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.

Norepinephrine and emotional memories

Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences.

How emotionally charged events leave their mark on memory

Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories.

Human embryonic stem cells remain embryonic because of epigenetic factors

A human embryonic stem cell is reined in - prevented from giving up its unique characteristics of self-renewal and pluripotency - by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.

Discovery offers hope of halting motor neurone disease progression

Scientists have discovered a causal link between the gene for a small protein involved in the formation of blood vessels and the development of some forms of motor neurone disease.

New findings on cholesterol metabolism in the brain and Alzheimer's disease

Although the causes of Alzheimer's disease are not completely understood, amyloid-beta (A-beta) is widely considered a likely culprit - the "sticky" protein clumps into plaques thought to harm brain cells.

Linking two molecular pieces may offer new approaches to treating Alzheimer's disease

Researchers have uncovered a biological link between the protein whose mutation causes early-onset Alzheimer's disease (AD) and a gene variant linked to late-onset AD.

PAZAR - virtual bazaar of gene regulation data

An international team has opened a virtual bazaar, called PAZAR, which allows biologists to share information about gene regulation through individually managed 'boutiques' (data collections).

Brain processes identified in humans' behavioral response to threat of punishment

Researchers have identified brain structures that process the threat of punishment for violating social norms.

Brain needs perfection in synapse number

Like Goldilocks, the brain seeks proportions that are just right. The proper number of synapses or communication between nerve cells, determined early in life, is crucial to having a healthy brain that can learn and retain information.

New understanding of how brain controls blood pressure regulation

A discovery made 25 years ago about how the brain controls blood pressure regulation is only now being explored with the help of scientists from the Howard Florey Institute.

Big bucks for cooling therapy trial for children with brain injuries

An investment of $11.5 million is being made into a clinical trial to examine a therapy for children with brain injuries.

Cholesterol levels both high and low linked to premature births

A new study suggests that not only is a very low level of cholesterol a danger to pregnant women, but high cholesterol too increases the risk of premature birth.

Day surgery for brain tumours on the NHS in Britain

A new brain surgery procedure could mean in the future that people in Britain with brain tumours may be offered day surgery under local anaesthetic on the National Health Service (NHS).

Extremely sensitive future screening technology

After the plot to blow up trans-Atlantic airlines with liquid explosives was uncovered in London in August 2006, there has been pressure on the airline industry, and Homeland Security, to find new ways to not only detect liquids in baggage and on airline passengers, but also to figure out what they are.

Humans appear to have an on-board carbon dioxide sensor

PLoS ONE publishes a study showing that inhalation of carbon dioxide (CO2) triggers emotional distress and a panic response in healthy individuals. The findings of the study posit panic as an inborn survival-oriented response.
