  1. 1. Human olfaction : Associations with longitudinal assessment of episodic memory, dementia, and mortality risk

    Author : Ingrid Ekström; Jonas Olofsson; Maria Larsson; Devangere Devanand; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; olfaction; odor identification; self-assessments; aging; episodic memory; ApoE; dementia; Alzheimer’s disease; vascular dementia; mortality; cohort study; population-based.; Psychology; psykologi;

    Abstract : 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. 2. Intimate relationships and olfaction : Body odors, adult attachment, and romance

    Author : Anna Blomkvist; Pehr Granqvist; Ilona Croy; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Intimate relationships; olfaction; body odor; attachment; sexual well-being; romantic relationships; infidelity; caregiving; intimacy; odors; psykologi; Psychology;

    Abstract : Odors influence several aspects of life, such as thoughts, memories, decisions, and emotions. Numerous studies have shown that human behavior can be affected by odors in different contexts. One such context is social relationships, in which body odors play a role. READ MORE

  3. 3. Lateralization of human olfaction : cognitive functions and electrophysiology

    Author : Daniel Broman; Steven Nordin; Matthias Laska; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Human olfaction; Laterality; Olfactory processes; Odor familiarity; Odor identification; OERP; Psychology; Psykologi;

    Abstract : 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

  4. 4. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Author : Jothi Kumar Yuvaraj; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    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).

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

    Author : Rickard Ignell; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
