  2. 1. Drosophila Sensory Neuroethology

    Author : Suzan Mansourian; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Vinegar Fly; olfactory system; hygrosensation; receptor; ancestral habitat;

    Abstract : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.

  4. 2. 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

  5. 3. 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

  6. 4. Neural correlates of diverse navigational strategies

    Author : Marcel Sayre; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; central complex; connectome; path integration; bees; ants; neuroethology; neuroscience;

    Abstract : Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. In particular, central place foragers, such as bees and ants, have become renowned for their fascinating navigational capabilities. At the heart of insect navigation lies a brain area known as the central complex (CX). READ MORE

  7. 5. Neuroethology of olfaction in Drosophila : evolution and specialization

    Author : Irene Ibba; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In insects olfaction is a primary sensory modality. As a result changes in the animal’s ecology are often paralleled by modifications in the olfactory system. Using a comparative approach between the generalist Drosophila melanogaster and its sibling specialist D. sechellia, I looked at the coding properties of the olfactory system. READ MORE
