Brain function of earthquake survivors gets acutely affected

Washington, Sep 1 (ANI): The earthquake that jolted Wenchuan, China, in 2008 has had an acute impact on the brain function of physically healthy survivors, and even poses a risk to their mental health, according a new research.

Working with collaborators from universities in China, the US and Liverpool, researchers at the Institute of Psychiatry focussed [...]

Same neural networks in brain process familiar and newly learnt words

Washington, August 29 (ANI): A series of experiments conducted as part of the Academy of Finland’s Neuroscience Research Programme (NEURO) have shown that the brain uses the same neural networks to process both familiar and newly learnt words.

In one experiment, participants learnt the name and/or purpose of 150 ancient tools. They had never heard those [...]

Why sleep deprivation affects some people more than others

Washington, June 25 (ANI): Conducting a new imaging research, scientists have explained why sleep deprivation affects some people more than others.

Researchers observed that people who are genetically vulnerable to sleep loss showed reduced brain activity after staying awake all night, while those who are genetically resilient showed expanded brain activity.

The findings help explain individual [...]

Mouse model may pave way for better anti-depressant treatments

Washington, May 28 (ANI): Using a new experimental mouse model of depression/anxiety, scientists have found that the anti-depressant effects of drugs like Prozac involve both neurogenesis-dependent and -independent mechanisms.

The finding could lead to [...]

Indian American helps develop software for early Alzhemier diagnosis

New York, May 25 (IANS) Analysis of the brain’s MRI studies, combined with a new software program, developed by a team led by an Indian American, may permit clinicians to track and diagnose Alzheimer’s disease at an early stage.
Developed by a Massachusetts General Hospital (MGH) team, the software can accurately differentiate patients with milder versions [...]

Now, software to analyse MR images and identify early Alzheimer’s disease

Washington, May 22 (ANI): Scientists at Massachusetts General Hospital (MGH) claim that they have developed a piece of software that can prove helpful in analysing MRI studies of the brain and allow diagnosis of Alzheimer’s disease and of mild cognitive impairment, a lesser [...]

Intake of methamphetamine during pregnancy can lead to brain abnormalities in the children

Recent study has shown that intake of methamphetamine during pregnancy can lead to brain abnormalities in children. Methamphetamine is a highly addictive stimulant that is injected, snorted, smoked or swallowed by the people.
Research team led by Dr. Linda Chang of the University of Hawaii compared data collected from 29 3- and 4-year-olds whose mothers used [...]

Prenatal meth exposure ’causes abnormal brain development in kids’

Washington, April 16 (ANI): Using a drug called methamphetamine during pregnancy can cause abnormal brain development in children, says a new study.

This study is the first of its kind to examine the effects of methamphetamine use during pregnancy.

“Methamphetamine use is an increasing problem among women of childbearing age, leading to an increasing number of [...]

Hormone replacement therapy ’shrinks’ brain

Washington, Jan 13 (ANI): Hormone replacement therapy may lead to brain shrinkage in postmenopausal women, say researchers.
The study showed that volumes of brain lesions were not significantly increased among women prescribed hormone therapy, but that the total olumes of brain tissue in regions critical to memory were slightly smaller.
The research team found that women who [...]
