How the human brain processes the perception, discrimination, and recognition of odors has not been systematically explored. Cerebral activations were therefore studied with PET during five different olfactory tasks: monorhinal smelling of odorless air (AS), single odors (OS), discrimination of odor intensity (OD-i), discrimination of odor quality (OD-q),(More)
Information on long-term memory for common odors is discussed. Olfactory parameters (i.e. familiarity, recognition, identification) and their relationship to current memory theory are highlighted. Emphasis is focused on the impact of semantic memory on episodic odor recognition. In contrast to previous research suggesting that verbal/semantic factors play a(More)
Most of the available evidence on neuropsychological functioning in anxiety disorders is based on clinical samples, investigating persons affected by obsessive-compulsive disorder. Knowledge is sparse regarding cognitive functions in other types of anxiety disorders. The aim of this study was to examine whether persons diagnosed with an anxiety disorder(More)
Only a small proportion of cancer patients undergo radical radiotherapy to the head and neck, but their needs are particularly complex. Although extensive research describes the side-effects of radiotherapy to the head and neck, few studies focus on patients' subjective experiences of eating problems and the impact these have on the patients' daily life. In(More)
This study investigated demographic and cognitive correlates of cued odor identification in a population-based sample from the Betula project: 1906 healthy adults varying in age from 45 to 90 years were assessed in a number of tasks tapping various cognitive domains, including cognitive speed, semantic memory and executive functioning. The results revealed(More)
This study addressed age distributions and experiential qualities of autobiographical memories evoked by different sensory cues. Ninety-three older adults were presented with one of three cue types (word, picture, or odor) and were asked to relate any autobiographical event for the given cue. The main aims were to explore whether (1) the age distribution of(More)
Young, young-old, and old adults were examined in immediate and delayed episodic recognition of common odors. Items were presented in 3 different formats: name-only, odor-only, or odor-name. Ss made familiarity ratings for all items at study. In the delayed recognition test, Ss were asked to name the odors. Young Ss outperformed the 2 older age groups in(More)
Behavioral evidence indicates that odor evoked autobiographical memories (OEAMs) are older, more emotional, less thought of and induce stronger time traveling characteristics than autobiographical memories (AMs) evoked by other modalities. The main aim of this study was to explore the neural correlates of AMs evoked by odors as a function of retrieval cue.(More)
The purpose of this study was to acquire a deeper understanding of head and neck cancer patients' lived experiences of daily life during the trajectory of care, with a focus on eating problems. Nine patients were interviewed in an open dialogue approximately 6 to 8 weeks after completion of radiotherapy. The data analysis was carried out using(More)
This descriptive study aimed to examine the occurrence and treatment of eating problems, and their causes and consequences during the trajectory of care for patients with head and neck cancer treated with radiotherapy. The method used was a review of patient records, conducted by means of an audit instrument developed for the study. The instrument audits(More)
