  1. 1. Energy Transduction and Sensory Signalling in Haloarchaea Structural Characterisation of the Photocycles of Bacteriorhodopsin and Sensory Rhodopsin II

    Författare :Karl Edman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic crystallography; proton pumping; Haloarchaea; structural mechanism; bacteriorhodopsin; sensory signalling; sensory rhodopsinII; retinal proteins;

    Sammanfattning : Archaeal rhodopsins belong a subfamily of heptahelical transmembrane proteins. All contain a buried retinal chromophore covalently bound to a conserved lysine residue in helix G via a protonated Schiff base. LÄS MER

  3. 2. Fishing for Females : Sensory Exploitation in the Swordtail Characin

    Författare :Mirjam Amcoff; Niclas Kolm; Michael Ryan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Mate choice; Courtship; Sensory bias; Plasticity; Corynopoma riisei; Mulitiple signalling; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Sammanfattning : Mate choice plays an important role in sexual selection and speciation. The evolution of mate choice is intriguing in cases where choosy individuals gain little except for genetic material from the mate and where the trait used as a criterion for the choice is costly to its bearer.

  4. 3. Sensory neurons : stem cells and development

    Författare :Jens Hjerling-Leffler; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Sensory neuron; stem cells; development; boundary cap; GABA; TRPV 1; TRPA 1; TRPM8; calcium imaging; Foxs 1; SSEA-1; Schwann cells;

    Sammanfattning : The sensory nervous system is the only means we have of communicating with the surrounding world. The neurons responsible for the sensation of pain, touch, the ability to know the position of our limbs and part of maintenance of body posture are located in the dorsal root ganglia (DRG). LÄS MER

  5. 4. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

    Författare :Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

    Sammanfattning : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

  7. 5. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Författare :Karin Rylander; Göteborgs universitet; []
    Nyckelord :CT afferent; thin fibre; autonomic; insula; fMRI;

    Sammanfattning : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. LÄS MER
