  2. 1. Zonal organization of the mouse olfactory systems

    Author : Fredrik Gussing; Staffan Bohm; Anna Berghard; Diego Restrepo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; olfactory; vomeronasal; gene expression; zone; organization; behavior; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Animals survey their environment for relevant odorous chemical compounds by means of the olfactory system. This system is in most vertebrates divided into a main and accessory olfactory system with two specialized neuroepithelia, the olfactory and the vomeronasal epithelium, respectively. READ MORE

  4. 2. Nerve diffusion tensor imaging

    Author : Mikael Skorpil; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that in vivo visualises random translational movement of water molecules. DTI has inherent difficulties with low signal-to-noise ratio, sensitivity to patient motion, field inhomogeneities and fast T2 relaxation. READ MORE

  5. 3. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube

    Author : Esther Maier; Lena Gunhaga; Fernando Giraldez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olfactory placode; caudal neural tube; Wnt; FGF; RA; BMP; Notch; patterning; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. READ MORE

  6. 4. Factors influencing the turnover of olfactory receptor neurons

    Author : Maja-Lena Deckner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : immunohistochemistry; in situ hybridization; rat; olfactory bulb; olfactory epithelium; axotomy; regeneration; apoptosis; BBB; VEGF; blood vessels; trophic factor; BDNF; trkB; tenascin;

    Abstract : The olfactory system has a striking capacity for neuronal plasticity throughout life and the olfactory epithelium is able to generate both neuronal and non-neuronal cells in the normal adult animal as well as after experimental injury. In contrast to primary sensory neurons, olfactory axons are able to cross the border between the PNS and CNS in the olfactory bulb after transection in the adult animal. READ MORE

  7. 5. On CNS injury and olfactory ensheathing cell engraftment strategies

    Author : I-Hui Lee; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The intrinsic regenerative capacity of the adult mammalian central nervous system (CNS) is limited because of lack of nerve-growth stimulatory factors and presence of an insurmountable molecular environment for injured axons. This thesis aims to study neural regeneration following adult CNS injury, using rodent models of spinal cord injury, dorsal root avulsion, and Parkinson s disease. READ MORE
