... shelter characterized by both discriminative olfactory and tactile stimuli. In tests, subjects readily discriminated between shelters based on the paired stimuli. However, subjects failed to recognize the shelter in tests with either of the component stimuli alone. This result is consistent...

...: Chemotactic behaviours of Caenorhabditis elegans in a population are modulated by pheromones, leading to changes in collective behaviours. Collective behaviour Olfactory Pheromone Trail Contact Individual animals interact with others in their group, leading to changes in collective...

... ). The olfactory organs of aquatic animals are constantly exposed to soluble conspecific odorants, and fishes may be predisposed to evolve pheromonal functions for released sex hormones (and other metabolites) because they should provide reliable indicators of important reproductive events and internal...

... includes using celestial cues in combination with an internal clock, geomagnetic cues such as magnetic intensity or perhaps even olfactory cues. Presently, there is not enough evidence to rule out any of these, and years of studying birds in a laboratory setting have yielded partly contradictory results...

...Bernd Grünewald SUMMARY In order to understand the neuronal processes underlying olfactory learning, biophysical properties such as ion channel activity need to be analysed within neurons of the olfactory pathway. This study analyses voltage-sensitive ionic currents of cultured antennal lobe...
