Implanting dopamine generators (dopaminergics) in brain cells has produced improvement in the symptoms in Parkinson's, according to the results of tests carried out with monkeys by the Navarra University Hospital, led by Dr María Rosario Luquin Piudo, neurologist at the Hospital and at the other Navarra University-based medical centre, CIMA (the Research Centre for Applied Medicine).
"Hope is being given to patients with malignant and ultimately fatal spinal tumors where hope was never before available," said Dr. Isabelle Germano, Professor of Neurosurgery and Co-Director of The Radiosurgery Program at The Mount Sinai Medical Center. "All it takes is one thirty-minute out-patient treatment of pinpointed radiation and the tumor shrinks along with the pain from the cancer. Now cancer spreading to the spine doesn't mean a lifetime of pain or a wheelchair for a patient anymore."
Free will and true spontaneity exist … in fruit flies. This is what scientists report in a groundbreaking study in the May 16, 2007 issue of the open-access journal PLoS ONE.
"Animals and especially insects are usually seen as complex robots which only respond to external stimuli," says senior author Björn Brembs from the Free University Berlin. They are assumed to be input-output devices. "When scientists observe animals responding differently even to the same external stimuli, they attribute this variability to random errors in a complex brain."
A surprisingly complete fossil skull of an ancient relative of humans, apes and monkeys bears striking evidence that our remote ancestor was less mentally advanced than expected by about 29 million years ago.
A smokeless cannabis-vaporizing device delivers the same level of active therapeutic chemical and produces the same biological effect as smoking cannabis, but without the harmful toxins, according to UCSF researchers.
Hormones in children's saliva may be a biological indicator of the trauma kids undergo when they are chronically bullied by peers, according to researchers who say biological markers can aid in the early recognition and intervention of long-term psychological effects on youth.
"Bullying is mainly self-reported either by students or observed by teachers," said JoLynn V. Carney, associate professor of counselor education at Penn State.
Close on the heels of a large-scale clinical trial just underway to confirm that the female hormone estriol combats the effects of multiple sclerosis (MS) in women, a just completed pilot study at UCLA now shows promise for the use of testosterone to combat its effects in men.
Antipsychotic drugs do most of their work in the brain, but they also leave behind in the bloodstream a trail of hundreds of chemicals that may be used in the future to direct better treatment for schizophrenia and other psychiatric conditions, say Duke University Medical Center researchers.
The study is among the first to use metabolomics -- the measurement of thousands of chemical byproducts of the body's cellular processes -- to look at a psychiatric disease and its response to therapy, according to the researchers.
"What might have been" or fictive learning affects the brain and plays an important role in the choices individuals make – and may play a role in addiction, said Baylor College of Medicine researchers and others in a report that appears online today in the Proceedings of the National Academy of Sciences.
Professor of Women's Health Psychology at the University of Western Sydney, Jane Ussher, has been researching the issue for 20 years and says that women are being controlled by medical practices which position their unhappiness as a biomedical condition.
Women are being sold the idea that their bodies are biologically faulty and they need medication for PMS, post-natal depression and menopausal outbursts when in fact the pressures of being 'superwoman' are more likely to blame.
What do mutual grooming, politeness, priestly celibacy, military heroism, car insurance, and overwork have in common?
The Beatles' George Harrison wondered in his famous love song about the "something" that "attracts me like no other lover." A University at Buffalo expert explains that that "something" is actually several physical elements that -- if they occur in a certain order, at the right time and in the right place -- can result in true love.
Cerebral malaria (CM) is a severe form of malaria that affects the brain and is fatal in about 30-50% of the cases. But researchers in Portugal report a gene – Hmox1 – that protects against the disease by releasing CO into the host blood stream counteracting CM inflammatory processes (CO is known to have anti-inflammatory properties) and inhibiting the development of the infection in the brain.
Parkinson's disease is well-known for its progression of motor disorders: stiffness, slowness, tremors, difficulties walking and talking. Less well known is that Parkinson's shares other symptoms with narcolepsy, a sleep disorder characterized by sudden and uncontrollable episodes of deep sleep, severe fatigue and general sleep disorder.
When male primates tussle and females develop their social skills it leaves a permanent mark – on their brains. According to research published in the online open access journal BMC Biology, brain structures have developed due to different pressures on males and females to keep up with social or competitive demands.
An international research team consisting of Patrik Lindenfors, Charles Nunn and Robert Barton examined data on primate brain structures in relation to traits important for male competition, such as greater body mass and larger canine teeth.
