Scientists discover a brain circuit that signals the direction and distance of boundaries in the environment
We perceive the world relative to our own body from a self-centered perspective. Yet our brain is able to transform this information into a world-centered, cognitive map of the environment, guiding us independent of where ...

Highly precise wiring in the cerebral cortex
Our brains house extremely complex neuronal circuits whose detailed structures are still largely unknown. This is especially true for the cerebral cortex of mammals, where, among other things, vision, thoughts or spatial ...

Researchers find the missing part of brain's 'internal compass'
If you have taken a walk and would like to return home you need to have an idea of where you are in relation to your destination. To do this, you need to know which way you are facing and also in which direction home lies. ...

New research finds that collective neural activity is shaped like the surface of a doughnut
High-level brain functions result from the orchestration of activity between many thousands of neurons in neural networks. For grid cells, these neural network conversations result in our understanding of location, our capacity ...

Neurons in rat brains responsible for monitoring speed identified
(Medical Xpress)—A team of researchers working at the Norwegian University of Science and Technology has isolated the neurons in the rat brain that are responsible for monitoring speed as rats run, walk or stop moving around. ...

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 ...

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 ...

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 ...
