The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Lack of association between Rh status, Rh immune globulin in pregnancy and autism

The increase in the number of diagnosed cases of autism in recent years has sparked concern that environmental toxins may cause this complex disorder.

Some children who are born deaf recover from their deafness

There are two causes of congenital deafness among children. One is the lack of hair cells, receptors in the inner ear that convert sounds into pulse signals that activate the auditory nerve.

Clearer view of synaptic plasticity

Scientists are keenly studying how neurons form synapses--the physical and chemical connections between neurons--and the "pruning" of neural circuits during development, not least because synaptic abnormalities may partially underlie many developmental and neurodegenerative diseases.

Implanting dopamine generators in brain cells improves Parkinson's in monkeys

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 Mar'a Rosario Luquin Piudo, neurologist at the Hospital and at the other Navarra University-based medical centre, CIMA (the Research Centre for Applied Medicine).

Possible neuroprotective effect of testosterone treatment in men

A small pilot study suggests that testosterone treatment is safe, well tolerated and may reduce symptoms, slow brain degeneration and increase muscle mass in men with relapsing-remitting multiple sclerosis, the most common form of the disease, according to a report in the May issue of Archives of Neurology, one of the JAMA/Archives journals.

Study revises dynamin's role in nerve cell function

An unexpected finding on how nerve cells signal to one another could rewrite the textbooks on neuroscience, says a collaborative team of researchers at Weill Cornell Medical College and Yale University.

Testosterone gel helps men multiple sclerosis

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.

Cedars-Sinai helps Doug Fieger battle brain tumors

When singer/songwriter/guitarist Doug Fieger, lead singer of The Knack, found out last year that he had two brain tumors, he was concerned that either the tumors or the side effects of surgery would leave him unable to pursue his livelihood.

Chemical maps hint at drug's effects on schizophrenia

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.

Study looks at traumatic brain injury - leading cause of abusive death in children

Confronted with the same hypothetical scenarios of traumatic brain injuries to children, pediatricians and pathologists were unable to agree half the time whether the deaths should be investigated as potential child abuse, researchers at Indiana University School of Medicine found.

The Phi Complex as a neuromarker of human social coordination

Researchers from Florida Atlantic University (FAU) have been able to identify neural signatures of effective, real-time coordination between people in one of the first studies in the field of social neuroscience to actually record, measure and analyze both behavior and brain activity simultaneously in two interacting humans.

Fictive learning may play a role in addiction

"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 in the Proceedings of the National Academy of Sciences.
