A recent study at the California National Primate Research Center studied jealousy in pair-bonded titi monkeys. The study was part of a larger study examining the neurobiology of pair-bonded primate species.
University of Pittsburgh scientists are unlocking the complexities of a recently discovered cell death process that plays a key role in health and disease, and new findings link their discovery to asthma, kidney injury and brain trauma. The results, reported today in the journal Cell, are the early steps toward drug development that could transform emergency and critical care treatment.
The brain rapidly switches between operational modes in response to tasks and what is replayed can predict how well a task will be completed, according to a new UCL study in rats.
Dion Khodagholy and colleagues have observed coordination between high-frequency oscillations (or brain waves) called 'ripples' in the rat hippocampus and parts of the brain called the association cortex.
Brazilian 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 cognitive deficit.
MRI study analyzes stress-processing brain regions in older city dwellers.
Imagine Google Earth with only the street view and a far-away satellite view but not much of a map view. Brain imaging, for the most part, has been missing just that, and a lot of research on how the brain computes happens on that map-like level. New imaging tackles this special view of the brain with the highest-energy X-rays in the country that illuminate thick sections of a mouse brain.
Salk researchers find that p75 protein is vital for signaling pain in nervous system.
UAB 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 neural and brain circuit changes.
Most autism cases are in families with no previous history of the disorder. New mutations, that occur in offspring but not in their parents, might play a role. These mutations have now been found, not just in protein-coding genome areas, but also in regulatory regions. Many are in areas that influence gene activity in the brain's striatum, which coordinates motivation, planning and other aspects of cognition.
