Abstract

Purpose: To compare the effects of reduced inhibitory neuron function in the retina across behavioral, physiological, and anatomical levels. Methods: Inhibitory neurons were ablated in larval zebrafish retina. The Ptf1a gene, which determines inhibitory neuron fate in developing vertebrates, was used to express nitroreductase. By exposing larvae to the prodrug metronidazole, cytotoxicity was selectively induced in inhibitory neurons. Visual phenotypes were characterized at behavioral, physiological, and anatomical levels using an optomotor response (OMR) assay, electroretinography (ERG), and routine histology, respectively. Nonvisual locomotion was also assessed to reveal any general behavio..
