Jacksonville, FL (December 19, 2014) - Investigators have found that young children with type 1 diabetes (T1D) have slower brain growth compared to children without diabetes. A new study, published in the December issue of Diabetes, now available ahead of print, suggests that continued exposure to hyperglycemia, or high blood sugars, may be detrimental to the developing brain. The research was supported by the National Institutes of Health (NIH).

In a previous randomized controlled trial, Stanford University researchers developed two curricula for Girl Scouts to use energy more efficiently: one on energy use at home, and the other in transportation and food. Both courses were effective for girls in the short term, and the home energy course was effective for girls in the long term and for parents in the short term.
Subsequently, the Northern California Girl Scouts began disseminating the programs via manuals and reusable materials, but that method of disseminating the programs has not lead to widespread use.
University of Chicago developmental neuroscientists have found specific brain markers that predict generosity in children. Those neural markers appear to be linked to both social and moral evaluation processes.
Scientists at A*STAR's Institute of Medical Biology (IMB) and Institute of Molecular and Cellular Biology (IMCB) have identified a genetic pathway that accounts for the extraordinary size of the human brain. The team led by Dr Bruno Reversade from A*STAR in Singapore, together with collaborators from Harvard Medical School, have identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals.
Misfiring of the brain's control system might underpin compulsions in obsessive-compulsive disorder (OCD), according to researchers at the University of Cambridge, writing in the American Journal of Psychiatry.
Before Charlotte the spider spelled the word "humble" in her web to describe Wilbur the pig, she told Templeton the rat that the word meant "not proud."
That's probably what most people say if you put them on the spot. But if you give them time to think about it deeply, like a new study just did, other themes emerge that have a lot to do with learning.
And these intellectual dimensions of humility describe the spider as well or better than the pig.
Struggling to balance on one leg for 20 seconds or longer was linked to an increased risk for small blood vessel damage in the brain and reduced cognitive function in otherwise healthy people with no clinical symptoms, according to new research in the American Heart Association's journal Stroke.
CAMBRIDGE, MA -- For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly.
Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. However, a new study from MIT neuroscientists has found that one of the latest generation of these so-called "deep neural networks" matches the primate brain.
Primates visually recognise and determine the category of an object even at a brief glance, and to date, this behaviour has been unmatched by artificial systems. A study publishing this week in PLOS Computational Biology has found that the latest artificial "deep neural network" performs as well as the primate brain at object recognition.
Whether you're cramming for an exam or just trying to remember where you put your car keys, learning and memory are critical functions that we constantly employ in daily life.
It's no secret that people are judgmental, and young children are no exception. When children witness "good" or "bad" behavior, their brains show an immediate emotional response. But, according to a study appearing in the Cell Press journal Current Biology on December 18, it takes more than that kind of automatic moral evaluation for kids to act with generosity and share their stickers.
Behind all motor, sensory and memory functions, calcium ions are in the brain, making those functions possible. Yet neuroscientists do not entirely understand how fast calcium ions reach their targets inside neurons, and how that timing changes neural signaling. Researchers at the Okinawa Institute of Science and Technology Graduate University have determined how the distance from calcium channels to calcium sensors on vesicles affects a neuron's signaling precision and efficacy.
The part of the brain that tells us the direction to travel when we navigate has been identified by UCL scientists, and the strength of its signal predicts how well people can navigate.
It has long been known that some people are better at navigating than others, but until now it has been unclear why. The latest study, funded by the Wellcome Trust and published in Current Biology, shows that the strength and reliability of 'homing signals' in the human brain vary among people and can predict navigational ability.
Here is how it worked: the birds were placed into a wire mesh cage into which a plastic tray containing three small cups was occasionally inserted. The sample cup in the middle was covered with a small card on which was pictured a color, shape or number of items. The other two cups were also covered with cards - one that matched the sample and one that did not.
After an incomplete spinal cord injury, the body can partially recover basic motor function. So-called muscle spindles and associated sensory circuits back to the spinal cord promote the establishment of novel neuronal connections after injury. This circuit-level mechanism behind the process of motor recovery was elucidated by Prof. Silvia Arber's research group at the Biozentrum, University of Basel and the Friedrich Miescher Institute for Biomedical Research.
