Brain's navigation more complex than previously thought

Neuroscientists' discovery of grid cells, popularly known as the brain's GPS, was hailed as a major discovery. But new Stanford research suggest the system is more complicated than anyone had guessed.

In Alzheimer's, excess tau protein damages brain's GPS

Columbia University Medical Center (CUMC) researchers have discovered that the spatial disorientation that leads to wandering in many Alzheimer's disease patients is caused by the accumulation of tau protein in navigational ...

Brain's internal compass also navigates during imagination

When you try to find your way in a new place, your brain creates a spatial map that represents that environment. Neuroscientists from Radboud University's Donders Institute now show that the brain's 'navigation system' is ...

fMRI study reveals brain working's during navigation

(Medical Xpress)—A team of researchers affiliated with several academic institutions in the U.S. has learned more about the way the brain works as a person both visualizes taking a trip, and then as the trip is taken. In ...

Grid cells' role in human imagination revealed

Evidence of grid cell activity has been seen in healthy volunteers asked to imagine moving through an environment in new UCL (University College London) research funded by the Medical Research Council and Wellcome Trust.

Babies have a grasp of the physics of liquids

We are born with a basic grasp of physics, just enough not to be surprised when we interact with objects. Scientists discovered this in the past two decades. What they did not know yet was that, as early as five months of ...

Grid cells: Reading the neural code for space

The cognitive map for spatial navigation is thought to rely on grid cells. Scientists at Ludwigs-Maximilians-Universitaet in Munich and Harvard University have now put forward a mathematical theory that explains key grid-cell ...

'Odometer neurons' encode distance traveled and elapsed time

Animals navigate by calculating their current position based on how long and how far they have traveled and a new study on treadmill-running rats reveals how: neurons called grid cells integrate information about time and ...
