Studying How Brains Work When Bats Are On The Move
2013-04-19 11:11:44

April Flowers for redOrbit.com - Your Universe Online Two new studies, published this week in Science, examine the mechanisms of animal navigation using bat models. RATS AND BATS The first study is the result of collaboration between University of Maryland (UMD), College Park and Boston University (BU). The findings, based on brain rhythms in bats and rats, challenges a widely-used model — based solely on rodents — of how animals navigate their environment. The study...

The Sleeping Brain Behaves As If It's Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep. The research team simultaneously measured the activity of single neurons from multiple parts of the brain involved in memory formation....

In 1619, the pioneering astronomer Johannes Kepler published Harmonices Mundi in which he analyzed data on the movement of planets and asserted that the laws of nature governing the movements of planets show features of harmonic relationships in music. In so doing, Kepler provided important support for the, then controversial, model of the universe proposed by Copernicus. In the latest issue of Biological Psychiatry, researchers at the University of California in San Diego suggest that...

An unexpected discovery has led scientists to open an intriguing new window into the human brain, via the visual system. Their finding may have implications for better understanding of states such as sleep, epilepsy and anaesthesia say the research team leaders Dr Sam Solomon and Professor Paul Martin of The Vision Centre and The University of Sydney. Potentially it could open up a new pathway for manipulating brain rhythms to manage disorders such as insomnia and epilepsy, the team speculate...

Lost your keys? Your brain might be in a better state to recall where you put them at some times than at others, according to new research from UC Davis. A paper describing the work is published June 13 in the journal Proceedings of the National Academy of Sciences. "It's been assumed that the process of retrieving a memory is cued by an external stimulus," said Charan Ranganath, professor at the UC Davis Center for Neuroscience and Department of Psychology. "But we found that the levels of...

Study suggests mental activity could stave off age-related cognitive and memory decline UC Irvine neurobiologists are providing the first visual evidence that learning promotes brain health "” and, therefore, that mental stimulation could limit the debilitating effects of aging on memory and the mind. Using a novel visualization technique they devised to study memory, a research team led by Lulu Chen and Christine Gall found that everyday forms of learning animate neuron receptors that...

When we emerge from a supermarket laden down with bags and faced with a sea of vehicles, how do we remember where we've parked our car and translate the memory into the correct action to get back there? A paper in this week's PLoS Biology identifies the specific parts of the brain responsible for solving this everyday problem. The results could have implications for understanding the functional significance of a prominent brain abnormality observed in neuropsychiatric diseases such as...
