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.

Patterns of brain activity that play a role in recall of memories and decision-making

UCSF scientists have identified patterns of brain activity in the rat brain that play a role in the formation and recall of memories and decision-making. The discovery, which builds on the team's previous findings, offers a path for studying learning, decision-making and post-traumatic stress syndrome.

Awake mental replay essential for making informed choices

Awake mental replay of past experiences is essential for making informed choices, suggests a study in rats. Without it, the animals- memory-based decision-making faltered, say scientists funded by the National Institutes of Health. The researchers blocked learning from, and acting on, past experience by selectively suppressing replay - encoded as split-second bursts of neuronal activity in the memory hubs of rats performing a maze task.

Aspirin versus warfarin for heart failure patients

In a new study on more than 2,000 patients, published in the New England Journal of Medicine, researchers found that aspirin was as effective as the commonly prescribed drug warfarin. It said each drug had risks, but they had similar benefits overall.

Bionic eye helps two blind men see for the first time in 20 years

In a medical breakthrough two blind men have regained partial sight for the first time in more than 20 years after receiving a “bionic eye”. Scientists said the first clinical trials of the microchip eye implant, which measures just 3mm across and is fitted behind the eyeball, have proved successful and “exceeded expectations”.

IGF-axis proteins may have a role in development of type 2 diabetes

Researchers at Albert Einstein College of Medicine of Yeshiva University in collaboration with Nurses' Health Study investigators have shown that levels of certain related proteins found in blood are associated with a greatly reduced risk for developing type 2 diabetes up to a decade or more later. The findings, published today in the online edition of Diabetes, could open a new front in the war against diabetes.

Scientists identify first gene associated with congenital asplenia

Researchers at Weill Cornell Medical College and Rockefeller University have identified the first gene to be linked to a rare condition in which babies are born without a spleen, putting those children at risk of dying from infections they cannot defend themselves against. The gene, Nkx2.5, was shown to regulate genesis of the spleen during early development in mice.

Infants show less accurate emotion recognition for other-race faces than own-race faces

Results of a new study reported recently by psychology researcher Lisa Scott and colleagues at the University of Massachusetts Amherst confirm that although infants are born with equal abilities to tell apart people within multiple races, by age 9 months they are better at recognizing faces and emotional expressions of people within groups they interact with most.

Therapy to halt symptoms in Parkinson's patients

Parkinson's disease, a disorder which affects movement and cognition, affects over a million Americans, including actor Michael J. Fox, who first brought it to the attention of many TV-watching Americans. It's characterized by a gradual loss of neurons that produce dopamine. Mutations in the gene known as DJ-1 lead to accelerated loss of dopaminergic neurons and result in the onset of Parkinson's symptoms at a young age.

Dopamine linked to willingness to work for a monetary reward

A new brain imaging study has shown that an individual’s willingness to work hard to earn money is strongly influenced by the chemistry in three specific areas of the brain. Researchers claim that this could have important implications for the treatment of attention-deficit disorder, depression, schizophrenia and other forms of mental illness characterized by decreased motivation.

Sleep deprivation may affect surgeons' ability to tackle unexpected events

Sleep-deprived surgeons can perform a previously learned task or learn a new task as well as surgeons who are rested, according to Penn State College of Medicine researchers. However, in sleep-deprived surgeons, the brain must work harder, which could lead to problems during unexpected events.
