Learning the native pond odor as one of the mechanisms of olfactory orientation in juvenile smooth newt Lissotriton vulgaris
Olfaction is an important mechanism of orientation in amphibians toward the breeding site. It is known that anurans can memorize the odor of the...

Expanded olfactory system in ray-finned fishes capable of terrestrial exploration
BackgroundSmell abilities differ greatly among vertebrate species due to distinct sensory needs, with exceptional variability reported in the number...

In addition to cryptochrome 2, magnetic particles with olfactory co-receptor are important for magnetic orientation in termites
The volatile trail pheromone is an ephemeral chemical cue, whereas the geomagnetic field (GMF) provides a stable positional reference. However, it is...

Olfactory Organ of Anemonefishes of the Genus Amphiprion (Amphiprioninae, Pomacentridae)
Abstract —The structure of the olfactory organ is studied in five species of anemonefishes of the genus Amphiprion : A. polymnus , A. clarkii , A....

Could olfactory identification be a prognostic factor in detecting cognitive impairment risk in the elderly?
Aging contributes to the deterioration of the olfactory system in humans. Several studies indicate that the olfactory identification test alone may...

Navigation and Orientation
When moving over both short and long distances, birds that have a specific destination must be able to determine their location and the direction...

Olfactory navigation in arthropods
Using odors to find food and mates is one of the most ancient and highly conserved behaviors. Arthropods from flies to moths to crabs use broadly...

Visual learning in tethered bees modifies flight orientation and is impaired by epinastine
Visual-orientation learning of a tethered flying bee was investigated using a flight simulator and a novel protocol in which orientation preference...

The PROUST hypothesis: the embodiment of olfactory cognition
The extension of cognition beyond the brain to the body and beyond the body to the environment is an area of debate in philosophy and the cognitive...

Morphology of the Olfactory Organ in the Climbing Perch (Anabas testudineus, Anabantidae, Perciformes)
AbstractThe structure of the olfactory organ in the climbing perch ( Anabas testudineus ) has been studied by light microscopy. The anterior nostril...

The larvae of Phyllotreta striolata share the same olfactory cues for locating Brassicaceae plant with conspecific adults
The sophisticated olfactory system of insects plays crucial roles in host plant location. In comparison with comprehensive studies on the molecular...

Unraveling the neural basis of spatial orientation in arthropods
The neural basis underlying spatial orientation in arthropods, in particular insects, has received considerable interest in recent years. This...

Morphology and Ventilation of the Olfactory Organ in Scissortail Sergeant Abudefduf sexfasciatus (Pomacentridae)
AbstractThe structure of the olfactory organ in scissortail sergeant Abudefduf sexfasciatus was studied. Smaller specimens with a total length of...

Lamina-specific immunohistochemical signatures in the olfactory bulb of healthy, Alzheimer’s and Parkinson’s disease patients
Traditional neuroanatomy immunohistology studies involve low-content analyses of a few antibodies of interest, typically applied and compared across...

Mutagenesis of the odorant receptor co-receptor (Orco) reveals severe olfactory defects in the crop pest moth Helicoverpa armigera
BackgroundOdorant receptors (ORs) as odorant-gated ion channels play a crucial role in insect olfaction. They are formed by a heteromultimeric...

Permittivity tensor imaging: modular label-free imaging of 3D dry mass and 3D orientation at high resolution
The dry mass and the orientation of biomolecules can be imaged without a label by measuring their permittivity tensor (PT), which describes how...

Companion crops alter olfactory responses of the fall armyworm (Spodoptera frugiperda) and its larval endoparasitoid (Cotesia icipe)
BackgroundThe fall armyworm (FAW), Spodoptera frugiperda , is a devastating invasive pest and a threat to food security in Africa, with yield losses...
-
Stage-specific expression of an odorant receptor underlies olfactory behavioral plasticity in Spodoptera littoralis larvae
BackgroundThe detection of environmental cues and signals via the sensory system directs behavioral choices in diverse organisms. Insect larvae rely...

Atypical Structure of Olfactory Organ in Moon Wrasse Thalassoma lunare and Sixbar Wrasse T. hardwicke (Labridae)
Abstract —The macromorphology of olfactory organ was studied in moon wrasse Thalassoma lunare and sixbar wrasse T. hardwicke . There are two nostrils...
