1. Human olfaction Associations with longitudinal assessment of episodic memory, dementia, and mortality risk
University dissertation from Stockholm : Department of Psychology, Stockholm UniversityAbstract : A declining sense of smell is a common feature in older age. Above and beyond diminished smelling capacity due to normal processes of human aging, impairments in olfactory function have also been linked to numerous ill-health related outcomes, such as cognitive dysfunctions, dementia pathology and even an increased risk of death.

2. Lateralization of human olfaction cognitive functions and electrophysiology
University dissertation from Umeå : PsykologiAbstract : In this thesis lateralization of olfactory functions was investigated by both behavioral and electrophysiological assessment, the latter with the olfactory event-related potential (OERP) technique. The olfactory sense is primarily ipsilateral in that a stimulus that is presented to one nostril is initially processed in the same hemisphere. READ MORE

3. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology
University dissertation from Lund University, Faculty of Science, Department of BiologyAbstract : 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).

4. Olfaction in Desert Locusts- Anatomy, Function and Plasticity of the Central Olfactory System
University dissertation from Feromongruppen, Sölvegatan 37, 223 62 Lund, SwedenAbstract : 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. Clinical aspects of olfaction
University dissertation from Feromongruppen, Sölvegatan 37, 223 62 Lund, SwedenAbstract : 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
