Stimulus-specific behavioral responses of zebrafish to a large range of odors exhibit individual variability
(Peer reviewed; Journal article, 2020)Background Odor-driven behaviors such as feeding, mating, and predator avoidance are crucial for animal survival. The neural pathways processing these behaviors have been well characterized in a number of species, and ... -
Stress disrupts insight-driven mnemonic reconfiguration in the medial temporal lobe
(Peer reviewed; Journal article, 2023)Memories are not stored in isolation. Insight into the relationship of initially unrelated events may trigger a flexible reconfiguration of the mnemonic representation of these events. Such representational changes allow ... -
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 ... -
Structural and functional dynamics of healthy and perturbed neuronal networks in vitro
(Master thesis, 2019)Rapid advancement in the field of morphogenic neuroengineering has led to interesting research perspectives in the area of in vitro neural network modeling using human induced pluripotent stem cell (hiPSC) derived neural ... -
Structural connectivity-based segmentation of the human entorhinal cortex
(Peer reviewed; Journal article, 2021)The medial (MEC) and lateral entorhinal cortex (LEC), widely studied in rodents, are well defined and characterized. In humans, however, the exact locations of their homologues remain uncertain. Previous functional magnetic ... -
Studying chronic stress and resilience in individual larval zebrafish
(Master thesis, 2021)The stress response is a natural physiological reaction necessary for adapting to an ever-changing environment, but if extended for a long period it can lead to chronic stress and to negative consequences for the organism. ... -
Studying neural circuits mediating spatial avoidance learning in zebrafish
(Doctoral theses at NTNU;2021:266, Doctoral thesis, 2021) -
Studying neuronal circuits during seizure generation
(Doctoral theses at NTNU;2020:279, Doctoral thesis, 2020) -
Synaptic connectivity of principal cells in layer II of the lateral entorhinal cortex
(Doctoral theses at NTNU;2019:279, Doctoral thesis, 2019) -
Task-dependent mixed selectivity in the subiculum
(Peer reviewed; Journal article, 2021)CA1 and subiculum (SUB) connect the hippocampus to numerous output regions. Cells in both areas have place-specific firing fields, although they are more dispersed in SUB. Weak responses to head direction and running speed ... -
TAU-COUPLING BETWEEN BRAIN ACTIVITY PATTERNS AND FINGER MOVEMENTS IN ADULTS DURING AN INTERCEPTION TASK
(Master thesis, 2021)High-density electroencephalography (EEG) was used to investigate Tau coupling between brain activity patterns and finger movements while adults were intercepting a moving target. EEG data for 12 participants were recorded ... -
Temporal changes in personal activity intelligence and the risk of incident dementia and dementia related mortality: A prospective cohort study (HUNT)
(Peer reviewed; Journal article, 2022)Background The Personal Activity Intelligence (PAI) translates heart rate during daily activity into a weekly score. Obtaining a weekly PAI score ≥100 is associated with reduced risk of premature morbidity and mortality ... -
The thalamic midline nucleus reuniens: potential relevance for schizophrenia and epilepsy
(Peer reviewed; Journal article, 2020)In this review we summarize the connectivity of the nucleus reuniens of the thalamus with the hippocampal region and the prefrontal cortex. Using data from animal studies, complemented with sparse data obtained in humans, ... -
The appropriateness of ignorance in the inverse kinetic Ising model
(Journal article; Peer reviewed, 2017)We develop efficient ways to consider and correct for the effects of hidden units for the paradigmatic case of the inverse kinetic Ising model with fully asymmetric couplings. We identify two sources of error in reconstructing ... -
The capacity for correlated semantic memories in the cortex
(Journal article; Peer reviewed, 2018)A statistical analysis of semantic memory should reflect the complex, multifactorial structure of the relations among its items. Still, a dominant paradigm in the study of semantic memory has been the idea that the mental ... -
The distribution of interneurons in the medial entorhinal cortex
(Master thesis, 2023)Mediale entorhinal cortex (MEC) er en struktur i hjernen som har fått mye oppmerksomhet for projeksjonene til hippocampus og for rollen den har i spatial navigasjon. Som andre hjerneområder, består mikronettverket til MEC ... -
The dynamics of the infant cry: An Investigation of melodic shape and prospective control in newborns
(Master thesis, 2022)Studier har vist at nyfødte spedbarn kan gjenkjenne lyder de har vært eksponert for før fødsel. Denne studien hadde som formål å ytterligere undersøke aspektet ved lydgjenkjenning hos spedbarn, ved å se på hvordan barna ... -
The effect of attention and working memory on the estimation of elapsed time
(Journal article; Peer reviewed, 2018)Psychological models of time perception involve attention and memory: while attention typically regulates the flow of events, memory maintains timed events or intervals. The precise, and possibly distinct, roles of attention ... -
The Effects of Short-Term Sleep Restriction on Proactive and Reactive Cognitive Control Regions
(Master thesis, 2020)Proaktiv og reaktiv kontroll er to modus av kognitiv kontroll som fungerer på ulike tidsskalaer og aktiverer både overlappende og distinkte hjerneregioner. Ingen tidligere studier har undersøkt hvordan hjerneregioner knyttet ... -
The Egocentric Hippocampus
(Master thesis, 2021)Navigation relies on the integration of incoming sensory information with a stable schema that can be applied to map the current environment. This integration results in a dynamic map of the animal’s position based on ...
