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.

Why minor details of an episode are linked to long-term memories

Neuroscientists at MIT's Picower Institute of Learning and Memory have uncovered why relatively minor details of an episode are sometimes inexplicably linked to long-term memories. The work is slated to appear in the Jan. 13 issue of Neuron.

Banned chemicals found in pregnant women

The bodies of virtually all U.S. pregnant women carry multiple chemicals, including some banned since the 1970s and others used in common products such as non-stick cookware, processed foods and personal care products, according to a new study from UCSF. The study marks the first time that the number of chemicals to which pregnant women are exposed has been counted.

Airborne prions can induce mad cow disease: Research

Airborne prions are also infectious and can induce mad cow disease or Creutzfeldt-Jakob disorder. This is the surprising conclusion of researchers at the University of Zurich, the University Hospital Zurich and the University of Tübingen. They recommend precautionary measures for scientific labs, slaughterhouses and animal feed plants.

Exposure to room light prior to bedtime suppresses melatonin levels, increases cancer and diabetes risk: Study

According to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism, exposure to electrical light between dusk and bedtime strongly suppresses melatonin levels and may impact physiologic processes regulated by melatonin signaling, such as sleepiness, thermoregulation, blood pressure and glucose homeostasis.

Interventions for preventing falls in older persons should include an exercise component

In the first update of the American Geriatrics Society and the British Geriatric Society's guidelines on preventing falls in older persons since 2001, they now recommend that all interventions for preventing falls should include an exercise component and that a number of new assessments should be used, including; feet and footwear, fear of falling, and ability to carry out daily living activities.

Brain cell destroying genetic mechanism responsible for development of AD

Researchers at the University of British Columbia and Vancouver Coastal Health Research Institute have discovered that the genetic mechanism which destroys brain cells is responsible for early development of Alzheimer's Disease in people with Down Syndrome and for development of Alzheimer's Disease in general population - providing a potential new target for drugs that could forestall dementia in people with either condition.

7,8-Dihydroxyflavone holds potential for treatment of fear based disorders

Living a traumatic experience favours the persistence of fear associated with an aversive stimulus, known as fear conditioning and such effect, in mice, can be suppressed with a single dosis of 7,8-Dihydroxyflavone, a type of flavonoid which boosts the ability to acquire new emotional learnings.

The neuroscience of musical chills

Scientists have found that the pleasurable experience of listening to music releases dopamine, a neurotransmitter in the brain important for more tangible pleasures associated with rewards such as food, drugs and sex. The new study from The Montreal Neurological Institute and Hospital - The Neuro at McGill University also reveals that even the anticipation of pleasurable music induces dopamine release [as is the case with food, drug, and sex cues].

Emotional stress can affect motor coordination and other cerebellum-dependent cognitive functions: Study

Research conducted by Iaroslav Savtchouk, a graduate student, and S. June Liu, PhD, Associate Professor of Cell Biology and Anatomy at LSU Health Sciences Center New Orleans, has shown that a single exposure to acute stress affected information processing in the cerebellum - the area of the brain responsible for motor control and movement coordination and also involved in learning and memory formation.

UCLA imaging system could help reveal 'miscommunications' in autism, schizophrenia

Some disorders of the brain are obvious - the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.

Aβ, tau and Fyn protein interactions may lead to brain dysfunction and AD

Though the cause of Alzheimer's disease still is unknown, recent studies have implicated three proteins strongly in its onset. New research from the University of Alabama at Birmingham, the Gladstone Institutes and the Baylor College of Medicine indicates that interactions between those three proteins might lead to brain dysfunction and AD in a mouse model of the disease.
