Connectivity of Interneurons in the Entorhinal Cortex
(Doctoral theses at NTNU;2019:267, Doctoral thesis, 2019) -
Connectomics of morphogenetically engineered neurons as a predictor of functional integration in the ischemic brain
(Journal article; Peer reviewed, 2019)Recent advances in cell reprogramming technologies enable the in vitro generation of theoretically unlimited numbers of cells, including cells of neural lineage and specific neuronal subtypes from human, including ... -
Context in Spatial and Episodic Memory
(Chapter, 2020) -
Convergent projections from perirhinal and postrhinal cortices suggest a multisensory nature of lateral but not medial entorhinal cortex
(Journal article; Peer reviewed, 2019)The current model of the organization of the medial temporal lobe (MTL) episodic memory system assumes that two functionally different “where” and “what” pathways enter MTL as parallel parahippocampal cortex (PHC)-medial ... -
Coordination of entorhinal-hippocampal ensemble activity during associative learning
(Journal article; Peer reviewed, 2014)Accumulating evidence points to cortical oscillations as a mechanism for mediating interactions among functionally specialized neurons in distributed brain circuits1, 2, 3, 4, 5, 6. A brain function that may use such ... -
Correlations and functional connections in a population of grid cells
(Journal article; Peer reviewed, 2015)We study the statistics of spike trains of simultaneously recorded grid cells in freely behaving rats. We evaluate pairwise correlations between these cells and, using a maximum entropy kinetic pairwise model (kinetic Ising ... -
A Deep Learning-Based Tool for Automatic Brain Extraction from Functional Magnetic Resonance Images of Rodents
(Chapter, 2021)Removing skull artifacts from functional magnetic images (fMRI) is a well understood and frequently encountered problem. Because the fMRI field has grown mostly due to human studies, many new tools were developed to handle ... -
Defensive Behaviors - Manipulations of the Habenula-Raphe System in Freely Behaving Juvenile Zebrafish
(Master thesis, 2020)I møte med fare er frykt nødvendig for å initiere «fight-or-flight»-repsonsen, og angst fungerer som en mekanisme for risikovurdering for å estimere nivået av trussel og riktig atferds-respons. Til sammen utgjør disse to ... -
Defensive Behaviors in Juvenile Zebrafish, and the Impact of Serotonergic Manipulation on Their Behavioral Phenotype
(Master thesis, 2023)Det overordnede målet med denne avhandlingen er å utforske forsvarsadferd hos juvenile sebrafisker, med særlig interesse for hvordan manipulering av det serotonergiske systemet påvirker uttrykket av disse adferdsresponsene. ... -
Deforming the metric of cognitive maps distorts memory
(Journal article, 2019)Environmental boundaries anchor cognitive maps that support memory. However, trapezoidal boundary geometry distorts the regular firing patterns of entorhinal grid cells, proposedly providing a metric for cognitive maps. ... -
Densities and numbers of calbindin andparvalbumin positive neurons across the rat and mouse brain
(Peer reviewed; Journal article, 2020)The calcium-binding proteins parvalbumin and calbindin are expressed in neuronal populations regulating brain networks involved in spatial navigation, memory processes, and social interactions. Information about the numbers ... -
Development and topographic organization of subicular projections to lateral septum in the rat brain
(Peer reviewed; Journal article, 2020)One of the main subcortical targets of hippocampal formation efferents is the lateral septum. Previous studies on the subicular projections, as a main output structure of the hippocampus, have shown a clear topographic ... -
Development and topographical organization of projections from the hippocampus and parahippocampus to the retrosplenial cortex
(Journal article; Peer reviewed, 2019)The rat hippocampal formation (HF), parahippocampal region (PHR), and retrosplenial cortex (RSC) play critical roles in spatial processing. These regions are interconnected, and functionally dependent. The neuronal networks ... -
Development of a human cerebral organoid model for brain ischemia
(Master thesis, 2019)Å forstå de fundamentale prosessene i forbindelse med sykdom i menneskehjernene i dag, er vanskelig fordi vi mangler generalisering og overførbarhet av resultater fra eksisterende in vitro- og in vivo-modeller. Fokuset for ... -
Development of an online cognitive monitoring system for detecting looming-related responses in the infant brain
(Master thesis, 2020)For vår overlevelse er det avgjørende å kunne reagere raskt på et objekt som kommer mot deg med høy hastighet, og utøver nødvendige manøvrer for å unngå en forestående kollisjon. Disse objektene refererer vi til som ... -
Development of the Entorhinal Cortex Occurs via Parallel Lamination During Neurogenesis
(Peer reviewed; Journal article, 2021)The entorhinal cortex (EC) is the spatial processing center of the brain and structurally is an interface between the three layered paleocortex and six layered neocortex, known as the periarchicortex. Limited studies ... -
Development of the neural representation of space
(Doctoral theses at NTNU;2018:170, Doctoral thesis, 2018)Hjernens navigasjonssystem består av flere typer nevroner, blant annet plassceller i hippocampus og gitterceller, hoderetningsceller og grenseceller i mediale entorhinale korteks (MEC), samt i pre- og parasubiculum. De ... -
Developmental mechanisms of spontaneous and sensory evoked activity in the zebrafish habenula
(Doctoral theses at NTNU;2020:306, Doctoral thesis, 2020)Utviklingsmekanismer for spontan- og sensorisk vekket aktivitet i habenula i sebrafisk For å kunne utføre fleksible endringer i vår atferd må vi kunne samle inn og evaluere informasjon som kommer fra både interne kilder ... -
Differences in diurnal saliva cortisol variation between patients with Chronic Fatigue Syndrome and patients with Fibromyalgia, and the role of Insomnia Severity as a predictor.
(Master thesis, 2019)Objective: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a severe chronic disease, that severely impacts the quality of life. The underlying pathophysiology of CFS/ME is still unknown, but a substantial ... -
Dissociation between postrhinal cortex and downstream parahippocampal regions in the representation of egocentric boundaries
(Journal article; Peer reviewed, 2019)Navigation requires the integration of many sensory inputs to form a multi-modal cognitive map of the environment, which is believed to be implemented in the hippocampal region by spatially tuned cells [1, 2, 3, 4, 5, 6, ...
