The Metric Content of Spatial Views as Represented in the Primate Hippocampus

Coexisting memory representations of the same information may differ in the amount of structure they embody, i.e. in the metric of relationships among individual memory items. Such an amount of structure may be quantified by the metric content index. We extract the metric content of the representation of spatial views in the monkey hippocampus and parahippocampal cortical areas, and find indications of quantitative differences that might be associated with the connectivity pattern in different neural substrates.
