  2. 1. Neocortical layer 2/3 microcircuits

    Author : Carl Holmgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neocortical microcircuit; layer 2 3; pyramidal cell; FSN interneuron; retrograde signaling; VGLUT3; spike-timing dependent plasticity; LTP; LTD.;

    Abstract : Pairs of interconnected neurons form elementary information processing units within neocortical microcircuits. Pyramidal cells within these microcircuits receive synaptic input, both from their connected partners, and from more distant cortical and sub-cortical regions. Consequently, they require a means to identify relevant synaptic signals. READ MORE

  4. 2. Synaptic plasticity in local networks of neocortical layer 2/3

    Author : Misha Zilberter; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neocortical microcircuit; layer 2 3; pyramidal cell; spike timing- dependent plasticity; LTP; LTD; FSN interneuron; retrograde signalling; SAT2;

    Abstract : The neocortex is a hierarchal organ in which information processing takes on place on many levels, from subcellular signalling all the way to neural networks. Neocortical local neuronal networks (microcircuits), composed of interconnected neurons, form elementary information processing units within the cortex. READ MORE

  5. 3. On the evolutionary origin of the vertebrate cortex

    Author : Shreyas M Suryanarayana; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The aim of this thesis is to dissect out the minimalistic ancestral neural hardware, which has been conserved in homologue structures of the cerebral cortex and in particular the neocortex, across vertebrates. For this purpose, we utilise the lamprey - a cyclostome (jawless vertebrate), and we compare its anatomical homologue of cortex, the lateral pallium (LPal), in terms of its connectivity, cytoarchitecture and sensory organisation with that of the mammalian neocortex.
