Familiar fragrances usually induce positive mood states and elicit favorable evaluation. Relaxation is also widely thought to improve mood state. Yet experimental evidence on the effect of two different stimuli, fragrance smelling and breathing relaxation, on mood state, and fragrance evaluation is lacking. This study aimed to test (1) the effect of two familiar fragrances, lavender and myrtle,...
The sense of smell, one of the five basic senses that humans have, helps us detect different types of odors. It also plays an important role in the detection of pollutants, toxic gases, or rotten and hazardous foods. Although olfaction is considered less important than the other senses, smell disorders could cause a variety of problems, including reduced taste detection due to the relationship ...

A new study which combined associative memory tests with functional magnetic resonance imaging of the brain has identified a potential neural correlate of the special association that is formed when an odor is first paired with a visual object. Odor memories in humans are likely to be processed by a separate memory system with distinctive features that make odor memories different from visual o...
The prefrontal (PFC) and orbitofrontal cortex (OFC) appear to be associated with both executive functions and olfaction. However, there is little data relating olfactory processing and executive functions in humans. The present study aimed at exploring the role of olfaction on executive functioning, making a distinction between primary and more cognitive aspects of olfaction. Three executive ta...
OBJECTIVES Results of butanol threshold tests (BTTs) have shown that birhinal olfaction tends to converge toward monorhinal olfaction of the dominant nostril. However, birhinal olfaction may also be worse than dominant-side monorhinal olfaction. The goal of our study was to investigate the effect of deviated nasal septum on birhinal olfaction in patients with lateralized olfaction and to examin...
