To rate one's individual olfactory performance is difficult and in many cases differs clearly from validated objective olfactory performance measures. This study aimed to investigate the basis for this measurement drift between objective and subjective olfactory performance evaluation. In absence of an actual odor, one may imagine an olfactory stimulus to evaluate his subjective olfactory perfo...

Thomas Reid is one of the primary early expositors of the "dual-component" theory of perception, according to which conscious perception constitutively involves a non-intentional sensation accompanied by a noninferential perceptual belief. In this paper, I will explore Reid's account of olfactory perception, and of odor as a secondary quality. Reid is often taken to endorse a broadly Lockean pi...

BACKGROUND AND AIM: The sense of taste is a chemical sense which allows everyone to perceive the flavor of what is eaten or drunk. Also, the sense of olfaction is also a chemical sense contributing to the sense of taste to perceive the taste and flavor of food. In the present work, the gustatory and olfactory function in pre- and postmenopausal women and men were studied and compared to each ot...

Awareness of the link with nature is increasingly guiding consumer choice, thus changing way in which formulations and markets are approached.Many brands have understood this now favour formulas materials natural origin.However, formulating a product can be restrictive an impact on olfactory sensoriality.Some may indeed intrinsic odour that will final formulation.The integration fragrances seem...

Remarkable advances in our understanding of olfactory perception have been made in recent years, including the discovery of new mechanisms of olfactory signaling and new principles of olfactory processing. Here, we discuss the insight that has been gained into the receptors, cells, and circuits that underlie the sense of smell.

The olfactory system has generated considerable interest in recent years, mainly focused on receptor genes and early olfactory processing. In this issue of Neuron, Mori et al. focus centrally, providing evidence for slow- and fast-wave states in olfactory cortex that appear to gate the inflow of information underlying conscious smell perception.

In both vertebrates and invertebrates, olfactory perception is mediated by G-protein-coupled receptors. Recent work, in both mouse and Caenorhabditis elegans, sheds light on the role of specific G proteins in olfactory signal transduction, neuronal morphology and axon guidance.

tory tubercle by the amygdala. The olfactory tubercle is a striatal structure with a cortical-like organization which displays odor-evoked activity and may be critical for olfactory perception (Wesson and Wilson, 2011). The anatomical findings by Novejarque et al. (2011) along with those of previous groups (Usunoff et al., 2009) suggest the involvement of the olfactory tubercle (and perhaps the...

An overview of relationships between psychophysical measures of olfactory function and reproductive neuroendocrine processes is presented. Human studies are emphasized, and the influences of gender, menstrual cycle phase, pregnancy, and injected gonadal hormones upon olfactory perception are discussed in detail. Key Words-Pregnancy, olfactory threshold, odor preferences, hormones, estrous cycle...

Although it is agreed that physicochemical features of molecules determine their perceived odor, the rules governing this relationship remain unknown. A significant obstacle to such understanding is the high dimensionality of features describing both percepts and molecules. We applied a statistical method to reduce dimensionality in both odor percepts and physicochemical descriptors for a large...
