Resting-state gamma-band power alterations in schizophrenia reveal E/I-balance abnormalities across illness-stages
(Journal article; Peer reviewed, 2018)We examined alterations in E/I-balance in schizophrenia (ScZ) through measurements of resting-state gamma-band activity in participants meeting clinical high-risk (CHR) criteria (n = 88), 21 first episode (FEP) patients ... -
Resurgent Sodium Current in Neurons of the Cerebral Cortex
(Journal article; Peer reviewed, 2021) -
Retrosplenial connectivity with the (para)hippocampal region
(Doctoral theses at NTNU;2016:244, Doctoral thesis, 2016)The hippocampal formation and parahippocampal region (HF-PHR) receives input from a variety of cortical and subcortical structures, and one of the cortical regions which are heavily interconnected with HF-PHR is the ... -
Reward-based observational learning: Importance of social information and Anterior Cingulate Cortex for attention
(Master thesis, 2021)Observasjonslæring er en naturlig egenskap som er bevart fra gnagere til primater, men det nøyaktige underliggende nevronale grunnlaget er fortsatt ukjent. Nevroutviklingsforstyrrelser som autisme blitt assosiert med et ... -
The role of hippocampal spatial representations in contextualization and generalization of fear: Fear memory contextualization
(Peer reviewed; Journal article, 2020)Using contextual information to predict aversive events is a critical ability that protects from generalizing fear responses to safe contexts. Animal models have demonstrated the importance of spatial context representations ... -
Role of NMDA receptors in adult neurogenesis and normal development of the dentate gyrus
(Journal article; Peer reviewed, 2021)The NMDA receptors are a type of glutamate receptors, which is involved in neuronal function, plasticity and development in the mammalian brain. However, how the NMDA receptors contribute to adult neurogenesis and development ... -
Saccades are phase-locked to alpha oscillations in the occipital and medial temporal lobe during successful memory encoding
(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 ... -
Selective chemical genetic inhibition of protein kinase C epsilon reduces ethanol consumption in mice
(Journal article; Peer reviewed, 2016)Reducing expression or inhibiting translocation of protein kinase C epsilon (PKCε) prolongs ethanol intoxication and decreases ethanol consumption in mice. However, we do not know if this phenotype is due to reduced PKCε ... -
Self-organized Criticality in engineered in vitro networks; A balance of excitation and inhibition
(Master thesis, 2021)The emergence of critical dynamics has been associated with the balance of excitation to inhibition (E/I). The aim of this thesis was to explore the relationship of E/I balance with emergence of critical dynamics, stability ... -
Sequence Memory in the Hippocampal–Entorhinal Region
(Peer reviewed; Journal article, 2020)Episodic memories are constructed from sequences of events. When recalling such a memory, we not only recall individual events, but we also retrieve information about how the sequence of events unfolded. Here, we focus on ... -
Sex differences in oncogenic mutational processes
(Peer reviewed; Journal article, 2020)Sex differences have been observed in multiple facets of cancer epidemiology, treatment and biology, and in most cancers outside the sex organs. Efforts to link these clinical differences to specific molecular features ... -
Single Cell Transcriptomic and Chromatin Profiles Suggest Layer Vb Is the Only Layer With Shared Excitatory Cell Types in the Medial and Lateral Entorhinal Cortex
(Peer reviewed; Journal article, 2022)All brain functionality arises from the activity in neural circuits in different anatomical regions. These regions contain different circuits comprising unique cell types. An integral part to understanding neural circuits ... -
Sleep and Pain: An EEG study of how sleep affects pain perception
(Master thesis, 2020)Bakgrunn: Eksperimentelle studier har vist at søvnmangel er assosiert med endringer i smertepersepsjon. Flere hjerneavbildningsstudier trengs for å utvikle objektive nevrofysiologiske korrelater til smerte. Hensikt: Denne ... -
Sleep strengthens integration of spatial memory systems
(Peer reviewed; Journal article, 2021)Spatial memory comprises different representational systems that are sensitive to different environmental cues, like proximal landmarks or local boundaries. Here we examined how sleep affects the formation of a spatial ... -
Social Learning of a Spatial Task by Observation Alone
(Journal article; Peer reviewed, 2022)Interactions between conspecifics are central to the acquisition of useful memories in the real world. Observational learning, i.e., learning a task by observing the success or failure of others, has been reported in many ... -
Sparse model selection in the highly under-sampled regime
(Journal article, 2016)We propose a method for recovering the structure of a sparse undirected graphical model when very few samples are available. The method decides about the presence or absence of bonds between pairs of variable by considering ... -
Spatial Coding in the Hippocampal Region

Spatial registration of serial microscopic brain images to three-dimensional reference atlases with the QuickNII tool
(Journal article; Peer reviewed, 2019)Modern high throughput brain wide profiling techniques for cells and their morphology, connectivity, and other properties, make the use of reference atlases with 3D coordinate frameworks essential. However, anatomical ... -
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 ... -
Spatial representation of a virtual environment in a deep neural network
(Master thesis, 2020)De siste tiårene har forskere gjort store framskritt i å karakterisere det nevrobiologiske fundamentet for spatial kognisjon. Særskilt har nevrobiologiske funn ikke vært begrenset til aktiv utforskning av den fysiske ...
