生きているゼブラフィッシュ幼虫の眼球除去による神経支配依存性の成長と視覚系の発達を調べる

Overview

This article describes a surgical technique for removing eyes from living zebrafish larvae to study the impact of retinal input on optic tectum growth. It details the processes of larval anesthetization, fixation, and brain dissection, followed by immunohistochemistry and confocal imaging.

Methods Used

• Surgical removal of one eye from larval zebrafish.
• Anesthetization of larvae for humane treatment.
• Brain dissection for further analysis.
• Immunohistochemistry and confocal imaging for visualization.

Main Results

• Comparison of optic tectum growth in innervated vs. denervated conditions.
• Insights into the role of retinal input in neural development.
• Potential applications for understanding regeneration and degeneration.
