<i>Drd1a-</i>tdTomato BAC Transgenic Mice for Simultaneous Visualization of Medium Spiny Neurons in the Direct and Indirect Pathways of the Basal Ganglia

Abstract

### Introduction The expression of fluorescent proteins in defined subsets of neurons has become a powerful tool for neurobiology. One limitation of this technology is that the majority of BAC transgenic mice harnessing this technology use enhanced green fluorescent protein (EGFP) as the
