Place-related responses have been found in cells of the Japanese macaque and common marmoset, however, whether these are true place cells or spatial view cells is still debated. [60] Spatial view cells respond to locations that are visually explored by eye movement, or the "view of a space", rather than the location of the monkey's body. [ 74 ]
Schematic of phase precession in three place cells. A rat runs left-to-right and the firing of the cells (shown as colored tick marks) is spatially localized, with the three place fields (represented by the three colors) overlapping. The local field potential theta rhythm is shown at the bottom in black.

John O'Keefe FRS FMedSci (born November 18, 1939) is an American-British neuroscientist, psychologist and a professor at University College London.. O'Keefe discovered place cells in the hippocampus, and that they show a specific kind of temporal coding in the form of theta phase precession.
Spatial view cells have been shown to respond even in the dark without any visual cues as long as the test subject was facing in the proper direction. It is believed that in the absence of visual cues, spatial view cells respond from the inputs being received from head direction cells and place cells along with eye position of the primate.
The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
Red dots indicate locations at which a particular entorhinal grid cell fired. A grid cell is a type of neuron within the entorhinal cortex that fires at regular intervals as an animal navigates an open area, allowing it to understand its position in space by storing and integrating information about location, distance, and direction. [1]
Boundary cells (also known as border cells or boundary vector cells) are neurons found in the hippocampal formation that respond to the presence of an environmental boundary at a particular distance and direction from an animal. The existence of cells with these firing characteristics were first predicted on the basis of properties of place cells.
