Developmental patterning of rod and cone photoreceptors in embryonic zebrafish.
Cone photoreceptors in the zebrafish retina are arranged in a crystalline lattice, with each spectral subtype at a specific position in the array; rod photoreceptors are inserted around the cones. Patterning events and developmental mechanisms that lead to the formation of the cone mosaic are not known. To begin investigating this issue, we examined the initial stages of opsin expression in zeb...
متن کاملDopaminergic neurons modulate GABA neuron migration in the embryonic midbrain
INTRODUCTION Neuronal migration is a fundamental process in the development of the central nervous system because neurons eventually dwell in regions distinct from their origin. From ventricular zones, neurons and/or neuronal progenitors navigate along diverse courses, radially and tangentially, to their final destination and integrate into specific brain circuits (Corbin et al., 2001; Hatten, ...
متن کاملDopaminergic neurons modulate GABA neuron migration in the embryonic midbrain.
Neuronal migration, a key event during brain development, remains largely unexplored in the mesencephalon, where dopaminergic (DA) and GABA neurons constitute two major neuronal populations. Here we study the migrational trajectories of DA and GABA neurons and show that they occupy ventral mesencephalic territory in a temporally and spatially specific manner. Our results from the Pitx3-deficien...
متن کاملEgr1 gene knockdown affects embryonic ocular development in zebrafish.
PURPOSE To identify the changes in zebrafish embryonic ocular development after early growth response factor 1 (Egr1) gene knockdown by Egr1-specific translation inhibitor, morpholino oligonucleotides (MO). METHODS Two kinds of Egr1-MO were microinjected separately with various dosages into one to four celled zebrafish embryos to find an optimal dose generating an acceptable mortality rate an...
متن کاملComprehensive catecholaminergic projectome analysis reveals single-neuron integration of zebrafish ascending and descending dopaminergic systems
Essential components of animal behaviour are modulated by dopaminergic (DA) and noradrenergic circuitry. In this study, we reveal at cellular resolution the complete set of projections ('projectome') of every single type of DA and noradrenergio neurons in the central nervous system of zebrafish larvae. The most extensive DA projections are established by posterior tubercular otp-dependent neuro...
