6. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology
Abstract : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).

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

8. Clinical aspects of olfaction
Abstract : The most important aims of this thesis were: (1) to investigate the prevalence of olfactory dysfunction in an adult Swedish population and to relate dysfunction to factors of possible impact on olfaction, (2) to present our experience with patients seeking medical attention for olfactory disorders, (3) to describe the relationship between detection and identification tests for olfactory disorders, (4) to assess olfactory event-related potentials (OERPs) in patients with olfactory impairment and in healthy controls, thereby exploring possibilities and limitations regarding to the clinical utility of the method, and (5) to evaluate the effect on the sense of smell of radiation in patients treated for head and neck cancer. Materials and methods: In the population-based study, 1900 adult subjects were drawn from the municipal register (I). READ MORE

9. Olfactory function after total laryngectomy in Swedish patients after rehabilitation with the Nasal Airflow-Inducing Maneuver
Abstract : After a total laryngectomy the upper and lower airways are disconnected resulting in a wide range of adverse effects, e.g. deterioration of nasal functions in breathing, loss or decrease of normal sense of smell and taste, as well as loss of normal voice. READ MORE

10. Computational Modelling of Early Olfactory Processing
Abstract : Chemical sensing is believed to be the oldest sensory ability. The chemical senses, olfaction and gustation, developed to detect and analyze information in the form of air- or waterborne chemicals, to find food and mates, and to avoid danger. READ MORE
