a Top: MRI and CT imaging showing the final electrode location. Bottom: 3D reconstruction of the segmented hippocampus showing electrode location for Subject P (left) and Subject C (right). b Schematic representation of the 3D maze. c Electrophysiological parameters used to classify cells into putative pyramidal cells (n = 204) or putative interneurons (n = 127), the cluster boundaries are calculated using the k-means algorithm. d Single-cell example of a place cell. Firing rate maps for both places (left panels, 3D trajectories colored with firing rate, black lines coming off the 3D maze indicate a flat top view of the top two floors, gray lines are trajectories and red dots are spikes) and view (right panels, unwrapped walls of the maze, color indicates firing rate when view is projected at that location, on the right gray lines correspond to view trajectories and red dots to spikes). The color indicates the firing rate. e Single-cell example of a view cell (similar panel configuration as in (d)). f Single-cell example of a mixed place and view cell (similar panel configuration as in (d)).
