Comparison of microarray vs. deep sequencing data. miRNA expression analyses from two different expression profiling platforms. For both platforms, RNA was isolated, using Trizol LS, from superior and mid-temporal gyrus (Brodmann Areas 21/22) of nondemented elderly human brain. See text for more details.
