Study examines incidence of concussion in youth, high school, college football A slight majority of concussions happened during youth football games but most concussions at the high school and college levels occurred during practice.
Scientists reconcile three unrelated theories of schizophrenia A new study in mice links three previously unrelated hypotheses about the causes of schizophrenia, a debilitating mental disorder that affects how people think, act and perceive reality. The new findings may eventually lead to treatment strategies targeted for the underlying causes of schizophrenia.
Popular electric brain stimulation method used to boost brain power is reduced IQ scores Using a weak electric current in an attempt to boost brainpower or treat conditions has become popular among scientists and do-it-yourselfers, but a new study shows that using the most common form of electric brain stimulation had a statistically significant detrimental effect on IQ scores.
3-D models of neuronal networks reveal organizational principles of sensory cortex Researchers have reconstructed the neuronal networks that interconnect the elementary units of sensory cortex. The scientists say that this study marks a major step forward to advance the understanding of the organizational principles of the neocortex.
Researchers observe the moment when a mind is changed Researchers studying how the brain makes decisions have recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. This basic neuroscience discovery will help create neural prostheses that can withhold moving a prosthetic arm until the user is certain of their decision, thereby averting premature or inopportune movements.
