A study led by Dr. Ravi Muddashetty at InStem, Bangalore identified distinct markers to distinguish ribosomes that are specialized for producing specific sets of proteins and hinted that this specialization could be important for the development of the nervous system.
A Columbia University study finds that overnight the brain automatically preserves memories for important events and filters out the rest, revealing new insights into the processes that guide decision making and behavior.
Restoring the ability to walk following spinal cord injury (SCI) requires neurons in the brain to reestablish communication pathways with neurons in the spinal cord. Mature neurons, however, are unable to regenerate their axons to facilitate this process. Now, Temple scientists show that this limitation may be overcome by targeting liver kinase B1 (LKB1) protein. In mice with SCI, targeted LKB1 upregulation stimulated long-distance neuron regeneration, leading to gains in functional recovery.
Researchers in the National Institute of Information and Communications Technology (NICT), and Osaka University have identified a human white matter pathway associated with individual variability in human stereoacuity. By combining neuroimaging and psychophysical measurements, we found that the neural tissue density of the white matter pathway, the vertical occipital fasciculus (VOF), correlated with the individual variability in stereoacuity. This finding is important to understand the neural basis of dysfunction in stereopsis.
Nightmares and insomnia often accompany posttraumatic stress disorder and increase suicide risk.
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.
