A bird listening to birdsong may experience some of the same emotions as a human listening to music, suggests a new study on white-throated sparrows, published in Frontiers of Evolutionary Neuroscience.
Scientists at University College Cork (UCC) have come up with an innovative strategy to deliver a therapy into the brain to treat the neurogenerative disease, Huntington’s disease (HD). The strategy, which involves using modified sugars to carry gene therapies into the brain, is being hailed as an exciting development which could be applied to many brain disorders, especially those with a genetic basis.
Researchers have used brain imaging technology to show that young people with a known genetic risk of bipolar but no clinical signs of the condition have clear and quantifiable differences in brain activity when compared to controls.
Scientists have identified a previously unknown group of nerve cells in the brain. The nerve cells regulate cardiovascular functions such as heart rhythm and blood pressure. It is hoped that the discovery, which is published in the Journal of Clinical Investigation, will be significant in the long term in the treatment of cardiovascular diseases in humans.
Scientists say they have found a way to distinguish between different types of dementia without the need for invasive tests, like a lumbar puncture.
Scientists at the University of Western Ontario have discovered that perhaps IQ is not the best measure of cognitive performance. Instead, they found that verbal language, short-term memory, and logical reasoning were the most important predictors of cognitive performance.
