A newborn baby's brain responds to being touched on the face, according to new research co-led by UCL. Babies use this sense of touch -- facial somatosensation -- to find and latch onto their mother's nipple, and should have this ability from birth. Premature babies often have difficulty feeding, and underdevelopment of their facial sensitivity may be one of the main causes.
The sight or smell of something delicious is often enough to get your mouth watering, but the physiological response to food perception may go well beyond your salivary glands. New research in mice shows that the sight and smell of food alone may be enough to kickstart processes in the liver that promote the digestion of food. The study appears Nov. 15 in the journal Cell.
The researchers explored the efficacy of a multi-therapy approach based on the disease risk factor status specific to individuals with Alzheimer's disease (AD) diagnosis or concern. The findings indicate previously unidentified connectivity between AD risk factors, suggesting that treatment regimens should be tailored to the individual and multi-modal to simultaneously return several risk factors to a normative state.
Neuronal development is often regulated by the graded distribution of guidance molecules, but many details about the process is largely unexplored. A research team from City University of Hong Kong (CityU) has tackled this problem in a precise and systematic way by developing a novel device, and has published their findings in the latest issue of Nature Communications.
For years, green has been the most reliable hue for live brain imaging, but after using a new high-throughput screening method, researchers at the John B. Pierce Laboratory and the Yale School of Medicine, together with collaborators at Stanford University, have identified a new fluorescent protein that will make it possible for live neurons to glow red when activated.
Scientists at the Virginia Tech Carilion Research Institute have solved a 125-year-old mystery of the brain, and, in the process, uncovered a potential treatment for acquired epilepsy. Perineuronal nets modulate electrical impulses in the brain, and, should the nets dissolve, brain seizures can occur.
As the adage goes 'neurons that fire together, wire together,' but a new paper published today in Neuron demonstrates that, in addition to response similarity, projection target also constrains local connectivity.
Scientists have thought that the main determinant of maximal longevity in warm-blooded animals -- which varies from as little as 2 to as many as 211 years -- is a species' metabolic rate, which is inversely related to body size. It follows that at 2 years of life, small animals with high metabolic rates are already old, but large animals with low metabolic rates are still young.
University of Tsukuba researchers revealed the importance of the brain's dopaminergic system for inhibiting already-planned actions. They trained monkeys to redirect their gaze towards targets newly presented on a screen, apart from when presented with signals to avoid such redirection. Simultaneous analysis showed that the activity of dopaminergic neurons correlated with successful refusal to redirect gaze to a new target. These findings could aid the development of treatments for diseases with impaired inhibition like Parkinson's.
New research from UC San Francisco has identified a common pattern of brain activity that may be behind low mood feelings, particularly in people who have a tendency towards anxiety. The newly discovered network is a significant advance in research on the neurobiology of mood, and could serve as a biomarker to help scientists developing new therapies to help people with mood disorders such as depression.
