New Neural Subsystems Hardwire Mice's Response to Predators

Scientists at the Brown University discovered in a new study on unsuspecting lab mice that the tiny rodents may have a specialized neural system responsible for processing their initial reaction to smells that are instinctually important. In other words, the neural network may also play a ro... [ read more >> ]
