A Compressing Auto-encoder as a Developmental Model of Grid Cells
... Although the mechanisms through which these multiple spatially scaled modules emerge are still unknown, existing neural models attribute this modular behaviour to odometry such that the change of the triangular tessellating grid cell ring is in uenced by the animal's velocity and direction inputs. ...

... There may be a tendency for cells in the infragranular layers to send local axonal collaterals to the supragranular layers, and conversely; but some collaterals also occur in the same layers as the cell bodies of their origin. These collaterals generally ramify in the immediate horizontal vicinity o ...

Subventricular zone
The subventricular zone (SVZ) is a paired brain structure situated throughout the lateral walls of the lateral ventricles. It is composed of four distinct layers of variable thickness and cell density, as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian brain.
