  2. 1. Neural Interfaces to the Odour World of Scarab Beetles

    Author : Mattias Larsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Intra; Antennal lobe; CNS; Attraction; Olfactometer; Behaviour; Mass spectrometry; Gas chromatography; Electrophysiology; Single sensillum; Receptor neuron; Plant volatile; Sex pheromone; Neuroethology; Odour detection; Olfaction; Coleoptera; Scarabaeidae; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Abstract : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species. Electrophysiological single cell recordings in A. READ MORE

  4. 2. Biophysical chemistry of the ALS-associated protein SOD1 : Implications for folding, aggregation and in-cell behaviour

    Author : Fan Yang; Mikael Oliveberg; Per Jemth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SOD1 ALS folding in-cell NMR aggregation; Biochemistry; biokemi;

    Abstract : Biophysical chemistry deals with the structural behavior, properties and molecular function of biological macromolecules. A long-standing challenge is here to establish how these macromolecular features change upon transfer from simplified conditions in vitro to the crowded and molecularly complex environment of live cells.

  5. 3. Olfaction in Desert Locusts- Anatomy, Function and Plasticity of the Central Olfactory System

    Author : Rickard Ignell; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hist; serotonin; immunocytochemistry; juvenile hormone; development; olfactometer; intracellular recording; evolution; projection neuron; receptor neuron; antennal lobe; aggregation pheromone; neuroethology; olfaction; Desert locust; Schistocerca gregaria; Ecology; Ekologi; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Abstract : The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. READ MORE

  6. 4. Learning and memory in moths - plasticity in behaviour and neurophysiology

    Author : Ruey-Jane Fan; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proboscis extension reflex PER ; LTM; MTM; STM; memory; inter-trial-interval ITI ; inter-stimulus interval ISI ; US; CS; olfaction; Associative learning; classical conditioning; discrimination; the US pathway; Ecology; Ekologi; Animal physiology; Djurfysiologi;

    Abstract : The moth, Spodoptera littoralis, was demonstrated to be a new model system for studying mechanisms underlying odour conditioning. In the experiments a restrained moth was trained to learn an association between a conditioned stimulus (CS) and an unconditioned stimulus (US). READ MORE

  7. 5. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Author : Staffan Dryselius; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. READ MORE
