show Abstracthide AbstractGene expression profiling of nuclei isolated from genetically defined neuronal subpopulations of the adult Drosophila brain. Overall design: Gene expression profiles were generated from nuclei isolated from all neurons (R57C10-GAL4), Kenyon cells (OK107-GAL4), and octopaminergic (Tdc2-GAL4) neurons in the adult Drosophila head using a method similar to INTACT (Deal and Henikoff, 2010; Steinner et al., 2012). Sequencing was performed with an Illumina HiSeq 2000.
