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.

Nitrogen balance occurs with a precise 24-hour rhythm in mammals

Researchers at Case Western Reserve University School of Medicine demonstrated that nitrogen balance, the process of utilizing amino acids and disposing of their toxic byproducts, occurs with a precise 24-hour rhythm - also known as circadian rhythm - in mammals. Disruption of this cycle has a direct impact on survival of organisms, and may predispose one to life altering diseases including diabetes and cardiovascular disease.

First study to demonstrate cost-effectiveness of intensive TBI care

Aggressive treatment for severe traumatic brain injuries costs more than routine care, yet yields significantly better outcomes, improved quality of life, and lower long term care costs, according to a new study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Bevacizumab drug improves cardiac output in patients with HHT

In a small study that included 25 patients with hereditary hemorrhagic telangiectasia (a genetic disorder that leads to abnormalities of blood vessels) and severe liver involvement with this disease, patients who received the drug bevacizumab had improved cardiac output and a reduction in the duration and number of episodes of nose bleeds, a potentially life-threatening complication for patients with this disorder, according to a study in the March 7 issue of JAMA.

Aggressive treatment of severe TBI is cost-effective: Study

Researchers at the Perelman School of Medicine at the University of Pennsylvania have demonstrated that aggressive treatment of severe traumatic brain injury, which includes invasive monitoring of intracranial pressure (ICP) and decompressive craniectomy, produces better patient outcomes than less aggressive measures and is cost-effective in patients no matter their age--even in patients 80 years of age.

Study: Weekend smoking linked with memory damage

People who smoke only at weekends cause as much damage to their memory as those who smoke on a daily basis, according to research from Northumbria University.

SSRIs appear to reduce depressive symptoms, fetal head growth during pregnancy

Treating pregnant women with selective serotonin reuptake inhibitors (SSRIs) appears to be associated with fewer depressive symptoms, reduced fetal head growth and a higher risk for preterm birth, but not with a delay in fetal body growth, according to a report published Online First by Archives of General Psychiatry, one of the JAMA/Archives journals.

New AD marker can predict mental decline

A new marker of Alzheimer's disease can predict how rapidly a patient's memory and other mental abilities will decline after the disorder is diagnosed, researchers at Washington University School of Medicine in St. Louis have found.

Study shows how new information is encoded into prefrontal cortex

The brain has a remarkable ability to learn new cognitive tasks while maintaining previously acquired knowledge about various functions necessary for everyday life. But exactly how new information is incorporated into brain systems that control cognitive functions has remained a mystery.

Left hemisphere of the brain plays a critical role in creative thinking

It takes two to tango. Two hemispheres of your brain, that is. USC researchers are working to pin down the exact source of creativity in the brain - and have found that the left hemisphere of your brain, thought to be the logic and math portion, actually plays a critical role in creative thinking.

Gamma Knife vs. craniotomy to treat epilepsy

For about 25 percent of patients suffering from epilepsy, medications do not effectively control the disease and stop seizures. For some, epilepsy surgery is the best answer. In the past, epilepsy surgery meant a craniotomy, which requires a surgeon to open the patient's skull to remove the brain lesion causing epilepsy.

Persistent postconcussion symptoms more likely in children with TBIs

Children with mild traumatic brain injuries appear more likely to have persistent postconcussion symptoms, including cognitive complaints such as inattention and forgetfulness, which can affect quality of life, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.

MicroRNAs key to memory and learning process

Studying tiny bits of genetic material that control protein formation in the brain, Johns Hopkins scientists say they have new clues to how memories are made and how drugs might someday be used to stop disruptions in the process that lead to mental illness and brain wasting diseases.

Snoring toddlers may develop behavioural problems later: Study

A new study shows that babies and toddlers who snore, gasp for breath, or breathe with their mouth open while sleeping may be at a greater risk of behavioural problems all the way through second grade.

Antidepressants in pregnancy: weighing benefits and risks

There has been a debate on the use of antidepressant medication in pregnant women. Depression during pregnancy is, of course, difficult for the woman. In addition, depression that continues in the postpartum period may interfere with caretaking and bonding with the newborn.

New depression treatment “safe and effective”

Stimulating the brain with a weak electrical current is a safe and effective treatment for depression and could have other surprise benefits for the body and mind, a major Australian study of transcranial Direct Current Stimulation (tDCS) has found.
