... brain function. We have initiated a study of zebrafish brain ventricle development and show here that the neural tube expands into primary forebrain, midbrain and hindbrain ventricles rapidly, over a 4-hour window during mid-somitogenesis. Circulation is not required for initial ventricle formation...

... of these mutants have a pericardial edema, the heart is slightly enlarged and the circulation is slightly reduced. However 1 day later, most of these mutants can hardly be distinguished from their wild-type siblings. In zebrafish, the circulation starts at approximately 24 hpf. Initially, the circulation...
