Investigating the connectivity of the Hippocampus in a mouse model of congenital hypoplasia of the Dentate Gyrus
(Master thesis, 2021)Hippocampus (HC) har en viktig rolle i læring og minne, og subregionen dentate gyrus (DG) er antatt å være av spesiell betydelig for å løse komplekse minneoppgaver ved å filtrere ny informasjon. For å gjøre dette utøver ... -
Investigating the Role of Ctip2 in Interneuron Subpopulations in the MEC
(Master thesis, 2023)Ctip2 är en transkriptionsfaktor som är känd för att spela en viktig roll i neuronal utveckling och differentiering. Det har varit inblandat i axonal förlängning, axonal pathfinding och kortikal utveckling. Detta examensarbete ... -
Investigating the Role of LEC LII in Hippocampal CA1 Dynamics Through Chemogenetic Manipulation
(Master thesis, 2021)Det antages at hippocampus danner minder fra input formidlet fra det mediale og laterale entorhinale cortex, som typisk tilskrives henholdsvis rumlig og ikke-rumlig informationsbehandling. Anatomiske, fysiologiske og ... -
Investigation of object memory in the Retosplenial Cortex using Calcium Imaging
(Master thesis, 2022)Episodisk hukommelse omfatter vår evne til å huske personlig erfaring (Paller, 2009; Stark, 2010), og karakteriseres ofte hos dyr som 'hva', 'hvor' og 'når' av hukommelsen (Hoffman & Washburn, 2012). Objektgjenkjenning har ... -
Investigation of the topographic organization of feedback projections from perirhinal cortex to primary somatosensory and visual cortices in the mouse
(Master thesis, 2023)Perirhinal cortex er et medialt temporallappområde som anses som en del av parahippocampiske formasjonen og har vist seg å ha fremtredende sammenkobling med cortex av alle sensoriske modaliteter hos rotter og primater. ... -
Investigative anatomical mapping of the Helicoverpa armigera antennal lobe via anterograde labeling of olfactory sensory neurons from different antennal sections
(Master thesis, 2022)Det kjemosensoriske systemet regnes som det eldste systemet fra et evolusjonært perspektiv, og det er godt representert i hele dyreriket. I de fleste organismer består den kjemosensoriske sansen av to systemer – henholdsvis ... -
Involvement of the Anterior Cingulate Cortex during Task Learning in Rats
(Master thesis, 2021)Å undersøke læring er et viktig aspekt i nevrovitenskap, da det innebærer en rekke prosesser nødvendige for en arts overlevelse. Et hjerneområde som har blitt forsket på i relasjon til læring og tilhørende kognitive ... -
Klotho and GPLD-1: Predictive Biomarkers for Development of Alzheimer's Disease in Older Adults
(Master thesis, 2023)Bakgrunn: Alzheimers sykdom (AD) er en nevrodegenerativ sykdom og den vanligste formen for demens. I 2023 påvirker demens over 55 millioner mennesker globalt, og det er forventet å øke til 152 millioner innen 2050. Likevel ... -
Knowledge Across Reference Frames: Cognitive Maps and Image Spaces
(Peer reviewed; Journal article, 2020)In human and non-human animals, conceptual knowledge is partially organized according to low-dimensional geometries that rely on brain structures and computations involved in spatial representations. Recently, two separate ... -
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 ... -
Landmark-based spatial navigation across the human lifespan

Large-scale two-photon calcium imaging in freely moving mice
(Journal article; Peer reviewed, 2022)We developed a miniaturized two-photon microscope (MINI2P) for fast, high-resolution, multiplane calcium imaging of over 1,000 neurons at a time in freely moving mice. With a microscope weight below 3 g and a highly flexible ... -
Latching dynamics as a basis for short-term recall
(Peer reviewed; Journal article, 2021)We discuss simple models for the transient storage in short-term memory of cortical patterns of activity, all based on the notion that their recall exploits the natural tendency of the cortex to hop from state to state—latching ... -
Learning and representation of hierarchical concepts in hippocampus and prefrontal cortex
(Peer reviewed; Journal article, 2021)A key aspect of conceptual knowledge is that it can be flexibly applied at different levels of abstraction, implying a hierarchical organization. It is yet unclear how this hierarchical structure is acquired and represented ... -
Learning functional connectivity in the under-sampled regime
(Doctoral theses at NTNU;2020:128, Doctoral thesis, 2020)Læring funksjonell tilkobling i under-samplet regime Siden de første dagene har nevrovitenskap forsker merket at den elektriske aktiviteten til noen nevroner i hjernen korrelerer med spesifikke trekk i den ekstern verden. ... -
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 ... -
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, ... -
Linking Structural MRI to Behavior and Real-World Emotional Experiences
(Master thesis, 2023)I kjernen av menneskelig erkjennelse ligger kompleksiteten av assosiasjoner til hjerne-atferd, hvor den ene påvirker den andre gjennom livet. Selv om det er komplisert å feste egenskaper med ett enkelt område av interesse, ... -
Local projections of layer Vb-to-Va are more prominent in lateral than in medial entorhinal cortex
(Peer reviewed; Journal article, 2021)The entorhinal cortex, in particular neurons in layer V, allegedly mediate transfer of information from the hippocampus to the neocortex, underlying long-term memory. Recently, this circuit has been shown to comprise a ... -
Loss of glutamate transporter eaat2a leads to aberrant neuronal excitability, recurrent epileptic seizures, and basal hypoactivity
(Peer reviewed; Journal article, 2021)Astroglial excitatory amino acid transporter 2 (EAAT2, GLT-1, and SLC1A2) regulates the duration and extent of neuronal excitation by removing glutamate from the synaptic cleft. Hence, an impairment in EAAT2 function could ...
