Neuronal chemo‐architecture of the entorhinal cortex: A comparative review
(Journal article; Peer reviewed, 2019)The identification of neuronal markers, that is, molecules selectively present in subsets of neurons, contributes to our understanding of brain areas and the networks within them. Specifically, recognizing the distribution ... -
Neuronal spreading and plaque induction of intracellular Aβ and its disruption of Aβ homeostasis
(Peer reviewed; Journal article, 2021)The amyloid-beta peptide (Aβ) is thought to have prion-like properties promoting its spread throughout the brain in Alzheimer's disease (AD). However, the cellular mechanism(s) of this spread remains unclear. Here, we show ... -
Neurons and networks in the entorhinal cortex: A reappraisal of the lateral and medial entorhinal subdivisions mediating parallel cortical pathways
(Journal article; Peer reviewed, 2019)In this review, we aim to reappraise the organization of intrinsic and extrinsic networks of the entorhinal cortex with a focus on the concept of parallel cortical connectivity streams. The concept of two entorhinal areas, ... -
New solution for fast axial scanning in fluorescence microscopy
(Peer reviewed; Journal article, 2020)A novel technique based on the remote-focusing concept, using a galvanometer scanner combined with a self-fabricated "step mirror" or "tilted mirror" to transform fast lateral scanning into axial scanning, was reported as ... -
Non-hexagonal neural dynamics in vowel space
(Journal article; Peer reviewed, 2020) -
Not All That Is Gold Glitters: PV-IRES-Cre Mouse Line Shows Low Efficiency of Labeling of Parvalbumin Interneurons in the Perirhinal Cortex
(Peer reviewed; Journal article, 2021)The wide diversity of cortical inhibitory neuron types populating the cortex allows the assembly of diverse microcircuits and endows these circuits with different computational properties. Thus, characterizing neuronal ... -
Novel analytical tools reveal that local synchronization of cilia coincides with tissue-scale metachronal waves in zebrafish multiciliated epithelia
(Journal article; Peer reviewed, 2023) -
Novel Epigenetic Signatures in Alzheimer’s Disease
(Master thesis, 2022)Millions of people are currently suffering from the neurodegenerative illness, Alzheimer’s disease (AD). This disease is currently untreatable and difficult to diagnose. Oxidative stress has been shown to impact AD and the ... -
Novel Model Selection Criterion for Inference of Ising Models
(Master thesis, 2021)In this thesis we evaluate the performance of the novel Model Selection criteria proposed in Bulso et al. 2019, for inference of network topologies. To this purpose, we consider networks of binary nodes whose probability ... -
Object-centered neural coding in the entorhinal cortex and hippocampus
(Doctoral theses at NTNU;2023:24, Doctoral thesis, 2022) -
Object-centered population coding in CA1 of the hippocampus
(Peer reviewed; Journal article, 2023)Objects and landmarks are crucial for guiding navigation and must be integrated into the cognitive map of space. Studies of object coding in the hippocampus have primarily focused on activity of single cells. Here, we ... -
Observations on the Hippocampal Formation: A study on the anatomy of the dentate-ammonic region in mink, sheep, and domestic pig, and spatial representations in the CA1 and subiculum of rats.
(Doctoral theses at NTNU;2022:129, Doctoral thesis, 2022)Sammendrag Hippocampusformasjonen omfatter et område i hjernen hos pattedyr som er essensielt for romlig navigasjon og episodiske minner. Overordnet inndeles området i tre subregioner: Gyrus dentatus, cornu ammonis (CA1, ... -
On the Extraction and Analysis of Graphs From Resting-State fMRI to Support a Correct and Robust Diagnostic Tool for Alzheimer's Disease
(Journal article; Peer reviewed, 2018)The diagnosis of Alzheimer's disease (AD), especially in the early stage, is still not very reliable and the development of new diagnosis tools is desirable. A diagnosis based on functional magnetic resonance imaging (fMRI) ... -
Optimized protocol for conditioned place avoidance learning in juvenile zebrafish
(Peer reviewed; Journal article, 2021)Conditioned place avoidance assays are broadly used in mammals to study different cognitive aspects of operant learning. Here, we introduce a series of experimental designs for training juvenile zebrafish in short-term and ... -
Organization of afferent sensory input onto the mouse perirhinal cortex
(Master thesis, 2022)The perirhinal cortex is a medial temporal lobe structure situated at a very interesting position in the hierarchy of the brain. It receives projections from all sensory modalities and shows strong connectivity with the ... -
Organization of multisynaptic inputs to the dorsal and ventral dentate gyrus: retrograde trans-synaptic tracing with rabies virus vector in the rat
(Journal article; Peer reviewed, 2013)Behavioral, anatomical, and gene expression studies have shown functional dissociations between the dorsal and ventral hippocampus with regard to their involvement in spatial cognition, emotion, and stress. In this study ... -
Organization of Posterior Parietal–Frontal Connections in the Rat
(Journal article; Peer reviewed, 2019)Recent investigations of the rat posterior parietal cortex (PPC) suggest that this region plays a central role in action control together with the frontal cortical areas. Posterior parietal-frontal cortical connections ... -
Organization of projections from Perirhinal and Postrhinal Cortex to the Hippocampus in the rat
(Master thesis, 2021)Abstract will be available on 2026-12-31 -
Organization of projections from the entorhinal cortex to the hippocampal formation of the Egyptian fruit bat Rousettus aegyptiacus
(Peer reviewed; Journal article, 2023)The hippocampal formation and entorhinal cortex are crucially involved in learning and memory as well as in spatial navigation. The conservation of these structures across the entire mammalian lineage demonstrates their ... -
Origin and role of the cerebrospinal fluid bidirectional flow in the central canal
(Peer reviewed; Journal article, 2020)Circulation of the cerebrospinal fluid (CSF) contributes to body axis formation and brain development. Here, we investigated the unexplained origins of the CSF flow bidirectionality in the central canal of the spinal cord ...
