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 ...

Using light to reprogramme the brain's GPS

Neuroscientists at UCL have used laser beams to "switch on" neurons in mice, providing new insight into the hidden workings of memory and showing how memories underpin the brain's inner GPS system.

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 ...

Memories of movement are replayed randomly during sleep

Sleep is far from an inactive time for the brain: while rats (and humans) are asleep, neurons in the hippocampus fire rapidly. After a rat has repeatedly moved from one spot to another, the same neurons that fired while the ...
