Deforming the metric of cognitive maps distorts memory

Entorhinal grid cells, characterized by spatially periodic activity patterns, are thought to provide a universal spatial metric. However, grid cell firing-patterns are distorted in highly polarized environments such as trapezoids. Additionally, the …

Distorting the metric of spatial memory

Entorhinal grid cells are characterized by spatially periodic patterns of activity and have been suggested to provide a metric of space. However, environmental geometry distorts grid-cell firing patterns in highly polarized trapezoidal compared to …

Temporal mapping in the human entorhinal cortex

Episodic memories are thought to be formed by binding events to their spatial as well as temporal context and medial temporal lobe structures have been implicated in the formation of such integrated memories. But which neural mechanisms allow us to …

An event map of memory space in the hippocampus

The hippocampus has long been implicated in both episodic and spatial memory, however these mnemonic functions have been traditionally investigated in separate research strands. Theoretical accounts and rodent data suggest a common mechanism for …
