A year of schooling leaves students with new knowledge, and it also equates with a small but noticeable increase to students' IQ, according to a systematic meta-analysis published in Psychological Science, a journal of the Association for Psychological Science.
Glial cells surround neurons and provide support -- not unlike hospital staff and nurses supporting doctors to keep operations running smoothly. These often-overlooked cells, which include oligodendrocytes and astrocytes, are the most abundant cell types in the central nervous system. But these cells do more than support neurons. They also actively influence them, University of California, Riverside, researchers report.
It's the comparative silence between the firing spikes of neurons that tells what they are really up to, scientists report.
The Visual Perception and Cognition Laboratory research team at the Toyohashi University of Technology has uncovered a material perception mechanism with which humans discriminate between reflective and transparent materials (mirror and glass). The research team discovered that the brain adeptly utilizes motion of complex reflective and transparent images that appear on object surfaces when distinguishing between mirror and glass. These results can be applied to reproduction technology and measurement systems based on visual perception mechanisms.
Parents who restrict their children's use of new media technologies may be acting counterproductively in the long run, particularly if they invoke afterschool homework time as the reason. Their children's scholastic achievements at college lag behind the academic performance of same-age peers, a University of Zurich study shows.
Researchers at the RIKEN Center for Brain Science in Japan have discovered that a gene associated with human intellectual ability is necessary for normal memory formation in mice. Published in Nature Neuroscience, the study shows that mice with only one copy of the gene replay shorter fragments of their previous experiences during periods of rest, impairing their ability to consolidate memories.
Some human brains are nearly twice the size of others -- but how might that matter? Researcher have discovered that these differences in size are related to the brain's shape and the way it is organized. The bigger the brain, the more its additional area is accounted for by growth in thinking areas of the cortex, or outer mantle -- at the expense of relatively slower growth in lower emotional, sensory, and motor areas.
Research from Michigan State University found that a child's ability to self-regulate is a critical element in childhood language and literacy development, and that the earlier they can hone these skills, the faster language and literacy skills develop leading to better skills in the long run.
A new study co-authored by researchers at Michigan State University and Case Western Reserve University found that 'growth mindset interventions,' or programs that teach students they can improve their intelligence with effort -- and therefore improve grades and test scores -- don't work for students in most circumstances.
The research team at Toyohashi University of Technology has measured the human pupil upon gaining insight into an object. It is known that pupils dilate/narrow to adjust the amount of light entering the eye and that emotional state affects the extent of dilation/narrowing. This study indicates that dilation extent varies depending on if inspiration occurs and that dilation occurs before inspiration. The results of the present study were published in Scientific Reports on May 2.
