      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 

      Dunn, Benjamin Adric; Battistin, Claudia (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 

      Boboeva, Vezha; Brasselet, Romain; Treves, Alessandro (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 

      Eggset, Marie (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 

      Sperlin, Josefine Rosfjord (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 

      Polti, Ignacio; Martin, Benoit; van Wassenhove, Virginie (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 

      Habli, Sarah (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 

      Carpenter, Jordan (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 ...

    • The Hippocampus Encodes Distances in Multidimensional Feature Space 

      Theves, Stephanie; Fernandez, Guillen; Doeller, Christian Fritz Andreas (Journal article; Peer reviewed, 2019)
      The hippocampal formation encodes maps of the physical environment [1, 2, 3, 4, 5]. A key question in neuroscience is whether its spatial coding principles also provide a universal metric for the organization of non-spatial ...

    • The long-term stability of new hippocampal place fields requires new protein synthesis. 

      Agnihotri, Naveen; Hawkins, Robert; Kandel, ER; Kentros, Clifford (Journal article; Peer reviewed, 2004)
      The hippocampus is critical for formation of spatial memories. Hippocampal pyramidal neurons in freely behaving animals exhibit spatially selective firing patterns, which taken together form an internal representation of ...

    • The nucleus reuniens of the thalamus sits at the nexus of a hippocampus and medial prefrontal cortex circuit enabling memory and behavior 

      Dolleman-van der Weel, Margriet J.; Griffin, Amy L.; Ito, Hiroshi; Shapiro, Matthew L.; Witter, Menno; Vertes, Robert P.; Allen, Timothy A. (Journal article; Peer reviewed, 2019)
      The nucleus reuniens of the thalamus (RE) is a key component of an extensive network of hippocampal and cortical structures and is a fundamental substrate for cognition. A common misconception is that RE is a simple relay ...
