      Solstad, Trygve; Yousif, HN; Sejnowski, TJ (Journal article; Peer reviewed, 2014)
      Episodic-like memory is thought to be supported by attractor dynamics in the hippocampus. A possible neural substrate for this memory mechanism is rate remapping, in which the spatial map of place cells encodes contextual ...
    • Place cells in the hippocampus: Eleven maps for eleven rooms 

      Alme, Charlotte; Miao, Chenglin; Jezek, Karel; Treves, Alessandro; Moser, Edvard Ingjald; Moser, May-Britt (Journal article; Peer reviewed, 2014)
      The contribution of hippocampal circuits to high-capacity episodic memory is often attributed to the large number of orthogonal activity patterns that may be stored in these networks. Evidence for high-capacity storage in ...
    • Place cells, grid cells, and memory 

      Moser, May-Britt; Rowland, David Clayton; Moser, Edvard Ingjald (Journal article; Peer reviewed, 2015)
      The hippocampal system is critical for storage and retrieval of declarative memories, including memories for locations and events that take place at those locations. Spatial memories place high demands on capacity. Memories ...
