Ethical challenges ahead for neuroscience and society

Are we ready for a future where brain scans invade our private thoughts? Will we have to alter our brains chemically to keep competitive at our jobs? Could science determine that "souls" do not exist, and, if so, what does that mean for how we think of ourselves as human beings?

Prenatal alcohol exposure has effects far beyond fetal alcohol syndrome

Numerous studies have documented IQ deficits in children with fetal alcohol syndrome (FAS). Little research, however, has found IQ deficits in children with alcohol-related neurodevelopmental disorder (ARND), who generally exhibit less severe neurobehavioral deficits than children with FAS.

Brain imaging study shows brain differences between autistic boys with language impairment and those with normal language development

The study, published October 11, 2004, in the advance online issue of the Annals of Neurology, found that a language center of the brain -- Broca's area -- is apparently normal in autistic boys who have normal language capabilities.

Findings point to the hippocampus as critical to the process of recollection

For millennia, the process of memory and remembering has intrigued scholars and scientists. In 350 B.C., Aristotle, in his seminal treatise on the subject, described it as having two forms: familiarity and recollection. Of these, he considered recollection to be a purely human condition.

Organ transplant recipients infected with West Nile virus develop more severe neurological illness

West Nile virus is an infection which in the last three years has had a significant impact in the United States. The virus is spread from birds to humans via mosquito bites. Symptoms include headache, fever and disorientation, and the disease can cause serious illness in a small percentage of infected people.

Premature babies grow up to have a portion of the brain smaller than normal

Kids on a playground can be hard to tell apart. But those who were born significantly preterm may be struggling with a hidden handicap that sets them apart from their peers: specific areas of the brain that are smaller than normal, even years later.

MRI may be better than polygraph for revealing lies

A new study involving people telling lies while undergoing functional magnetic resonance imaging (fMRI) provides early indications that understanding the brain basis of deception may lead to a better lie detection method than polygraph tests.

Study helps to visualize how brain develops with age

The brain's center of reasoning and problem solving is among the last to mature, a new study graphically reveals. The decade-long magnetic resonance imaging (MRI) study of normal brain development, from ages 4 to 21, by researchers at NIH's National Institute of Mental Health (NIMH) and University of California Los Angeles (UCLA) shows that such "higher-order" brain centers, such as the prefrontal cortex, don't fully develop until young adulthood.
