Hydrodynamic aspects of fish olfaction.
Flow into and around the olfactory chamber of a fish determines how odorant from the fish's immediate environment is transported to the sensory surface (olfactory epithelium) lining the chamber. Diffusion times in water are long, even over comparatively short distances (millimetres). Therefore, transport from the external environment to the olfactory epithelium must be controlled by processes t...
متن کاملClinical aspects of olfaction
The most important aims of this thesis were: (1) to investigate the prevalence of olfactory dysfunction in an adult Swedish population and to relate dysfunction to factors of possible impact on olfaction, (2) to present our experience with patients seeking medical attention for olfactory disorders, (3) to describe the relationship between detection and identification tests for olfactory disorde...
متن کاملBasic and clinical aspects of olfaction.
Disturbances of olfaction are a common occurrence in many neurological and neurosurgical patients and their correct diagnosis might be helpful in management and enhancement of quality of life. However, olfaction is seldom checked in most neurosurgical units and the "smell bottles" are often either absent or out of date. This chapter reviews systematically recent advances in our understanding of...
متن کاملOlfaction: How Fish Catch a Whiff
An elegant new study shows that multiciliated cells in the noses of aquatic vertebrates generate flow fields that help odor detection and processing.
متن کاملHydrodynamic Performance of Deformable Fish Fins and Flapping Foils
A computational study of fish fin hydrodynamics is being conducted concurrently with experimental analysis. The presence of a complex shaped moving boundary makes this a difficult proposition for computational fluid dynamics and here we use a Cartesian grid based immersed boundary solver designed to handle such flows in all their complexity. High resolution, high speed video of fish fin movemen...
