Lehr, Andrew; Kumar, Arvind; Tezlaff, Christian; Hafting, Torkel; Fyhn, Marianne; Stöber, Tristan Manfred (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Hippocampal region CA2 has received increased attention due to its importance in social recognition memory. While its specific function remains to be identified, there are indications that CA2 plays a major role in a variety ...

Lensjø, Kristian Kinden; Christensen, Ane Charlotte; Tennøe, Simen; Fyhn, Marianne; Hafting, Torkel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Perineuronal nets (PNNs) are specialized extracellular matrix (ECM) structures that condense around the soma and proximal dendrites of subpopulations of neurons. Emerging evidence suggests that they are involved in regulating ...

Mobarhan, Milad; Halnes, Geir; Martínez-Cañada, Pablo; Hafting, Torkel; Fyhn, Marianne; Einevoll, Gaute (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Visually evoked signals in the retina pass through the dorsal geniculate nucleus (dLGN) on the way to the visual cortex. This is however not a simple feedforward flow of information: there is a significant feedback from ...

Lepperød, Mikkel Elle; Stöber, Tristan Manfred; Hafting, Torkel; Fyhn, Marianne; Kording, Konrad Paul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)To understand the neural mechanisms underlying brain function, neuroscientists aim to quantify causal interactions between neurons, for instance by perturbing the activity of neuron A and measuring the effect on neuron B. ...

Dragly, Svenn-Arne; Mobarhan, Milad; Solbrå, Andreas Våvang; Tennøe, Simen; Hafreager, Anders; Malthe-Sørenssen, Anders; Fyhn, Marianne; Hafting, Torkel; Einevoll, Gaute (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Educational software (apps) can improve science education by providing an interactive way of learning about complicated topics that are hard to explain with text and static illustrations. However, few educational apps are ...

Buccino, Alessio Paolo; Lepperød, Mikkel Elle; Dragly, Svenn-Arne; Häfliger, Philipp; Fyhn, Marianne; Hafting, Torkel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Objective: A major goal in systems neuroscience is to determine the causal relationship between neural activity and behavior. To this end, methods that combine monitoring neural activity, behavioral tracking, and targeted ...

Lepperød, Mikkel Elle; Christensen, Ane Charlotte; Lensjø, Kristian Kinden; Buccino, Alessio Paolo; Yu, Jai; Fyhn, Marianne; Hafting, Torkel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Grid cells in the medial entorhinal cortex (MEC) exhibit remarkable spatial activity patterns with spikes coordinated by theta oscillations driven by the medial septal area (MSA). Spikes from grid cells progress relative ...

Christensen, Ane Charlotte; Lensjø, Kristian Kinden; Lepperød, Mikkel Elle; Dragly, Svenn-Arne; Sutterud, Hallvard; Blackstad, Jan Sigurd; Fyhn, Marianne; Hafting, Torkel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Grid cells are part of a widespread network which supports navigation and spatial memory. Stable grid patterns appear late in development, in concert with extracellular matrix aggregates termed perineuronal nets (PNNs) ...

Thompson, Elise Holter; Lensjø, Kristian Kinden; Wigestrand, Mattis B; Malthe-Sørenssen, Anders; Hafting, Torkel; Fyhn, Marianne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Throughout life animals learn to recognize cues that signal danger and instantaneously initiate an adequate threat response. Memories of such associations may last a lifetime and far outlast the intracellular molecules ...

Hanssen, Kine Ødegård; Grødem, Sverre; Fyhn, Marianne; Hafting, Torkel; Einevoll, Gaute; Ness, Torbjørn V; Halnes, Geir (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The perineuronal nets (PNNs) are sugar coated protein structures that encapsulate certain neurons in the brain, such as parvalbumin positive (PV) inhibitory neurons. As PNNs are theorized to act as a barrier to ion transport, ...

Støber, Tristan; Lehr, Andrew B; Hafting, Torkel; Kumar, Arvind; Fyhn, Marianne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)To make optimal use of previous experiences, important neural activity sequences must be prioritized during hippocampal replay. Integrating insights about the interplay between CA3 and CA2, we propose a conceptual framework ...

Aasebø, Ida E. J.; Lepperød, Mikkel Elle; Stavrinou, Maria; Nøkkevangen, Sandra; Einevoll, Gaute; Hafting, Torkel; Fyhn, Marianne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The activity pattern and temporal dynamics within and between neuron ensembles are essential features of information processing and believed to be profoundly affected by anesthesia. Much of our general understanding of ...
