The relative sensitivities of the olfactory receptors in the antenna and maxillary palp of the fleshfly, Neobellieria bullata, were assessed using simultaneous electroantennograms (EAGs) and electropalpograms (EPGs). In general, the antennae and maxillary palps were more sensitive to odors related to animals (blood extract and saturated carboxylic acid) than to odors that were plant-derived (ci...

Embryonic cuttlefish can first respond to a variety of sensory stimuli during early development in the egg capsule. To examine the neural basis of this ability, we investigated the emergence of sensory structures within the developing epidermis. We show that the skin facing the outer environment (not the skin lining the mantle cavity, for example) is derived from embryonic domains expressing th...

Recent progress in the experimental morphology of the development of amphibian pituitary gland is reviewed. A series of transplantation experiments were carried out using wild-type embryos of the toad as a donor and albino embryos as a recipient. Melanin granules in the wild-type cells allowed tracing of the developmental fate of the grafts as a visible cell marker. These studies have demonstra...

transmembrane domain receptors encoded by a family Sensory stimuli are detected by specialized receptors of more than a thousand genes (Buck and Axel, 1991). in sensory organs, and the signals hence generated flow Convergent lines of evidence strongly suggest that indithrough multiple and interconnectedcenters of the brain vidual olfactory sensory neurons express only 1 or few where they are an...

ISSN 1652-6880, ISBN 978-91-576-7392-3 Female mosquitoes are vectors of diseases, affecting both livestock and humans. The host-seeking and identification behaviors of mosquitoes are mediated mainly by olfactory cues. The peripheral olfactory organs of mosquitoes which ...

background and aims. the majority of complete denture wearers are old. clinical experience suggests that complete denture wearers have various disorders in their gustatory and olfactory senses due to disturbance of airways between the oral and nasal cavities caused by upper complete denture. the purpose of this study was to evaluate the effect of upper complete denture on gustatory and olfactor...

Introduction: Smell Identification Tests (SIT) are routinely utilized for the clinical evaluation of olfactory function. Since Iran consists of various ethnic subgroups, the reliability and validity of this test as a national SIT are required to be evaluated across the country.   Materials and Methods: This cross-sectio...
