Youth spend less time in their neighborhoods if area residents have a high fear of crime, according to a new study that used smartphones to track kids' whereabouts.  Ludwig Maximilian University of Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals they receive from neurons called place cells.  During the last decade, commercial brain-training programs have risen in popularity, offering people the hope of improving their cognitive abilities through the routine performance of various "brain games" that tap cognitive functions such as memory, attention and cognitive flexibility.  The human brain is smaller than most people imagine, it can be held in one hand and weighs about 3 pounds. However, the innocuous looking gray matter is infinitely complex and barely understood. But part of the challenge to understanding, despite the number of researchers, scientists, and doctors dedicated to its study, is that there is no central hub of information, mapping, or data gathering for brain research. Soon though, the Human Brain Project (HBP) hopes to change all that.  Many universities and institutes suggested that inside microtubules of brain cells, quantum vibrational computations were orchestrated.  New research proposes a way to test whether quantum entanglement is affected by consciousness.  Using atomic-scale quantum defects in diamonds known as nitrogen-vacancy (NV) centers to detect the magnetic field generated by neural signals, scientists working in the lab of Ronald Walsworth, a faculty member in Harvard's Center for Brain Science and Physics Department, demonstrated a noninvasive technique that can image the activity of neurons.  Neuroscience and artificial intelligence experts from Rice University and Baylor College of Medicine have taken inspiration from the human brain in creating a new "deep learning" method that enables computers to learn about the visual world largely on their own, much as human babies do.  What is the relationship of consciousness to the neurological activity of the brain? Does the brain behave differently when a person is fully conscious, when they are asleep, or when they are undergoing an epileptic seizure?
