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

    Författare :Ingrid Ekström; Jonas Olofsson; Maria Larsson; Devangere Devanand; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. Olfaction and prejudice : The role of body odor disgust sensitivity and disease avoidance in understanding social attitudes

    Författare :Marta Zakrzewska; Jonas K. Olofsson; Liuzza Marco Tullio; Sandra Soares; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; olfaction; disease avoidance; prejudice; body odors; disgust sensitivity; psykologi; Psychology;

    Sammanfattning : Disease avoidance is one of the main roles of olfaction. In particular, body odors are universal elicitors of disgust, a core emotion that plays a key role in disease avoidance. The disease avoidance theoretical framework emphasizes psychological mechanisms – attitudes and behaviors – aiming to recognize and evade pathogen threats. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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).
