Rats in Augmented Reality Help Show How the Brain Determines Location
Using augmented reality, researchers discover how rats recalibrate learned relationships between a landmark, speed, distance and time to create a locational 'map' in the brain.... Read More...
Navigating Our Thoughts: Fundamental Principles of Thinking
Researchers propose a new theory of human thinking, suggesting our brain's navigation system is key to thinking. This may explain why our knowledge seems to be organized in spatial fashion.... Read More...
How the Brain’s Grid System Maps Mental Spaces
An international team of researchers have been able to demonstrate, with electrophysiological evidence, the existence of grid-like activity in the human brain.... Read More...
How the Brain Experiences Time
Researchers have identified a network of cells in the entorhinal cortex that appear to play a key role into putting experience into a temporal context.... Read More...
Why Older People Might Lose Their Way
Researchers report the firing patterns of grid cells are less stable in older adults. This, they say, could be why older people have more problems with spatial navigation than younger people.... Read More...
Brain Takes Seconds to Switch Modes During Tasks
Switching between operational modes occurs dynamically according to the demands of the task at hand, a new study reports.... Read More...
Schizophrenia and Memory Deficits: Biological Origins of Core Schizophrenia Symptoms Discovered
A lack of adaptability in hippocampal place cells could be key to memory deficits in schizophrenia, researchers report. ... Read More...
New Model for the Origin of Grid Cells
A new study theorizes the development of grid cells depends upon the synaptic input from place cells.... Read More...
