TL;DR
The importance of stimulus timing and location on the perceptual integration of taste and odour was studied based on a sub-threshold methodology and 12 people showed the integration effect previously reported while 4 showed no effect.
Abstract
The importance of stimulus timing and location on the perceptual integration of taste and odour was studied based on a sub-threshold methodology. From a panel of 16 people, 12 showed the integration effect previously reported while 4 showed no effect. The experiment was repeated using retronasal and orthonasal delivery of the odour and with tastant present or absent in the mouth. Integration of taste and odour only occurred when both stimuli were present at the same time. Retro- or orthonasal presentation both produced integration providing that tastant delivery was synchronous but the threshold values for the two presentation methods were different. The relevance of these findings to flavour perception under realistic conditions is considered.

An event‐related fMRI study investigates where in the human brain these interactions between taste and odour stimuli (administered retronasally) may be realized, and provides evidence on the neural substrate for the convergence of taste and olfactory stimuli to produce flavour in humans.

A psychophysical method is used to show cross-modal summation of subthreshold concentrations of selected gustatory and olfactory stimuli, thus demonstrating that central neural integration of taste and smell inputs generates a representation of flavor perception.

It is suggested that the insula, OFC, and ACC are key components of the network underlying flavor perception and that taste-smell integration within these and other regions is dependent on 1) mode of olfactory delivery and 2) previous experience with taste/smell combinations.

The study demonstrated that the effects of odour on taste perception are not limited to sweetness enhancement and apply to sour as well as sweet tastes and is consistent with an explanation of the taste properties of odours in terms of prior flavour-taste associations.

Time-related measurements pose some challenges to psychophysics and to applied sensory testing methods including control of psychological biases which have been found in single-point scaling, this research examined enhancement of ratings when response alternatives were limited in time-intensity scaling tasks using repeated category ratings.

The taste enhancement and suppression observed for taste-odor and taste-taste mixtures are influenced by (1) instructional sets which influence subjects’ concepts of attribute categories, and (2) the perceptual similarities among the quality dimensions of the stimulus.

The hypothesis that mouth movements play a role in retronasal odor perception analogous to that played by sniffing in orthonasal perception is suggested, and some disorders of deglutition may have associated chemosensory consequences.

This work shows that a difference in airflow between the nostrils causes each nostril to be optimally sensitized to different odorants, so that each nostrils conveys a slightly different olfactory image to the brain.
