Edvard Moser

Edvard Moser is a Norwegian neuroscientist who shared the 2014 Nobel Prize in Physiology or Medicine for discovering grid cells, which help the brain represent space.

May-Britt Moser: A Norwegian neuroscientist who shared the 2014 Nobel Prize for discoveries of cells that enable spatial navigation. She was Edvard Moser’s close collaborator in the experiments that revealed grid cells.
Grid cell: A neuron that fires at multiple locations forming a roughly hexagonal grid as an animal moves through an environment. This is the cell type Edvard and May-Britt Moser discovered.
Grid-cell discovery: The 2005 identification of neurons whose firing locations form a regularly spaced grid in an environment. This landmark experiment established the finding for which Edvard Moser became known.
2014 Nobel Prize in Physiology or Medicine: The Nobel award recognizing discoveries of cells that constitute a positioning system in the brain. Edvard Moser shared this prize with May-Britt Moser and John O'Keefe.
John O'Keefe: A British-American neuroscientist who discovered place cells and shared the 2014 Nobel Prize in Physiology or Medicine. His discovery of place cells preceded and framed the Mosers’ grid-cell finding.
Medial entorhinal cortex: A cortical region that supplies spatial and contextual information to the hippocampus. The Mosers found grid cells concentrated in this region.
Moser laboratory: A neuroscience research group founded by Edvard Moser and May-Britt Moser at the Norwegian University of Science and Technology. Its experiments developed the recording methods and research program behind the discovery.
Cognitive map: An internal representation of spatial relationships that supports flexible navigation and planning. Grid cells supplied a neural mechanism for mapping positions across space.
Per Andersen: A Norwegian neuroscientist known for research on hippocampal function and synaptic plasticity. He supervised Edvard Moser’s doctoral work on hippocampal physiology.
Place cell: A hippocampal neuron that fires when an animal occupies a particular location. Place cells and grid cells provide complementary signals for representing location.
