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.

Viagra and Levitra ED drugs shown to allow more chemo to reach brain tumors

In a study using laboratory animals, researchers found that medications commonly prescribed for erectile dysfunction opened a mechanism called the blood-brain tumor barrier and increased delivery of cancer-fighting drugs to malignant brain tumors.

Hormone deprivation therapy - used for prostate cancer - may cause recall and concentration problems

A recent review of the literature has found that hormone deprivation therapy, a commonly used treatment for prostate cancer, may have subtle adverse effects on cognition in patients--such as in the ability to recall and concentrate.

New Alzheimer's studies show advances against different treatment targets

Two studies related to experimental Alzheimer's therapies reported positive results today at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease (ICAD 2008) in Chicago.

How anti-depressants and cocaine interact with brain

In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies for a host of psychiatric diseases, most notably in the area of addiction.

Oxytocin hormone plays role in social bonding and maternal behaviors

Oxytocin was originally studied as the "milk let-down factor," i.e., a hormone that was necessary for breast-feeding. However, there is increasing evidence that this hormone also plays an important role in social bonding and maternal behaviors.

Exercise shown to slow down Alzheimer's progress

According to a new study, patients with the early signs of Alzheimer's disease had less deterioration in the areas of the brain which control memory, if they exercised regularly.

Research on pre-eclampsia in mice may have important implications for humans

In a new March of Dimes-funded study of pre-eclampsia, a serious and potentially deadly disorder that affects about 5 percent of pregnancies, researchers have found results in mice that may have important implications for diagnosis and treatment in humans.

Physical fitness levels influence brain atrophy in Alzheimer's

People with early Alzheimer's disease who had better fitness ratings had less atrophy in key brain areas associated with memory, according to research reported today at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease (ICAD 2008) in Chicago.

Amyloid plaques seen with conventional MRI in animal model for first time

For the first time, scientists have captured images of brain lesions similar to those found in Alzheimer's disease using clinical-grade MRI in an animal model of the disease, according to research reported at the Alzheimer's Association's 2008 International Conference on Alzheimer's Disease (ICAD 2008), in Chicago.

Antimicrobial sutures reduce infections in brain shunt surgery

Children born with hydrocephalus, or "water on the brain" must have shunts implanted to drain the fluid away from the brain to reduce harmful pressure.

Tethered bilayer membrane may unlock secrets of early-stage Alzheimer's

Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a neuron's structure and function.

Research sheds light on neural mechanisms responsible for social difficulties in autism

Picking up on innuendo and social cues is a central component of engaging in conversation, but people with autism often struggle to determine another person's intentions in a social interaction.

The brain under pressure: Bristol Neuroscience attracts BBSRC grant

The Biotechnology and Biological Sciences Research Council (BBSRC) has awarded a grant of over £0.5 million to groups in the Laboratories for Integrative Neuroscience and Endocrinology and the MRC Centre for Synaptic Plasticity (project leader, Professor Kei Cho). The funding will support research into how brain cells maintain their performance, and create memories, during periods of acute stress.

Detox diet causes woman serious brain damage

A woman in Britain who suffered brain damage after following a "detox" diet has been awarded more than £800,000 in an 'out-of-court' settlement.

Use of rheumatoid arthritis drug to treat Alzheimer's causes concern

New research into the treatment of Alzheimer's disease using a popular rheumatoid arthritis drug has caused some concern.

Discovery of cells for spinal-cord repair

A researcher at MIT's Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries.

Discovery of new anatomical path through which the brain and spleen communicate

In a major step in understanding how the nervous system and the immune system interact, scientists at The Feinstein Institute for Medical Research have identified a new anatomical path through which the brain and the spleen communicate.

Study shows promising results in deep brain stimulation for treatment-resistant depression

New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced continued and sustained improvement over time.
