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 ...

Mouse memory cells are about experience, not place

When it comes to memory, it's more than just "location, location, location." New research suggests that the brain doesn't store all memories in place cells, the main type of neuron in the hippocampus, a structure crucial ...

Gene linked to intellectual ability affects memory replay in mice

Researchers at the RIKEN Center for Brain Science in Japan have discovered that a gene associated with human intellectual ability is necessary for normal memory formation in mice. Published in Nature Neuroscience, the study ...

How to reprogram memory cells in the brain

Long-term memory of specific places is stored in the brain in so-called place cells. A team of neuroscientists headed by Dr. Andrea Burgalossi of the University of Tübingen's Werner Reichardt Centre for Integrative Neuroscience ...
