  2. 1. 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

  4. 2. Extra- and intracellular electronic conductance of signals and its significance for synaptic plasticity

    Author : Isaac Shemer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Electrical signals play a pivotal role in the normal function of most if not all organisms. Understanding the electrophysiological principles that govern electrical signaling is essential for insights into normal- and pathological processes in cell biology. READ MORE

  5. 3. Electrochemical monitoring of living cells

    Author : Christer Spegel; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PC12; redox; electrochemistry; NAD P H; Single cell; Microchip; S. cerevisiae;

    Abstract : This thesis presents the utilization of electroanalytical methods for analysis of dynamic cellular processes such as exocytosis, intracellular redox reactions and cell surface interactions. Microchips have been designed and manufactured with the purpose of monitoring dopamine exocytosis from single or a small ensemble of PC12 cells. 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. Mechanism of action of antipsychotic drugs : focus on the nucleus accumbens and the prefronta cortex : an experimental study

    Author : Monica M Marcus; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Schizophrenia; antipsychotic drug; nucleus accumbens shell; nucleus accumbens core; prefrontal cortex; dopamine; 5-11T2A receptor; alpha1 adrenoceptor; C12 adrenoceptor; glutamate; nicotine.;

    Abstract : Antipsychotic drugs have been classified as typical or atypical. To achieve an effective antipsychotic effect with typical antipsychotic drugs, e.g. haloperidol, a dopamine D2 receptor blockade of about 70% seems necessary. READ MORE
