  • One-way ANOVA (F and p values are shown in Quantitative PCR column) was used to compare gene expression in three groups of cells: β-gal-positive neurons and β-gal-negative neurons from the same rats after a single injection of cocaine, and all neurons (NeuN-positive; NeuN+) from different rats after a single injection of saline. Fold-level changes are relative to control levels in NeuN + cells. Positive fold-level changes indicate higher levels, while negative fold-level changes indicate lower levels, than in NeuN + control samples.
