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.

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.

FDA approves Soliris (eculizumab), first treatment for paroxysmal nocturnal hemoglobinuria

The U.S. Food and Drug Administration (FDA) has approved Soliris (eculizumab), the first product for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare type of blood disorder that can lead to disability and premature death.

15,595 meningitis cases this season in Africa

Two months into the dry season in the African "Meningitis Belt", 15,595 cases including 1,670 deaths have been reported to the World Health Organization (WHO) from four countries: Burkina Faso, the Democratic Republic of the Congo, Sudan and Uganda.

Generalist genes responsible for a wide range of learning disorders

According to a review in the premier issue of Mind, Brain, and Education, the latest research into learning disabilities suggests that 'generalist' genes are responsible for a wide range of learning disorders.

Protein duo maintains communication among nerves

Frustration gave way to satisfaction when an experiment that seemed to foil St. Jude researchers actually brought them a step closer to understanding how the brain maintains healthy lines of communications among its nerves.

Discovery of new cell involved with cancer

Scientists have discovered a new type of cell that appears to play a role in the development of cancer – a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.

Chemical cues turn embryonic stem cells into cerebellar neurons

Embryonic stem cells have shown a great deal of promise for alleviating heart disease and regenerating organs. But for some of the conditions for which people hold out the most hope - Alzheimer's and Parkinson's, for example - there's been little evidence to date that stem cells can work.
