New research sheds light on the brain's GPS system

Grid cells are the brain's GPS system. But do they use brain waves to gather information about speed and direction? Researchers at the University of Oslo resolved the question.

Mental map of space is stabilized by sugar coated neurons

A reliable sense of space is essential for daily life and memory formation. Removing sugar coated proteins around neurons in the brains' internal gps makes the mental map of space unstable, shows a study published in the ...

People with increased risk of Alzheimer's have deficits in navigating

Animals and humans have the ability to follow their own position in space through self-motion cues, even in the absence of any other sensory information. "If you get up at night and want to find your way to the bathroom in ...

Grid cells create 'treasure map' in rat brain

Grid cells and place cells are specialized neurons that allow the brain to create a map of the outside world in which one navigates (Nobel Prize 2014). This brain GPS system is built on grid cells' strikingly regular pattern ...

Paper proposes new way to understand how the neocortex works

Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual knowledge about the brain, there remains no unifying theory as to ...

Navigating our thoughts: Fundamental principles of thinking

It is one of the most fundamental questions in neuroscience: How do humans think? Until recently, we seemed far from a conclusive answer. However, scientists from the Max Planck Institute for Human Cognitive and Brain Sciences ...

Neuroscience

Oscillations provide insights into the brain's navigation system

The brain creates a map of our environment, which enables reliable spatial navigation. The Nobel Prize was awarded in 2014 for research into how this navigation system works at the cellular level. Researchers at the Medical ...

Getting lost—why older people might lose their way

Researchers at the German Center for Neurodegenerative Disease (DZNE) have found a possible explanation for the difficulty in spatial orientation sometimes experienced by elderly people. In the brains of older adults, they ...
