From high‐resolution (65 μm) data acquired by magnetic resonance imaging, we have reconstructed the nasal passageway of a single adult hagfish specimen (probably Eptatretus stoutii). We have used this reconstruction to investigate how the anatomy and morphometry of the nasal passageway influence the olfactory ability of the hagfish. We found that the long, broad section of the passageway preceding the nasal chamber will delay the response to an odor by 1–2 s. Diffusion of odorant to the… Expand

TLDR
The nasal bridge and the incurrent vortex are pivotal to olfaction in the pike, and the boundary layer could delay considerably odorant transport from the external environment to the nasal region. Expand
Motion-driven flow in an unusual piscine nasal region.
TLDR
Olfactory flow in the adult garpike Belone belone (Belonidae, Teleostei), a fish with an unusual nasal region, can be generated by its motion relative to water (swimming, or an external current, or both), and it is found that the mouth and the base of the garpik's jaws may assist the sampling process.

Olfactory flow in the sea catfish, Ariopsis felis (L.): Origin, regulation, and resampling.
TLDR
Olfactory flow in the sea catfish is regulated and thoroughly sampled by novel mechanisms, and flow through the nasal chamber is regulated by a mobile nasal flap. Expand
A Computational Study of the Hydrodynamics in the Nasal Region of a Hammerhead Shark (Sphyrna tudes): Implications for Olfaction
TLDR
The hammerhead shark appears to utilize external (major and minor nasal grooves) and internal (apical gap) flow regulation mechanisms to limit water flow between the olfactory lamellae, thus protecting these delicate structures from otherwise high flow rates incurred by sampling a larger area.

TLDR
It is concluded that swimming alone is sufficient to drive olfactory flow in H. dauricus, and the implications for the three other extant genera of sturgeons (Acipenser, Pseudoscaphirhynchus and Scaphirnchus), and for other fishes with Olfactory rosettes. Expand
Complex flow in the nasal region of guitarfishes.
TLDR
A model for olfactory flow in guitarfishes with open nasal cavities is proposed, and other neoselachians which this model might apply to are suggested. Expand
Ciliary function in the olfactory organs of sharks and rays
TLDR
Using evidence from 31 species of neoselachian, this review attempts to identify the fluid - water or mucus - propelled by these cilia, and suggests that the cilia propel mucus. Expand
Functional nasal morphology of chimaerid fishes
TLDR
The nasal region of chimaerid fishes shows at least two adaptations to a benthic lifestyle, and suggests good olfactory sensitivity, with secondary folding enhancing the hypothetical flat sensory surface area by up to 70%. Expand

The Korean shuttles mudskipper Periophthalmus modestus has paired olfactory organs on its snout, consisting of anterior and posterior nostrils, a single olfactory canal with sensory and nonsensoryExpand
Motile-Cilia-Mediated Flow Improves Sensitivity and Temporal Resolution of Olfactory Computations
TLDR
This work unravels a central function of ciliary beating for generating flow fields that increase the sensitivity and the temporal resolution of olfactory computations in the vertebrate brain. Expand

The fluid dynamics of canine olfaction: unique nasal airflow patterns as an explanation of macrosmia
TLDR
It is proposed that mammalian Olfactory function and acuity may largely depend on odorant transport by nasal airflow patterns resulting from either the presence of a highly developed olfactory recess or the lack of one, in macrosmats such as the canine or in microsmats including humans. Expand
Reconstruction and morphometric analysis of the nasal airway of the dog (Canis familiaris) and implications regarding olfactory airflow.
TLDR
A high-resolution view of the nasal airway of a large dog, using magnetic resonance imaging scans, which provides insight into the functional nature of canine olfaction and nondimensional analysis is used to show that the airflow within both the maxilloturbinate and ethmoidal regions must be laminar.

TLDR
Several novel morphological features in the nasal region of the hammerhead shark Sphyrna tudes are described, including a groove running anterior and parallel to the incurrent nostril, and the first simulation of internal flow within the olfactory chamber of a shark. Expand

TLDR
In front of the olfactory organ in the northeastern Pacific hagfishes Eptatretus stoutii, E. deani, and Myxine circifrons there is a valve that may function to direct water in between the o aroma laminae, and cilia show a tendency for a dislocation of one pair of the microtubules toward the center of the cilium.
