidemiology and Community Health, analyzed data from 12,000 people aged 50 and older in 11 countries.
A new cognitive model based on the reading of cognitive test scores may help correctly diagnose early signs of Alzheimer's, according to researchers at Johns Hopkins. The study, published in the journal Neuropsychology, looked at the records of over 500 subjects (aged 60 and older) given cognitive testing for the disorder.
Different neurons in the brain could be responsible for triggering different kinds of fear, according to researchers at the European Molecular Biology Laboratory in Italy. Researchers examined the brain activity of mice as they were exposed to different types of fear. Those fears including physical harm, fear of other animals and fear of more aggressive animals within their own species.
New research is showing that individuals who have high blood pressure are more susceptible to having biomarkers of Alzheimer's disease in their spinal fluid. According to the Mayo Clinic, individuals suffering from high pulse pressure could be an indicator of heart problems with older adults. The study was published in the journal "Neurology."
Nostalgic memories of the past could make some people feel more positive about their prospects for the future, according to researchers from University of Southampton in the UK. Researchers surveyed a group of volunteers on their self-perception after hearing a nostalgic holiday song or story. They found that those who heard a nostalgic song were more likely to report optimistic feelings.
Some symptoms associated with Parkinson's disease could be brought on by a particular kind of fungus, according to researchers at Rutgers University in New Jersey and Emory University in Georgia.

Learning to speak a second language could help delay the onset of dementia, according to a new study from researchers at the University of Edinburgh in the UK and Nizam's Institute of Medical Sciences in Hyderabad, India. Researchers examined 648 dementia patients living in India. Two hundred and forty of the patients had previously been diagnosed with Alzheimer's disease.
Personal reflection during depressive episodes can trigger increases in brain activity, according to research conducted at the University of Liverpool. The study, published in PLOS One, used MRIs to read the brains of 13 severely depressed individuals. The subjects used positive, negative or neutral adjectives to describe themselves or the British Queen, an impersonal object.
Early music training may prove beneficial to the brain throughout later life - even when practice of the instrument is forgone, according to research conducted at Northwestern University. The study, published in the Journal of Neuroscience, argued that learning an instrument changes the anatomy and function of the brain.
A common molecule in the brain holds the key to overcoming jet lag more quickly, according to a study from researchers at Washington University in St. Louis. Researchers examined the effects of brain molecules called VIPs (vasoactive intestinal polypeptides), which regulate the internal clock in the brain.
Human faces may appear more attractive when seen in groups, according to a new study from researchers at the University of California. For the study the researchers carried out five separate experiments on a pool of 130 undergrads. In the experiments, the students were shown photos with groups of 100 or more people. They were asked to rate the attractiveness of individuals with those photos.
