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.

Next generation of effective viral-based therapies for cancer

Researchers at Columbia University Medical Center continue to make strides in their work to develop the next generation of effective viral-based therapies for cancer.

First clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus

An international team of medical experts led by a Virginia Commonwealth University researcher has established the first clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus, a debilitating condition in the brain that often goes undiagnosed or is misdiagnosed as Alzheimer's or Parkinson's disease.

Failure to block out inappropriate sensory stimulation activity in Alzheimer disease

Some people close their eyes when they listen to music, others wear earplugs when they read in noisy places. Both serve to block out inappropriate sensory stimulation, something that happens automatically when we concentrate.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.

Heavy alcohol consumption can significantly increase men's risk of developing atrial fibrillation

A large-scale study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) has found that heavy alcohol consumption - 35 or more drinks per week -- can significantly increase men's risk of developing atrial fibrillation, a dangerous type of arrhythmia and one of the leading risk factors for stroke.

Green tea may protect the brain against Alzheimer's disease

Researchers at the University of South Florida (USF) have found that green tea may offer another potential health benefit - protecting the brain against the ravages of Alzheimer's disease.

SARS can infiltrate brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problems, according to an article in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Blood test to measure hormone prolactin can help determine type of seizure

Using a blood test to measure the level of the hormone prolactin can help determine, in certain clinical settings, whether an epileptic seizure has occurred, according to a guideline developed by the American Academy of Neurology and published in the September 13, 2005 issue of Neurology.

Link between CAPON gene and schizophrenia

We have known for a long time that there is a genetic component to schizophrenia, but nailing down the gene(s) has not been easy.

Phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of brain

Yale researchers report the first evidence that phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of the brain that can be suppressed with specially designed molecular agents.

Pocket-size device helps people living with HIV remember their medicine

In a study from Johns Hopkins, a pocket-size device giving electronic-voice reminders to "take your medicine" proves to be a success for people living with HIV whose memory is slightly impaired by the virus.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

Prions rapidly 'remodel' good protein into bad

Two Brown Medical School biologists have figured out the fate of healthy protein when it comes in contact with the infectious prion form in yeast: The protein converts to the prion form, rendering it infectious. In an instant, good protein goes bad.

Can we reverse mental declines? Well, for most of us, the answer is yes

As we get beyond retirement age, most of us will not be as mentally sharp as we once were. But a researcher at the University of Alberta says most people have the ability to reverse the mental declines that come with aging.

First large-scale whole genome map of genetic variability associated with Parkinson's disease

Mayo Clinic researchers in collaboration with scientists at Perlegen Sciences, Inc. and funded by the Michael J. Fox Foundation for Parkinson's Research have produced the first large-scale whole genome map of genetic variability associated with Parkinson's disease.

Researchers selectively knock out memory associations connected with receiving cocaine

Addicts crave drugs and suffer relapse not just because of the alluring high of drugs, but also because they are compelled by the powerful, haunting memory associations with the environment surrounding their drug taking. Thus, treatments that could eliminate those memory associations could prove effective in treating addiction, researchers believe.

Finding may significantly broaden understanding of how the brain selects and retains information

By examining how sounds are registered during the process of learning, UC Irvine neurobiologists have discovered a neural coding mechanism that the brain relies upon to register the intensity of memories based on the importance of the experience.

Microtubules critical to development of mental disorders

Neuroscientists at the University at Buffalo have shown in two recently published papers that destabilization of structures called microtubules, intracellular highways that transport receptors to their working sites in the brain, likely underlie many mental disorders and could be promising targets for intervention.

Children who survive cancer face educational difficulties and social isolation

A new study finds children who survive cancer have about twice the rate of educational and social problems compared to children without a history of cancer.

HOXA1 is a gene that's been looking for a disorder for a long time

Researchers at Children's Hospital Boston, who specialize in studying the genetics of rare eye-movement disorders, have found a rare genetic syndrome whose implications go far beyond the eye, raising intriguing questions about human cardiovascular and brain development.
