Scientists find that in male titi monkeys, jealousy is associated with heightened activity in the cingulate cortex, an area of the brain associated with social pain in humans, and the lateral septum, associated with pair bond formation in primates. A better understanding of jealousy may provide important clues on how to approach health and welfare […]

Duplications of large segments of noncoding DNA in the human genome may have contributed to the emergence of differences between humans and nonhuman primates, according to new results. Identifying these duplications, which include regulatory sequences, and their effect on traits and behavior may help scientists explain genetic contributions to human disease.

A new study examined the relationship between the availability of nature near city dwellers' homes and their brain health. Its findings are relevant for urban planners among others.

Scientists found that addicts who began using cocaine before and after the age of 18 showed differences in sustained attention and working memory, among other brain functions. The research, made under controlled drug abstinence condition, measured cocaine's impact on more than a hundred drug users' cognition, and recommended multidisciplinary treatment for patients with an accentuated […]

MRI-based measurements of the functional connections in the brain can help predict long-term recovery in patients who suffer neurological disability after cardiac arrest, according to new research.

In a study of 588 patients who attended an outpatient headache clinic, more frequent migraines were experienced by participants with symptoms of anxiety and depression.

One of the largest and best-documented trials of children receiving early antiretroviral therapy -- the CHER clinical trial in South Africa -- finds ongoing white matter damage in HIV-positive children at the age of 7 years. The study aims to contribute to a better understanding of brain development in HIV-infected and exposed children, as well […]

Some 40 years since CT scans first revealed abnormalities in the brains of schizophrenia patients, international scientists say the disorder is a systemic disruption to the brain's entire communication system. The study sets the stage for future research on the debilitating mental illness that affects more than 21 million people worldwide. It is the largest […]

A team of researchers reveals a mechanism that can explain how even relatively infrequent seizures can lead to long-lasting cognitive deficits in animal models.

We all know that a poor diet is unhealthy, but a new study finds that stress may just as harmful to our bodies as a really bad diet.

Cellular-level changes to a part of the brain's reward system induced by chronic exposure to the psychoactive component of marijuana may contribute to the drug's pleasurable and potentially addictive qualities, suggests a study in young mice.

A new study sheds light on how dopamine cells in the brain signal the passage of time.

Researchers have found that inducing a biochemical alteration in brain proteins via the dietary supplement glucosamine was able to rapidly dampen that pathological hyperexcitability in rat and mouse models. These results represent a potentially novel therapeutic target for the treatment of seizure disorders, and they show the need to better understand the physiology underlying these […]

Patients taking psilocybin to treat depression show reduced symptoms weeks after treatment following a 'reset' of their brain activity.

Research into the effects of brain stimulation on athletes' performance has demonstrated that it is an effective way to improve endurance. The findings are expected to advance understanding of the brain's role in endurance exercise, how it can alter the physical limits of performance in healthy people and add evidence to the debate on the […]
