Quantifying the parvalbumin-positive interneurons in the rodent lateral and medial entorhinal cortex
(Master thesis, 2019)The entorhinal cortex (EC) has been implicated in many functions related to spatial navigation, memory, and the perception of time. It is the major input and output pathway to the hippocampus, and this puts an enormous ... -
Rapid encoding of task regularities in the human hippocampus guides sensorimotor timing
(Peer reviewed; Journal article, 2022)The brain encodes the statistical regularities of the environment in a task-specific yet flexible and generalizable format. Here, we seek to understand this process by bridging two parallel lines of research, one centered ... -
Re-emphasizing early Alzheimer's disease pathology starting in select entorhinal neurons, with a special focus on mitophagy
(Peer reviewed; Journal article, 2021)The entorhinal-hippocampal system contains distinct networks subserving declarative memory. This system is selectively vulnerable to changes of ageing and pathological processes. The entorhinal cortex (EC) is a pivotal ... -
Ready, steady, go! Development of spatial representations in the rat
(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 ... -
Regional changes in parvalbumin and calbindin expression in fear memory circuits of the developing mouse brain
(Master thesis, 2022)Uttrykt i nevroner og vidt distribuert i den voksne musehjernen finner vi kalsiumbindende proteiner. Gjennom utvikling bidrar kalsiumbindende proteiner som parvalbumin og calbindin til modningen av nevrale nettverk som ... -
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) -
Regulation of Neuroinflammation by Oxidative DNA Base Lesion Repair in Alzheimer’s Disease
(Master thesis, 2021) -
Remapping and realignment in the human hippocampal formation predict context-dependent spatial behavior
(Peer reviewed; Journal article, 2021)To guide spatial behavior, the brain must retrieve memories that are appropriately associated with different navigational contexts. Contextual memory might be mediated by cell ensembles in the hippocampal formation that ... -
Representation of geometric borders in the developing rat
(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 ... -
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 ...
