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.

Costs due to complications from preterm birth are staggering

In Canada, outlays for specialized care of surviving preterm infants are estimated to be almost $2 billion per year.

Breakthrough research finds genes which may help smoking cessation

Scientists supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, have for the first time identified genes that might increase a person's ability to abstain from smoking.

New insights into melatonin production

In the April 1 issue of G&D, a Korean research team led by Dr. Kyong-Tai Kim (Pohang University) describes how melatonin production is coordinated with the body's natural sleep/wake cycles.

Precise region in the frontal cortex may be specialised for learning social information

Is there a specific memory for events involving people Researchers in the Vulnerability, Adaptation and Psychopathology Laboratory (CNRS/University Paris VI France ) and a Canadian team at Douglas Hospital, McGill University (Montreal), have identified the internal part of the prefrontal cortex as being the key structure for memorising social information.

New target for removing unwanted ammonia from the body

Thousands of people with liver and kidney disease die every year from too much ammonia in their blood, and scientists from the United States and Japan have found a possible solution.

Traumatic memories can be wiped out

French CNRS scientists in collaboration have shown that a memory of a traumatic event can be wiped out, although other, associated recollections remain intact.

Regenerative medicine project taps into human stem cells

Researchers at the McKnight Brain Institute of the University of Florida have initiated a project to treat human brain and other diseases by plundering the secrets of regeneration from creatures with remarkable powers of self-renewal, such as salamanders, newts, starfish and flatworms.

Playing in the dirt to counter depression

Treatment of mice with a "friendly" bacteria, normally found in the soil, altered their behavior in a way similar to that produced by antidepressant drugs, reports research published in the latest issue of Neuroscience.

FDA approves Ceprotin to treat severe congenital protein C deficiency

The U.S. Food and Drug Administration (FDA) today licensed Ceprotin, the first biologic treatment for patients with a rare genetic defect that can cause a potentially life-threatening clotting disorder.

Arthritis pain processed in parts of brain concerned with emotions and fear

Researchers at The University of Manchester have discovered that arthritis pain, unlike that induced as part of an experiment, is processed in the parts of the brain concerned with emotions and fear.

Molecular mechanism involved in development of schizophrenia

In studying the postmortem brain tissue of adults who had been diagnosed with schizophrenia, the researchers found that levels of certain gene-regulating molecules called microRNAs were lower among schizophrenia patients than in persons who were free of psychiatric illness.

Brain's immune system plays protective role in early Alzheimer's disease

The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder.

Role of emotions in how patients feel arthritis pain

How does the brain process the experience of pain? Thanks to advances in neuroimaging, we now know the answer lies in a network of brain structures called the pain matrix.

Glimpse into early brain development shows how nerve cells move into position

Tucked into the lower, rear portion of the brain, the cerebellum plays key roles in motor learning, motor memory and sensory perception. It's also where the majority of metastatic childhood brain tumors are located. Yet scientists still know very little about its early growth.

Researchers look at whether creatine slows progression of Parkinson's disease

Researchers at the University of Rochester Medical Center are leading one of the largest clinical trials ever for Parkinson's disease.

Circadian genes may be involved in bipolar disorder

Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found.

Stanford brain tumor vaccine to be tested nationally

When Susan Wright learned that she had a type of fatal, rapidly growing brain cancer at age 46, her doctors at the University of Florida told her she wouldn't live more than 18 months.

Creatine may help Parkinson's patients by giving an energy boost to dying cells

Whether a supplement used by athletes to boost energy levels and build muscle can slow progression of Parkinson's disease is the focus of a North American study.

Root of dyscalculia found

Scientists led by UCL (University College London) have induced dyscalculia in subjects without the maths learning difficulty for the first time. The study, which finds that the right parietal lobe is responsible for dyscalculia, potentially has implications for diagnosis and management through remedial teaching.

Treating sleep apnea with continuous positive airway pressure reduces incidence of stroke

Patients with moderate to severe sleep apnea who have significantly higher serum levels of inflammatory markers that serve as precursors to coronary artery disease, as well as lesions associated with silent brain infarction, have an elevated risk of stroke, according to a group of Japanese medical researchers.
