Neuromast Optogenetics Reveals Rules of Spatial Encoding in the Zebrafish Lateral Line
… due to difficulties in stimulating individual neuromasts. To tackle this, I introduce a novel method in this thesis that combines single-neuromast optogenetics with whole-brain calcium imaging in zebrafish larvae. By optogenetically stimulating individual neuromasts, I observe that second-order …

A Hydrodynamic Sensory Antenna Used By Killifish for Nocturnal Hunting
… line consists of 18 stereotyped mechanosensitive neuromasts, each bordered by fleshy ridges. Each neuromast has a single axis of sensitivity along its longitudinal axis. The ridges bordering each neuromast form a channel parallel to the neuromast's axis of sensitivity. The ridges direct water …

CFD study of hydrodynamic signal perception by fish using the lateral line system
… for the Mottled Sculpin canal and superficial neuromast motions, in response to hydrodynamic signals. When the background flow was laminar, the neuromast motions induced by the stimulus signal at threshold had a spectral peak larger than spectral peaks resulting from the background flow induced …

Identifying Novel Molecular Mechanisms Underlying Lateral Line Organ Development in Sterlet
… 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 surrounding other animals. In …

Synapse Formation in the Zebrafish Lateral Line
… 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 of only one subpopulation, and this polarity-specific innervation arises independently of synaptic …

THE IN-VIVO IMPACT OF SMPX MUTATIONS DURING DEVELOPMENT AND DISEASE
… form. We also uncovered smpx expression in the neuromast mechanosensory hair cells of both anterior and posterior lateral line. The protein was localized throughout the cytoplasm of such cells and, as opposed to inner ear hair cells, also in the primary cilium. Loss-of-function experiments …

DISPERSAL MECHANISMS OF EMBRYONIC AND LARVAL BURBOT (LOTA LOTA)
… lota</em> larvae show a significant increase in neuromasts between 35 and 45 dpf, in both the anterior lateral line and posterior lateral line. Age significantly predicted neuromast abundance. These results help elucidate the developmental timeline of <em>L</em>. <em>lota</em> active dispersal …

The canonical Wnt signaling pathway affects regeneration of mechanosensory hair cells in Danio Rerio
… 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 demonstrated a robust ability to regenerate following damage. Previous studies …

Regulation of the development and regeneration of the zebrafish posterior lateral line
… decreased, and fewer average hair cells form per neuromast compared to heterozygous siblings. Following regeneration, foxg1aᵃ²⁶⁶ zebrafish show reduced proliferation and differentiation into hair cells. Coinciding with the reduction in average hair cell numbers we observed a reduction in central …

Protection effect of EC on radiation-induced cell death of auditory cell in vitro and in vivo
… 이용하여 방사선에 의한 청각기관의 변화를 보기 위해 지브라피쉬 신경소구(neuromast)의 변화와 그에 따른 EC의 효과를 확인하였으며, 이를 주사 전자 현미경하에서도 관찰하였다. 또한 백서를 이용하여 뇌간유발전이 청력검사를 시행하여 방사선에 의한 청력의 손실과 EC의 효과를 객관적 기능검사로 확인하였다. 세포 생존율을 측정한 결과 방사선의 양이 증가할수록 세포 생존율이 감소하였으며 20Gy의 방사선에 EC를 농도별로 처리한 결과 EC의 농도와 비례하여 세포 생존율이 증가하는 것을 확인할 수 있었다. FACS를 …
