  2. 1. Towards Cortex Isomorphic Attractor Neural Networks

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

    Abstract : 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. READ MORE

  4. 2. An Attractor Memory Model of Neocortex

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

    Abstract : 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. READ MORE

  5. 3. Galanin in the pituitary and in human circulation : clinical and experimental studies

    Author : Eva Grenbäck; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The neuropeptide galanin has important roles in the central and peripheral nervous systems where it affects memory, seizure activity, appetite and pain transmission. Galanin is also present in the endocrine system and one of its most prominent effects is to stimulate the release of growth hormone (GH). READ MORE
