A new study suggests drivers who follow GPS directions regularly do not engage their hippocampus, highly limiting the development of an internal map and making them more dependent on navigation devices. We’ve all heard accounts of London cabbies with juicy, swollen central lobes, stemming from the requisite training and memorization of city streets and landmarks. It turns out the inverse may also be true. This may be another classic case of if you don’t use it, you lose it.

The University College London discovered the hippocampus (used for direction and memory) and the prefrontal cortex (used for decision-making) both saw elevated levels of activity whenever drivers turned down unfamiliar streets or had free-choice to follow along their route. However, those making use of navigational systems produced no additional activity in those areas whatsoever. Zero, zilch, nada.  (Read More…)
