  1. 1. On the role of penicillin-binding protein SpoVD in endospore cortex assembly

    Författare :Ewa Bukowska-Faniband; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sporulation; cortex; Bacillus subtilis; penicillin-binding proteins; SpoVD; peptidoglycan;

    Sammanfattning : Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. LÄS MER

  3. 2. Towards Cortex Isomorphic Attractor Neural Networks

    Författare :Christopher Johansson; KTH; []
    Nyckelord :Attractor Neural Networks; Cerebral Cortex; Minicolumns; Hypercolumns; Potts Neural Networks; BCPNN; and Parallel Computers;

    Sammanfattning : In this thesis we model the mammalian cerebral cortex withattractor neural networks and study the parallelimplementations of these models. First, we review the size, structure, and scaling laws ofthe cerebral cortex of five mammals; mouse, rat, cat, macaque,and human. LÄS MER

  4. 3. An Attractor Memory Model of Neocortex

    Författare :Christopher Johansson; Anders Lansner; Stefano Fusi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attractor Neural Networks; Cerebral Cortex; Neocortex; Brain Like Computing; Hypercolumns; Minicolumns; BCPNN; Parallel Computers; Autoassociative Memory; Computer science; Datalogi;

    Sammanfattning : This thesis presents an abstract model of the mammalian neocortex. The model was constructed by taking a top-down view on the cortex, where it is assumed that cortex to a first approximation works as a system with attractor dynamics. LÄS MER

  5. 4. A Canonical Model of the Primary Visual Cortex

    Författare :Baran Curuklu; Björn Lisper; Gaute Einevoll; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Ny datormodell visar hur hjärnan behandlar informationBaran Çürüklüs forskning handlar om att förstå hur syncentret i hjärnan fungerar. Detta är viktigt för forskningen inom neurovetenskap och artificiell intelligens. LÄS MER

  7. 5. The prefrontal cortex and information processing : nitric oxide signaling studied in an animal model of schizophrenia

    Författare :Kim Fejgin; Göteborgs universitet; []
    Nyckelord :schizophrenia; nitric oxide; prepulse inhibition; phencyclidine; prefrontal cortex; cGMP; baclofen; cognition;

    Sammanfattning : The prefrontal cortex has been extensively linked to several cognitive domains that are severely compromised in schizophrenia. It has therefore become a key region for studies on the disabling cognitive dysfunction commonly observed in patients with schizophrenia. LÄS MER
