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.

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.

Persistent protein expression may explain why tumors return after therapy in glioblastoma patients

Persistent protein expression may explain why tumors return after therapy in glioblastoma patients, according to a study published on March 5th in the Journal of Experimental Medicine.

Scientists identify gene that causes adult-onset primary cervical dystonia

Researchers have identified a gene that causes adult-onset primary cervical dystonia, an often-painful condition in which patients' necks twist involuntarily.

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.

Zalicus completes reformulated Z160 Phase 1 clinical trial for pain

Zalicus Inc. a biopharmaceutical company that discovers and develops novel treatments for patients suffering from pain and immuno-inflammatory diseases today announced the successful completion of a Phase 1 clinical trial evaluating the pharmacokinetics and safety of a new formulation of Z160, a novel oral N-type calcium channel blocker.

Inhalation of nitric oxide could help improve blood flow to ischemic brain

LMU researchers developed a new strategy for the treatment of stroke, which could help to improve blood flow to ischemic brain. Strokes are due to a localized reduction in the blood supply to the brain, mainly due to the blockage of a vessel by a blood clot.

FDA clears Covidien Solitaire FR revascularization device

Covidien, a leading global provider of healthcare products, today announced that the Solitaire FR revascularization device has been cleared by the U.S. Food and Drug Administration. The Solitaire FR device is intended to restore blood flow to the brain in patients suffering acute ischemic stroke by mechanically removing blood clots from blocked vessels.

Young children with SDB more likely to develop neurobehavioral problems

A study of more than 11,000 children followed for over six years has found that young children with sleep-disordered breathing are prone to developing behavioral difficulties such as hyperactivity and aggressiveness, as well as emotional symptoms and difficulty with peer relationships, according to researchers at Albert Einstein College of Medicine of Yeshiva University.

Brain more flexible and trainable than previously thought

Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought.

New tool to map extent of traumatic brain injury

Traumatic brain injury among soldiers, sportsmen and women and accident survivors are common but may go undetected at the time of the event and manifest later in life. Now scientists are testing a tool that lights up the breaks these injuries leave deep in the brain's wiring, much like X-rays show broken bones.

Deficits in mirror neuron system contribute to social impairments in ASD

Impaired social function is a cardinal symptom of autism spectrum disorders (ASDs). One of the brain circuits that enable us to relate to other people is the "mirror neuron" system. This brain circuit is activated when we watch other people, and allows our brains to represent the actions of others, influencing our ability to learn new tasks and to understand the intentions and experiences of other people.
