Border cell (brain)
Encyclopedia
Border cells are entorhinal
neurons that are border-sensitive, reacting when a border is present in the proximal environment. Cells with such firing characteristics were predicted by Neil Burgess in 2000, and detected in December 2008, according to a single report by the group of scientists that had discovered the grid cells in 2005. According to authors, border cells comprise about 10% of local population, being intermingled with grid cells and head-direction cells

Entorhinal cortex
The entorhinal cortex is located in the medial temporal lobe and functions as a hub in a widespread network for memory and navigation. The EC is the main interface between the hippocampus and neocortex...

Head direction cells
Many mammals possess neurons called head direction cells, which are active only when the animal's head points in a specific direction within an environment. These neurons fire at a steady rate Many mammals possess neurons called head direction (HD) cells, which are active only when the animal's...

Subiculum
The subiculum is the most inferior component of the hippocampal formation. It lies between the entorhinal cortex and the CA1 subfield of the hippocampus proper.-Paths:...
