... of cognitive specialization. We analyzed genome-wide brain gene expression during facial and pattern training for two species of paper wasps ( P. fuscatus , which has face recognition, and P. metricus , which does not) using RNA sequencing. We identified 237 transcripts associated with face specialization in P...

... by expressing the same genes as J. transcriptus males or whether novel brain gene expression patterns have evolved to produce a similar behavioral phenotype in the females of J. marlieri . This study used cDNA microarrays to investigate whether female J. marlieri and male J. transcriptus show conserved...
