  • Minimum Description Length Codes Are Critical 

    Cubero, Ryan John Abat; Marsili, Matteo; Roudi, Yasser (Journal article; Peer reviewed, 2018)
    In the Minimum Description Length (MDL) principle, learning from the data is equivalent to an optimal coding problem. We show that the codes that achieve optimal compression in MDL are critical in a very precise sense. ...

    Wernle, Tanja (Doctoral theses at NTNU;2018:206, Doctoral thesis, 2018)
    Gittercelledynamikk i mediale entorhinal cortex Gittercelleaktivitet oppstår momentant når dyr beveger seg gjennom et miljø, og kan dermed være ansvarlig for hjernens posisjonsberegning. For å beregne avstand må ...

    With development in the synthesis of shape- and size-dependent gold (Au) nanostructures (NSs) and their applications in nanomedicine, one of the biggest challenges is to understand the interaction of these shapes with ...
  • Activation of the hypothalamic feeding centre upon visual prey detection 

    Muto, Akira; Lal, Pradeep; Ailani, Deepak; Abe, Gembu; Itoh, Mari; Kawakami, Koichi (Journal article; Peer reviewed, 2017)
    The visual system plays a major role in food/prey recognition in diurnal animals, and food intake is regulated by the hypothalamus. However, whether and how visual information about prey is conveyed to the hypothalamic ...
  • Saccades are phase-locked to alpha oscillations in the occipital and medial temporal lobe during successful memory encoding 

    Staudigl, Tobias; Hartl, Elisabeth; Noachtar, Soheyl; Doeller, Christian Fritz Andreas; Jensen, Ole (Journal article; Peer reviewed, 2017)
    Efficient sampling of visual information requires a coordination of eye movements and ongoing brain oscillations. Using intracranial and magnetoencephalography (MEG) recordings, we show that saccades are locked to the phase ...
  • TU-tagging: A method for identifying layer-enriched neuronal genes in developing mouse visual cortex 

    Tomorsky, Johanna; DeBlander, Leah; Kentros, Clifford; Doe, Chris Q; Niell, Cristopher M (Journal article; Peer reviewed, 2017)
    Thiouracil (TU)-tagging is an intersectional method for covalently labeling newly transcribed RNAs within specific cell types. Cell type specificity is generated through targeted transgenic expression of the enzyme uracil ...
  • Intrinsic Projections of Layer Vb Neurons to Layers Va, III, and II in the Lateral and Medial Entorhinal Cortex of the Rat 

    Witter, Menno; Ohara, Shinya; Onodera, Mariko; Simonsen, Øyvind Wilsgård; Yoshino, Rintaro; Hioki, Hiroyuki; Iijima, Toshio; Tsutsui, Ken-Ichiro (Journal article; Peer reviewed, 2018)
    Layer V of the entorhinal cortex (EC) receives input from the hippocampus and originates main entorhinal outputs. The deep-sublayer Vb, immunopositive for the transcription factor Ctip2, is thought to be the main recipient ...
  • 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 ...
  • Path integral methods for the dynamics of stochastic and disordered systems 

    Hertz, John A.; Roudi, Yasser; Sollich, Peter (Journal article; Peer reviewed, 2017)
    We review some of the techniques used to study the dynamics of disordered systems subject to both quenched and fast (thermal) noise. Starting from the Martin–Siggia–Rose/Janssen–De Dominicis–Peliti path integral formalism ...
  • The appropriateness of ignorance in the inverse kinetic Ising model 

    Dunn, Benjamin Adric; Battistin, Claudia (Journal article; Peer reviewed, 2017)
    We develop efficient ways to consider and correct for the effects of hidden units for the paradigmatic case of the inverse kinetic Ising model with fully asymmetric couplings. We identify two sources of error in reconstructing ...
  • A prefrontal-thalamo-hippocampal circuit for goal-directed spatial navigation 

    Ito, Hiroshi; Zhang, Sheng Jia; Witter, Menno; Moser, Edvard Ingjald; Moser, May-Britt (Journal article; Peer reviewed, 2015)
    Spatial navigation requires information about the relationship between current and future positions. The activity of hippocampal neurons appears to reflect such a relationship, representing not only instantaneous position ...
  • Life on the edge: Latching dynamics in a Potts neural network 

    Kang, Chol Jun; Naim, Michelangelo; Boboeva, Vezha; Treves, Alessandro (Journal article; Peer reviewed, 2017)
    We study latching dynamics in the adaptive Potts model network, through numerical simulations with randomly and also weakly correlated patterns, and we focus on comparing its slowly and fast adapting regimes. A measure, ...
  • Topography of Place Maps along the CA3-to-CA2 Axis of the Hippocampus 

    Lu, Li; Igarashi, Kei M; Witter, Menno; Moser, Edvard Ingjald; Moser, May-Britt (Journal article; Peer reviewed, 2015)
    We asked whether the structural heterogeneity of the hippocampal CA3-CA2 axis is reflected in how space is mapped onto place cells in CA3-CA2. Place fields were smaller and sharper in proximal CA3 than in distal CA3 and ...
  • 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 ...
  • Updating of visual orientation in a gravity-based reference frame 

    Niehof, Nynke; Tramper, Julian J; Döller, Christian Fritz Andreas; Medendorp, W Pieter (Journal article; Peer reviewed, 2017)
    The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register ...

  • Learning with unknowns: analyzing biological data in the presence of hidden variables 

    Battistin, Claudia; Dunn, Benjamin Adric; Roudi, Yasser (Journal article, 2017)
    Despite our improved ability to probe biological systems at a higher spatio-temporal resolution, the high dimensionality of the biological systems often prevents sufficient sampling of the state space. Even with large scale ...
