Correlating data from 588 patients diagnosed with frontotemporal lobe degeneration (FTLD), researchers found that subjects with professions which related highly for verbal skills had greater tissue loss on the right hand side of the brain. By contrast, those whose professions required less aptitude for verbal skills, for example flight engineers, had more tissue damage to the left hand side of the brain.
Neuroscientists have identified an area within the brain which controls impulsive behavior and have discovered the mechanisms that affect how impulsive behavior is learned. Training rats to control impulsive responses, neuroscientists discovered electrical signals between cells in the frontal lobe grew stronger when impulses were controlled. These findings could eventually help to help diagnose and treat impulse behavior problems such as addiction, obsessive compulsive disorder and ADHD.
Researchers have discovered that children exposed to high levels of manganese in drinking water perform poorly on cognitive tests. The research stated that, on average, children who drink water with more concentrated levels of manganese have an IQ score 6 points lower than children whose drinking water contained little to no manganese.
Researchers have discovered that disabling the RGS14 gene in mice can make them smarter. When the RGS14 gene was disabled within the CA2 region of the hippocampus, researchers found that mice were better able to remember objects they had explored and learn to navigate mazes better than regular mice.
Neuroscientists have reported they have found an association between physical fitness and brain development in children. The report suggests children who are physically fitter tend to have larger hippocampi and perform better in memory based tests than their less fit counterparts.
Neuralstem has released a new report detailing positive results for stem cell treatments. Initial findings show that not only do implanted human spinal cord-derived stem cells survive, but also differentiate into neurons in rats brains affected by strokes. This finding could potentially provide new therapies for treating strokes.
New research points to a DNA sequence that causes the DUX4 gene to become more active in producing proteins that are toxic to muscle cells, leading to a form of muscular dystrophy.
This research shows that the loss of connections in the corpus collosum could be partly responsible for slower response times seen in older animals and humans due to too much crosstalk and confusion between the brain hemispheres.
UCL neuroscientists have shown that a single neuron, and even a single dendrite, can respond differently to unique sequences of input.
