Background and Objectives: Sick building syndrome (SBS) is a building-related illness in which people in the environment do not experience proper physical and mental well-being. Mental and physical changes include headache, nausea, abnormal fatigue, lack of concentration, sensation of an unpleasant odor. Thus, the aim of this study was to investigate the frequency of SBS and its related factors...
The rules by which odor receptors encode odors and allow behavior are still largely unexplored. Although large data sets of electrophysiological responses of receptors to odors have been generated, few hypotheses have been tested with behavioral assays. We use a data set on odor responses of Drosophila larval odor receptors coupled with chemotaxis behavioral assays to examine rules of odor codi...
Studies of kin recognition in birds have largely focused on parent-offspring recognition using auditory or visual discrimination. Recent studies indicate that birds use odors during social and familial interactions and possibly for mate choice, suggesting olfactory cues may mediate kin recognition as well. Here, we show that Humboldt penguins (Spheniscus humboldti), a natally philopatric specie...
The primary purpose of this study was to determine the effect of one versus two encoding trials in the classical yes/no recognition memory paradigm using olfactory stimuli. A group of 24 young adults rated 18 standard microencapsulated odorant targets for familiarity (first encoding block) or pleasantness (second encoding block). Once-encoded targets were in only one block and twice-encoded tar...
Social information can be acquired either directly or indirectly from cues inadvertently produced by individuals with similar interests and requirements ("inadvertent social information," ISI). These inadvertent cues provide "public information" that other individuals can use to guide their behavior. We show here that female mice use olfactory ISI to determine their choice of, and responses to,...
This study aimed to determine 1) whether certain background sounds can be matched with specific odors and 2) whether the background sounds can increase pleasantness for their congruent odors. In Experiment 1, congruent sounds increased odor pleasantness, but not odor intensity, significantly more than incongruent sounds. Experiment 2 demonstrated that certain background sounds can be paired wit...
