Synapse Formation in the Zebrafish Lateral Line
… are matched for synapse formation. The zebrafish lateral line offers the opportunity for greater insight into this process. Hair cells in the lateral-line neuromast exist as two intermingled subpopulations, anteriorly and posteriorly polarized cells. Afferent neurons form synapses with hair cells …

Synaptic Specificity in the Zebrafish Lateral Line
… how synaptic specificity arises. The posterior lateral-line organ of larval zebrafish consists of polarized hair cells organized in discrete clusters known as neuromasts. Here I show that each afferent neuron of the posterior lateral line establishes specific contacts with hair cells of the same …

Performance analysis for lateral-line-inspired sensor arrays
The lateral line is a critical component of the fish sensory system, found to affect numerous aspects of behavior including maneuvering in complex fluid environments, schooling, prey tracking, and environment mapping. This sensory organ has no analog in modern ocean vehicles, despite its utility …

Zebrafish Posterior Lateral Line Organogenesis Regulation by Notch Signaling
… rosette‐shaped sensory organs in the zebrafish lateral line system. Notch cell autonomously induces apical constriction and cell adhesion downstream of Fgf signaling and organizes lateral line organs into rosettes independent of patterning cues normally provided by a Wnt/Fgf signaling system. We …

Artificial Lateral Line Canal System for Underwater Disturbance Sensing
… sensing using a micromachined artificial lateral line canal system. As a potential alternative to sonar, it offers a passive mode of detection, which could allow for the realization of stealth monitoring capabilities. An example would be for the real-time autonomous detection and tracking …

Identifying Novel Molecular Mechanisms Underlying Lateral Line Organ Development in Sterlet
In all fishes and aquatic-stage amphibians, lines of mechanosensory lateral line organs ('neuromasts' containing hair cells), distributed over the head and trunk, detect local water movement. Many species also have electrosensory lateral line organs that detect weak electric fields, such as those …

A flexible underwater pressure sensor array for artificial lateral line applications
… model, the operating conditions required for a linear sensor response are determined. This thesis ends with proof-of-concept underwater object and wave detection experiments demonstrating that the sensor can function as an artificial lateral line. The sensors exhibit a 1.38 . 10-³ fractional …

Regulation of the development and regeneration of the zebrafish posterior lateral line
… class of mechanosensory hair cells found in the lateral line (LL) system, allowing them to sense changes in water current. Unlike mammalian inner ear hair cells, zebrafish lateral line hair cells can robustly regenerate following damage throughout the life of the animal. Our work focuses on …

Neuromast Optogenetics Reveals Rules of Spatial Encoding in the Zebrafish Lateral Line
… performance. In this study, I use the posterior lateral line (pLL) of larval zebrafish to address this question. In the wild, the pLL must differentiate among a variety of hydrodynamic stimuli. However, understanding how fish distinguish between different water-flow stimuli has been challenging …

CFD study of hydrodynamic signal perception by fish using the lateral line system
The lateral line system on fish has been found to aid in schooling behavior, courtship communication, active and passive hydrodynamic imaging, and prey detection. The most widely used artificial prey stimulus has been the vibrating sphere, which some fish are able to detect even when the signal …

Design and fabrication of a MEMS-array pressure sensor system for passive underwater navigation inspired by the lateral line
… of such a pressure sensor system, namely the lateral line organ, a spatially-distributed set of sensors over a fish's body that allows the fish to monitor its hydrodynamic environment, influenced by the external disturbances. Through its ability to resolve the pressure signature of objects, …

The canonical Wnt signaling pathway affects regeneration of mechanosensory hair cells in Danio Rerio
… mechanosensory hair cells are also found in the lateral line system. The lateral line system senses variation in water current. Neuromast mechanosensory organs comprise the lateral line and consist of hair cells, supporting cells and mantle cells. In zebrafish, hair cells of the lateral line have …

Touch at a distance : underwater object identification using pressure sensors
… obstacles and maneuver, live fish also use their lateral line organ. The role played by the canal lateral line system is particularly important for hypogean fish, such as blind Mexican cave fish, who use it to avoid obstacles and navigate dexterously in complex environments. Similarly, pressure …

A Study of Asymmetry in Mosquitofish Populations in Polluted and Nonpolluted Environments Using a New Scale Staining Technique.
… of the characters studied, pectoral fin rays and lateral line scales, showed no asymmetry in these populations and therefore provided no data for comparisons. A third character, number of pores in the lateral line scales, showed asymmetry in all populations. Asymmetry was quantified in two ways: …
