Wearing a specifically designed compression collar around the neck may prevent or reduce the devastating effects of head collisions in sports researchers have found. Inspired by woodpeckers and bighorn sheep the neck device called a Q-Collar is designed to press gently on the jugular vein to slow blood outflow increasing the brain's blood volume. The resulting effect of the increased blood volume helps the brain fit tighter within the skull cavity reducing the energy absorbed by the brain during collisions. The analysis of neurophysiological and neuroanatomical data from the brain showed athletes in the non-collar wearing group had significant functional
