Organization of projections from Perirhinal and Postrhinal Cortex to the Hippocampus in the rat
(Master thesis, 2021)The new finding of Witter group that proved the prevailing parallel model of the organization of Parahippocampal Region (PHR), which consist of the “What” and “Where” pathway, was partially incorrect (Doan, et al., 2019). ... -
Brain and behavioural timing in an interception task involving looming danger in preterm and full-term children at school-age: A high-density EEG study
(Master thesis, 2021)Through high-density electroencephalogram (EEG), the present study investigated brain responses and timing of prospective responses to a looming stimulus in preterm and full-term children at 6 years of age. A visual paradigm ... -
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 ... -
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 ... -
Magnetic resonance-based eye tracking using deep neural networks
(Journal article, 2021)Viewing behavior provides a window into many central aspects of human cognition and health, and it is an important variable of interest or confound in many functional magnetic resonance imaging (fMRI) studies. To make eye ... -
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 ... -
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 ... -
Cognitive map formation through haptic and visual exploration of tactile city-like maps
(Peer reviewed; Journal article, 2021)In this study, we compared cognitive map formation of small-scale models of city-like environments presented in visual or tactile/haptic modalities. Previous research often addresses only a limited amount of cognitive map ... -
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 ... -
High-resolution structural analysis of layer II principal neurons in the entorhinal cortex
(Master thesis, 2021)Entorhinal cortex (EC), bestående av mediale entorhinal cortex (MEC) or lateral entorhinal cortex (LEC), mottar et rikt utvalg av kortikale signaler. Her formes og kodes signalene inn i et relevant «språk» før de, gjennom ... -
Applications of advanced MRI methods in cancer and neuroimaging
(Doctoral theses at NTNU;2021:406, Doctoral thesis, 2021)Magnetic resonance imaging (MRI) is a powerful and versatile non-invasive medical imaging modality. In this thesis, advanced MRI methods in cancer and neuroimaging were investigated. More specifically, we focus on the ... -
Assessing the Efficacy of Metacognitive Therapy for Persistent Post-Concussion Symptoms
(Master thesis, 2021)Milde traumatiske hjerneskader forårsaker symptomer som hodepine, søvnforstyrrelser, kognitiv dysfunksjon, deprimert humør og irritabilitet. For de fleste pasienter forsvinner disse symptomene etter ~ 3 måneder, men for ... -
A Statistical Physics Approach to Modelling the Joint Activity of Cortical Populations
(Master thesis, 2021)In this thesis we apply likelihood maximization methods as well as mean-field approximation to construct equilibrium and non-equilibrium Ising models for neural activity in the form of calcium imaging recordings. Before ... -
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 ... -
Interpreting wide-band neural activity using convolutional neural networks
(Peer reviewed; Journal article, 2021)Rapid progress in technologies such as calcium imaging and electrophysiology has seen a dramatic increase in the size and extent of neural recordings. Even so, interpretation of this data requires considerable knowledge ... -
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 ... -
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 ... -
Characterizing input to VIP interneurons in the entorhinal cortex
(Master thesis, 2021)The entorhinal cortex (EC) is the major input and output structure between the hippocampal formation (HF) and the rest of the brain. Here, as is the case in the rest of the cortex, there are 2 main types of cortical neurons: ... -
Multiplexing viral approaches to the study of the neuronal circuits
(Peer reviewed; Journal article, 2021)Neural circuits are composed of multitudes of elaborately interconnected cell types. Understanding neural circuit function requires not only cell-specific knowledge of connectivity, but the ability to record and manipulate ... -
Past, present and future of zebrafish in epilepsy research
(Journal article; Peer reviewed, 2021)Animal models contribute greatly to our understanding of brain development and function as well as its dysfunction in neurological diseases. Epilepsy research is a very good example of how animal models can provide us with ...
