Researchers reveal an unexpected connection between the lateral hypothalamus and the hippocampus, the respective feeding and the memory centers of the brain.
The world of the dinosaurs just got a bit more bizarre with a newly discovered species of freshwater shark whose tiny teeth resemble the alien ships from the popular 1980s video game Galaga.
Early adult general cognitive ability is a stronger predictor of cognitive function and reserve later in life than other factors, such as higher education, occupational complexity or engaging in late-life intellectual activities.
While it has been standard practice for decades to whisk newborns off to a bath within the first few hours of their birth, a new Cleveland Clinic study found that waiting to bathe a healthy newborn 12 or more hours after birth increased the rate of breastfeeding exclusivity during the newborn hospital stay. The paper was published Jan. 21 in the Journal for Obstetrics, Gynecologic, and Neonatal Nursing.
Mice growing up in a basic cage maintain lifelong visual cortex plasticity if their parents were raised in an environment that promoted social interaction and physical and mental stimulation, according to a multigenerational study published in eNeuro. The research suggests life experience may be transmitted from one generation to the next through a combination of changes in gene expression and parental caretaking behavior.
A protein-secreting device implanted into the hippocampus of epileptic rats reduces seizures by 93 percent in three months, finds preclinical research published in JNeurosci. These results support ongoing development of this technology and its potential translation into a new treatment for epilepsy.
New printing technique and materials could be used to develop intelligent materials and self-adaptive infrastructures and transducers.
Researchers have identified a cellular response to repeated concussions that may contribute to seizures in mice like those observed following traumatic brain injury in humans. The study, published in JNeurosci, establishes a new animal model that could help improve our understanding of post-traumatic epilepsy.
Today's main hypothesis about the cause of autism symptoms is that neurons receive too little inhibition or too much excitation, causing hyperexcitability. This excessive spiking interferes with normal brain function. UC Berkeley neuroscientists demonstrated that while inhibition does decrease in the brains of mice models, the changed balance between excitation and inhibition doesn't affect spiking. The altered balance seems to be a compensatory mechanism that stabilizes brain activity in response to the disorder.
In the largest study of its kind, a team led by University of Pennsylvania researchers investigated the gut microbiomes of people from seven ethnically diverse populations from remote areas of Botswana and Tanzania. Their findings illuminate the relative impact of lifestyle, geography, and genetics in shaping the microbiome.
