Theories of associative memory suggest that successful memory storage and recall depend on a balance between two complementary processes: pattern separation (to minimize interference) and pattern completion (to retrieve a memory when presented with partial or degraded input cues). Putative attractor circuitry in the hippocampal CA3 region is thought to be(More)
Classical theories of associative memory model CA3 as a homogeneous attractor network because of its strong recurrent circuitry. However, anatomical gradients suggest a functional diversity along the CA3 transverse axis. We examined the neural population coherence along this axis, when the local and global spatial reference frames were put in conflict with(More)
Grid cells, border cells, head-directions cells, and conjunctive correlates found in the Medial Entorhinal Cortex (MEC) indicate the presence of highly specialized neural circuits that process allocentric space. New technical advancements, as described by Tang et al. (2014) in this issue, offer an integrated approach to charting the function and(More)
