Definitions:

Perirhinal Region

A part of the brain involved in memory and recognition, located in the medial temporal lobe adjacent to the entorhinal cortex.

Grid Cells

Neurons located in the brain's entorhinal cortex that activate when an animal is at multiple locations forming a grid-like pattern, crucial for spatial navigation.

Place Cells

Hippocampal neurons maximally responsive to specific locations in the world.

Head Direction Cells

Neurons located in several brain regions that increase their firing rates when an animal's head points in a specific direction, aiding in spatial orientation and navigation.
