چکیده

1 The Olfactory Research Fund has announced that it will become the SENSE OF SMELL INSTITUTE, effective January 1, 2001. In addition, the organization’s mission has been redefined to position the SENSE OF SMELL INSTITUTE as the leading global resource relating to the sense of smell and its importance to quality of life. The announcement was made at the Fund’s annual “Night of Honors” fund-raising gala on November 14, 2000 at The Pierre. The Fund’s president, Annette Green, explained the new identity and redefined mission of the group is the result of an extensive planning process that took place over the past 6 months. “We put together a Dream Team composed of members drawn from various segments of the fragrance industry and academia to review the work of the Fund. As a result, we were able to clearly identify new, innovative programs and chart a course for the future designed to help our constituents in industry and the scientific community to successfully meet the challenges of the new millennium.” The chairman of the Board, Dr. Jack Mausner, Sr. Vice President R & D, Chanel, Inc., noted that, “when the Olfactory Research Fund started out in the early 80s, very little was known about what was then labeled ‘the mysterious fifth sense.’ To a great extent, because of the work the Fund has undertaken,” he stressed, “we now have a better understanding of the sense of smell and the key role it plays in overall well being. We have also witnessed a revolution in consumer use and attitudes toward fragrance. continued on page 6 A L S O I N T H I S I S S U E

Perceptual processing strategy and exposure influence the perception of odor mixtures.

In flavor perception, both experience with the components of odor/taste mixtures and the cognitive strategy used to examine the interactions between the components influence the overall mixture perception. However, the effect of these factors on odor mixtures perception has never been studied. The present study aimed at evaluating whether 1) previous exposure to the odorants included in a mixtu...

Judgement of odor intensity is influenced by subjects' knowledge of the odor source.

Odor perception, including intensity, is affected by knowledge of odor source. For 76 subjects tested with 24 everyday odorants, ratings of intensity, pleasantness and familiarity were enhanced when subjects either could identify the odor source themselves or were provided with the name by the experimenter. Ratings were highest when subjects judged that the names provided matched their own perc...

Perceptual blending in odor mixtures depends on the nature of odorants and human olfactory expertise.

Our olfactory system is confronted with complex mixtures of odorants, often recognized as single entities due to odor blending (e.g., coffee). In contrast, we are also able to discriminate odors from complex mixtures (e.g., off-odors). Therefore, the olfactory system is able to engage either configural or elemental processes when confronted with mixtures. However, the rules that govern the invo...

Brain responses to odor mixtures with sub-threshold components

Although most odorants we encounter in daily life are mixtures of several chemical substances, we still lack significant information on how we perceive and how the brain processes mixtures of odorants. We aimed to investigate the processing of odor mixtures using behavioral measures and functional magnetic resonance imaging (fMRI). The odor mixture contained a target odor (ambroxan) in a concen...

Newborn Rabbit Perception of 6-Odorant Mixtures Depends on Configural Processing and Number of Familiar Elements

Perception of odors, i.e. usually of mixtures of odorants, is elemental (the odorants' odor qualities are perceived in the mixture) or configural (the odor quality of the mixture differs from the one of each odorant). In human adults, the Red Cordial (RC) mixture is a configurally-processed, 6-odorant mixture. It evokes a red cordial odor quality while none of the elements carries that odor. In...
