Micro-Machined Flow Sensors Mimicking Lateral Line Canal Neuromasts
Fish sense water motions with their lateral line. The lateral line is a sensory system that contains up to several thousand mechanoreceptors, called neuromasts. Neuromasts occur freestanding on the skin and in subepidermal canals. We developed arrays of flow sensors based on lateral line canal neuromasts using a biomimetic approach. Each flow sensor was equipped with a PDMS (polydimethylsiloxan...
متن کاملComparative squamation of the lateral line canal pores in sharks.
The current study collected the first quantitative data on lateral line pore squamation patterns in sharks and assessed whether divergent squamation patterns are similar to experimental models that cause reduction in boundary layer turbulence. In addition, the hypothesis that divergent orientation angles are exclusively found in fast-swimming shark species was tested. The posterior lateral line...
متن کاملSource location encoding in the fish lateral line canal.
The position of a hydrodynamic dipole source, as encoded in a linear array of mechano-detecting neuromasts in the fish lateral line canal, was electrophysiologically investigated. Measured excitation patterns along the lateral line were compared to theoretical predictions and were found to be in good agreement. The results demonstrate that information on the position of a vibrating source from ...
متن کاملElectrical Responses from the Lateral-line Nerves of Fishes
The spontaneous discharge of impulses from the lateral-line nerves of trout and catfish has been examined. 1. Broken endings of nerve fibers supplying receptors of the lateral-lines of trout and catfish may be the source of a repetitive discharge of nerve impulses. 2. This injury discharge occurs more frequently in trout and may mask the spontaneous discharge from the receptor cells. Experiment...
متن کاملSensing Flow in the Aquatic World: The Fish Lateral Line as a Model System for Bioinspired Robotic Systems
Introduction Water motions provide a wealth a sensory information in the aquatic world. Fish exploit this information with their lateral line. This sensory system consists of up to several thousand receptive units, the so-called neuromasts, distributed across the entire body of the animal (1). Neuromasts are made up of a patch of sensory hair cells similar to those in the vertebrate inner ear, ...
