Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Research findings represents a step toward understanding the machinery by which the brain processes decisions

While neurobiologists have long suspected that certain regions of the brain are specifically involved in making decisions, the challenge has been to develop rigorous laboratory behavioral experiments that could pinpoint those areas.

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.

Pilot study of mind-to-movement device shows early promise

In March 2002, Brown University researchers published an astounding piece of science. Three rhesus monkeys, they reported, could control a computer cursor without their hands. They used their minds instead.

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence

Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence than do other children their age, according to two studies funded by the National Institutes of Health (NIH). Both studies appear in the October issue of Journal of Pediatrics.

12 ferrets and a DVD suggest that the brain cranks away on tasks completely unknown to us

There’s an old myth that we only use 10 percent of our brains, but researchers at the University of Rochester have found in reality that roughly 80 percent of our cognitive power may be cranking away on tasks completely unknown to us.

Researchers identifiy brain circuit that appears crucial in converting short-term memories into long-term memories

The circuit links the major learning-related area of the brain to another region that governs the brain's higher functions.

Portion of the brain devoted to vision may play a prominent role in processing the spoken word in blind people

The findings yield important information about the brain's ability to compensate for lost function. The study appears in the October 3, 2004 online issue of Nature Neuroscience1 and in the journal's November issue.

What you see is not always what you get with binocular rivalry

It is common to say 'I can't believe my eyes' when surprised by what we see. Recent scientific evidence suggests that we have a right to be sceptical and that what we see depends in no small part on what we expect to see.

Immunoglobulins may help patients with Alzheimer’s

Immunoglobulins which are already being used to treat multiple sclerosis may also be able to help patients with Alzheimer’s. This, at least, is the finding of a pilot study on five patients at the University of Bonn.

Researchers get a grip on marijuana

Now researchers at Stanford University School of Medicine are a step closer to understanding how the drug's active ingredients - tetrahydrocannabinol and related compounds, called cannabinoids - may exert their effects.

New research into stimulus-related ear differences from birth may provide improved methods for newborn hearing tests

Researchers have known since the 1950s that humans process speech and tone sounds in different sides of the brain.

Gray matter in brain associated with language processing among people with a family history of dyslexia

Italian researchers have observed significant reductions of gray matter volume in areas of the brain associated with language processing among people with a family history of dyslexia in comparison with controls with no reading problems.

Relationship between brain chemical messenger glutamate and schizophrenia traits

Researchers at the NIH's National Institute of Mental Health (NIMH) have identified a relationship between a small section of one gene, the brain chemical messenger glutamate, and a collection of traits known to be associated with schizophrenia.

Gene responsible for management of glutamate is a promising candidate in determining risk for schizophrenia

Researchers at the National Institute of Mental Health have identified a relationship between a small section of one gene, the brain chemical messenger glutamate, and a collection of traits known to be associated with schizophrenia.

Scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning

Using a new molecular genetic technique, scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning. Without the gene, the monkeys lost their sense of balance between reward and the work required to get it, say researchers at the National Institute of Mental Health .

Scientists have tricked subjects in an experiment into believing that a rubber hand was part of their own body

The findings about the brain’s awareness of its own body will hopefully lead to better understanding of disorders of self-perception, as for example in brain-damaged patients who no longer recognise their own limbs after stroke, or amputees who still experience pain from limbs that are no longer there.
