Ca(2+) plays important roles in animal development and behavior. Various Ca(2+) transients during development have been reported in non-neuronal tissues, mainly by using synthesized calcium indicators. Here we used GCaMP3, a genetically encoded ca...

Ascidian Ciona intestinalis tadpole larvae exhibit left-right asymmetry. The photoreceptors are situated on the right side of the sensory vesicle, and the tail curls along the left side of the trunk within the chorion. In tailbud embryos, the Ci-p...

Zebrafish is a good model for studying vertebrate development because of the availability of powerful genetic tools. We are interested in the study of the craniofacial skeletal structure of the zebrafish. For this purpose, we performed a gene trap...

Glycinergic neurons are the major inhibitory neurons in the vertebrate central nervous system. In teleosts, they play important roles in the escape response by regulating the activity of the Mauthner (M-) cells. Here we studied the contact between...

In the formation of the spinal network, various transcription factors interact to develop specific cell types. By using a gene trap technique, we established a stable line of zebrafish in which the red fluorescent protein (RFP) was inserted into t...
