    • How does the grid scale support accurate spatial memory and navigation? 

      Wåga, Torgeir (Master thesis, 2013)
      How does the grid scale support accurate spatial memory and navigation? This critical piece of the puzzle is currently missing from experimental work on grid cells. Previous research has demonstrated that the medial ...

      The encoding of time and its binding to events are crucial for episodic memory, but how these processes are carried out in hippocampal–entorhinal circuits is unclear. Here we show in freely foraging rats that temporal ...

      Blackstad, Jan Sigurd Beddari (Doctoral theses at NTNU;2022:129, Doctoral thesis, 2022)
      Sammendrag Hippocampusformasjonen omfatter et område i hjernen hos pattedyr som er essensielt for romlig navigasjon og episodiske minner. Overordnet inndeles området i tre subregioner: Gyrus dentatus, cornu ammonis (CA1, ...

    • Optimized Miniature Two-Photon Microscopy for Imaging Neuronal Activity in Freely Moving Mice 

      de Jong, Nienke Laura (Master thesis, 2021)
      Oppfinnelsen av nye avbildningsteknikker har alltid banet vei for påfølgende gjennombrudd i biovitenskapen og det såkalte to-foton mikroskopet er intet unntak. Teknikken muliggjør rask, kalsiumbasert avbildning av ...

    • Parvalbumin and Somatostatin Interneurons Control Different Space-Coding Networks in the Medial Entorhinal Cortex 

      Miao, Chenglin; Cao, Qichen; Moser, May-Britt; Moser, Edvard Ingjald (Journal article; Peer reviewed, 2017)
      The medial entorhinal cortex (MEC) contains several discrete classes of GABAergic interneurons, but their specific contributions to spatial pattern formation in this area remain elusive. We employed a pharmacogenetic ...

    • Path integration in place cells of developing rats 

      Bjerknes, Tale Litlere; Dagslott, Nenitha; Moser, Edvard Ingjald; Moser, May-Britt (Journal article; Peer reviewed, 2018)
      Place cells in the hippocampus and grid cells in the medial entorhinal cortex rely on self-motion information and path integration for spatially confined firing. Place cells can be observed in young rats as soon as they ...

    • 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 ...

    • Ready, steady, go! Development of spatial representations in the rat 

      Kruge, Ingvild Ulsaker (Doctoral theses at NTNU;2016:320, Doctoral thesis, 2016)
      In mice and men, the hippocampal region is the central brain network for declarative memory and dynamic representation of location. Hippocampal place cells and entorhinal grid cells use head direction, border and speed ...

    • Representation of geometric borders in the developing rat 

      Bjerknes, Tale Litlere; Moser, Edvard Ingjald; Moser, May-Britt (Journal article; Peer reviewed, 2014)
      Local space is represented by a number of functionally specific cell types, including place cells in the hippocampus and grid cells, head direction cells, and border cells in the medial entorhinal cortex (MEC). These cells ...
