Architecture of the entorhinal cortex A review of entorhinal anatomy in rodents with some comparative notes
Witter, Menno; Doan, Thanh Pierre; Nilssen, Eirik Stamland; Jacobsen, Bente; Ohara, Shinya (Journal article; Peer reviewed, 2017)The entorhinal cortex (EC) is the major input and output structure of the hippocampal formation, forming the nodal point in cortico-hippocampal circuits. Different division schemes including two or many more subdivisions ... -
Convergent projections from perirhinal and postrhinal cortices suggest a multisensory nature of lateral but not medial entorhinal cortex
Doan, Thanh Pierre; Donate Lagartos, Maria Jose; Nilssen, Eirik Stamland; Ohara, Shinya; Witter, Menno (Journal article; Peer reviewed, 2019)The current model of the organization of the medial temporal lobe (MTL) episodic memory system assumes that two functionally different “where” and “what” pathways enter MTL as parallel parahippocampal cortex (PHC)-medial ... -
Immunohistochemical and electrophysiological characterization of principal cells in layer II of the lateral entorhinal cortex
Fjeld, Gunhild (Master thesis, 2015)The entorhinal cortex (EC) is a part of the medial temporal lobe of the brain, and is considered to be important for learning and memory. The EC can be divided into two subdivisions; the lateral EC (LEC) and the medial EC ... -
Inhibitory Connectivity Dominates the Fan Cell Network in Layer II of Lateral Entorhinal Cortex
Nilssen, Eirik Stamland; Jacobsen, Bente; Fjeld, Gunhild; Nair, Rajeevkumar Raveendran; Blankvoort, Stefan; Kentros, Clifford; Witter, Menno (Journal article; Peer reviewed, 2018)Fan cells in layer II of the lateral entorhinal cortex (LEC) form a main component of the projection to the dentate gyrus, CA3 and CA2 of the hippocampal formation. This projection has a counterpart originating from stellate ... -
Local projections of layer Vb-to-Va are more prominent in lateral than in medial entorhinal cortex
Ohara, Shinya; Blankvoort, Stefan; Nair Raveendran, Rajeevkumar; Nigro, Maximiliano Jose; Nilssen, Eirik Stamland; Kentros, Clifford; Witter, Menno (Peer reviewed; Journal article, 2021)The entorhinal cortex, in particular neurons in layer V, allegedly mediate transfer of information from the hippocampus to the neocortex, underlying long-term memory. Recently, this circuit has been shown to comprise a ... -
Neurons and networks in the entorhinal cortex: A reappraisal of the lateral and medial entorhinal subdivisions mediating parallel cortical pathways
Nilssen, Eirik Stamland; Doan, Thanh Pierre; Nigro, Maximiliano Jose; Ohara, Shinya; Witter, Menno (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, ... -
Processing of Gustatory Information by Protocerebral Neurons in the Moth Heliothis virescens
Nilssen, Eirik Stamland (Master thesis, 2012)Insects are guided to potential host plants by visual and olfactory signals. Upon arrival they encounter various taste stimuli, ultimately deciding whether the plant is a proper food or oviposition source. The detection ... -
Synaptic connectivity of principal cells in layer II of the lateral entorhinal cortex
Nilssen, Eirik Stamland (Doctoral theses at NTNU;2019:279, Doctoral thesis, 2019)
