They have been reported in rats, [1] monkeys, [2] mice, [3] chinchillas [4] and bats, [5] but are thought to be common to all mammals, perhaps all vertebrates [6] [7] and perhaps even some invertebrates, [8] and to underlie the "sense of direction". When the animal's head is facing in the cell's "preferred firing direction" these neurons fire ...

In 1984, Ranck discovered Head-Direction cells in a neighboring structure, the post-subiculum, adding a second ingredient to the navigation system of the brain. In collaboration with Steven Fox, Ranck characterized complex-spike cells and theta cells in the hippocampal formation. [ 5 ]
They also differ from head direction cells since they don't represent a global orientation (like a compass), but the direction towards a specific object. Spatial view cells are the cells that respond in the hippocampus when a particular location is being recalled.
Neurophysiological studies of retrosplenial cortex have mainly been done in rats. Early work showed that around 8.5% of neurons in the retrosplenial cortex are head direction cells while other neurons have correlated with movement parameters such as spatial location and running speed.

A place cell is a kind of pyramidal neuron in the hippocampus that becomes active when an animal enters a particular place in its environment, which is known as the place field. Place cells are thought to act collectively as a cognitive representation of a specific location in space, known as a cognitive map. [1]
