Physiological properties of neurons in bat entorhinal cortex exhibit an inverse gradient along the dorsal–ventral axis compared to entorhinal neurons in rat
(Journal article; Peer reviewed, 2016)Medial entorhinal cortex (MEC) grid cells exhibit firing fields spread across the environment on the vertices of a regular tessellating triangular grid. In rodents, the size of the firing fields and the spacing between the ... -
Grid-cell representations in mental simulation
(Journal article; Peer reviewed, 2016)Anticipating the future is a key motif of the brain, possibly supported by mental simulation of upcoming events. Rodent single-cell recordings suggest the ability of spatially tuned cells to represent subsequent locations. ... -
Lack of sex-specific movement patterns in an alien species at its invasion front - consequences for invasion speed
(Journal article; Peer reviewed, 2016)Efficient targeting of actions to reduce the spread of invasive alien species relies on understanding the spatial, temporal, and individual variation of movement, in particular related to dispersal. Such patterns may differ ... -
Postnatal development of retrosplenial projections to the parahippocampal region of the rat
(Journal article; Peer reviewed, 2016)The rat parahippocampal region (PHR) and retrosplenial cortex (RSC) are cortical areas important for spatial cognition. In PHR, head-direction cells are present before eye-opening, earliest detected in postnatal day (P)11 ... -
Structural and functional changes in the hippocampal region of a transgenic rat model of Alzheimer's disease
(Doctoral theses at NTNU;2016:122, Doctoral thesis, 2016)Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that currently has no treatment to halt or cure the disease. Among the first symptoms are memory loss and learning difficulties, and as the disease ... -
Motile-Cilia-Mediated Flow Improves Sensitivity and Temporal Resolution of Olfactory Computations
(Journal article; Peer reviewed, 2017)Motile cilia are actively beating hair-like structures that cover the surface of multiple epithelia. The flow that ciliary beating generates is utilized for diverse functions and depends on the spatial location and biophysical ... -
Architecture and connectivity of the posterior parietal cortex of the rat
(Doctoral theses at NTNU;2017:29, Doctoral thesis, 2017) -
Path integral methods for the dynamics of stochastic and disordered systems
(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 ... -
Life on the edge: Latching dynamics in a Potts neural network
(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, ... -
Spatial Representation in the Hippocampal Formation: A History
(Journal article; Peer reviewed, 2017)Since the first place cell was recorded and the cognitive-map theory was subsequently formulated, investigation of spatial representation in the hippocampal formation has evolved in stages. Early studies sought to verify ... -
MicroRNAs contribute to postnatal development of laminar differences and neuronal subtypes in the rat medial entorhinal cortex
(Journal article; Peer reviewed, 2017)The medial entorhinal cortex (MEC) is important in spatial navigation and memory formation and its layers have distinct neuronal subtypes, connectivity, spatial properties, and disease susceptibility. As little is known ... -
Posterior parietal cortex
(Journal article; Peer reviewed, 2017)The posterior parietal cortex, along with temporal and prefrontal cortices, is one of the three major associative regions in the cortex of the mammalian brain. It is situated between the visual cortex at the caudal pole ... -
Parahippocampal and retrosplenial connections of rat posterior parietal cortex
(Journal article; Peer reviewed, 2017)The posterior parietal cortex has been implicated in spatial functions, including navigation. The hippocampal and parahippocampal region and the retrosplenial cortex are crucially involved in navigational processes and ... -
Activation of the hypothalamic feeding centre upon visual prey detection
(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 ... -
Plasticity of hippocampal memories in humans
(Journal article; Peer reviewed, 2017)The human hippocampus is a brain region that supports episodic and spatial memory. Recent experiments have drawn on animal research and computational modelling to reveal how the unique computations and representations of ... -
Parvalbumin and Somatostatin Interneurons Control Different Space-Coding Networks in the Medial Entorhinal Cortex
(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 ... -
Regulation of neurogenesis in the dentate gyrus and its role in anxiety-related behaviour in mice
(Doctoral theses at NTNU;2017:265, Doctoral thesis, 2017) -
Entorhinal cell-specific changes as an initial cause of Alzheimer's disease
(Doctoral theses at NTNU;2017:74, Doctoral thesis, 2017)Evidence shows that Alzheimer’s disease (AD) begins with subtle and anatomically restricted pathological changes within the brain, ultimately leading to widespread neuronal loss and dementia. While high numbers of ... -
Updating of visual orientation in a gravity-based reference frame
(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
(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 ...
