Overlap - the degree two placefields overlap each other. Related to the statistical independence of the pair of placefields. Metric Type: Pairwise metric
Environment Coverage - the degree to which a set of placefields tile/span a given environment. Metric Type: Environment Map (collection of placecells) metric Larger values indicate that more of the environment has a placecell that represents it.
Specificity - the degree to which a given placefield is specific for a single or a few places, represented by few well-isolated peaks in the placemap. Metric Type: Single placecell metric A low value would indicate that the placefield is rather spatially diffuse across the environment.
Reliabilty - the degree to which a given placecell consistently responds to entering/exiting its preferred place. Metric Type: Single placecell metric A high value would indicate that the cell responds nearly every time that it enters the preferred place, and doesn't randomly respond when it's located at other non-preferred places.
Stability - the degree to which a placefield's preferred place remains consistent over time within the same environment. Metric Type: Single placecell metric A high value indicates that the field doesn't change much across time. If a placecell's preferred location center remains relatively constant across the experiment, it's said to be highly stable. If it moves gradually or sharply it is less stable depending on how often this happens and how far it moves.
Volitility - the first derivative of Stability Metric Type: Single placecell metric If a placecell's preferred location center changes sharply at some point during the experiment, it's said to have a high volitility.
