Impaired path integration in mice with disrupted grid cell firing
(PHYSorg.com Medicine & Health)

One of the most complex accomplishments of our brain is spatial orientation. To accomplish this, the brain uses various cell types including place cells and grid cells. Place cells tell the brain the current position. Scientists have already been able to confirm this in experiments. Grid cells collaborate with the place cells. But their exact function has been a matter of theoretical speculation so far.
