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.

Deficiency in vitamin D may exacerbate autoimmune disease

Deficiency in vitamin D has been widely regarded as contributing to autoimmune disease, but a review appearing in Autoimmunity Reviews explains that low levels of vitamin D in patients with autoimmune disease may be a result rather than a cause of disease and that supplementing with vitamin D may actually exacerbate autoimmune disease.

Dopamine agonists trigger destructive behaviors

A new study conducted at Mayo Clinic reports that one in six patients receiving therapeutic doses of certain drugs for Parkinson's disease develops new-onset, potentially destructive behaviors, notably compulsive gambling or hypersexuality.

New common pathway in neurodegenerative disease is a possible door to a point of no return

A just-out study suggests that what keeps chronic nervous system diseases such as Alzheimer's, Huntington's and ALS going - until they overcome the internal protective mechanisms a body can throw at them - may largely come down to poor conversational skills.

Health problems associated with Chinese slimming capsules

Taking herbal food supplements is certainly not free of risk. Since 2005, the poison emergency centers in the German cities of Freiburg and Gottingen have registered a total of 17 patients with health problems after taking Chinese slimming capsules.

Discovery of marker for colon stem cells could shed light on tumor growth

Cancer researchers led by Bruce Boman, M.D., Ph.D. director of Cancer Genetics and Stem Cell Biology at the Helen F. Graham Cancer Center of the Christiana Care Health System, and a faculty member at the University of Delaware, have discovered an enzyme common to both normal and malignant colon stem cells that will assist scientists searching for a cure for colon cancer.

Genetic variation found to increase risk of schizophrenia

Rutgers geneticist Linda Brzustowicz and her colleagues have identified a specific DNA change that is likely to increase risk for developing schizophrenia in some people.

$Adult brain processes fractions easier than child's$

Adult brain processes fractions easier than child's

Although fractions are thought to be a difficult mathematical concept to learn, the adult brain encodes them automatically without conscious thought, according to new research in the April 8 issue of The Journal of Neuroscience.

Rogue Alzheimer's gene causes early brain changes

British scientists have found that some young adults who carry a certain genetic variant have an increased risk of developing Alzheimer's disease and distinct brain patterns and changes in their brain activity started decades before any symptoms appeared.

New, simple method identifies preterm infants at risk of eye disease

A simple way of establishing which preterm infants are at risk of developing the eye disease ROP is to follow their weight gain. A new study from the Sahlgrenska Academy, University of Gothenburg, Sweden, suggests that following weekly weight development might replace the need for considerably more expensive ophthalmological examinations.

Young adults at future risk of Alzheimer's have different brain activity

Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise, according to a new brain imaging study by scientists from the University of Oxford and Imperial College London.

Researchers regenerate axons necessary for voluntary movement

For the first time, researchers have clearly shown regeneration of a critical type of nerve fiber that travels between the brain and the spinal cord and which is required for voluntary movement.

How the retina works: Like a multi-layered jigsaw puzzle of receptive fields

About 1.25 million neurons in the retina -- each of which views the world only through a small jagged window called a receptive field -- collectively form the seamless picture we rely on to navigate our environment.

Researchers aim to determine if specific brain circuits and pathways might be responsible for wisdom

Researchers at the University of California, San Diego School of Medicine have compiled the first-ever review of the neurobiology of wisdom – once the sole province of religion and philosophy.

Schizophrenics appear to rely considerably less on top-down processing during perception

Patients with schizophrenia are able to correctly see through an illusion known as the 'hollow mask' illusion, probably because their brain disconnects 'what the eyes see' from what 'the brain thinks it is seeing', according to a joint UK and German study published in the journal NeuroImage.
