RELIANCE on sat-nav technology could be wiping our brains of vital mental maps scientists have discovered.
Researchers from the Max Planck Institute for Biological Cybernetics in Germany say the brain stores information from even a casual look at a 'proper' map and can recall it later in times of emergency.
But use of satellite navigation equipment is preventing us ever laying down these memories – leaving us potentially lost if our sat nav gives out.
One of the research team said: “ If somebody doesn’t care to learn the environment, that’s fine but they shouldn’t complain if their mobile is not working and they are completely lost.
“'Look at maps before you start your trip, keep them at hand, but navigate yourself, and try to rely on your memory. It will work better than you expect.”
