Cover legend: This image displays a dense localization of fluorescently labeled perineuronal nets (green) around mouse hippocampal CA2 pyramidal neurons (red) and proximal neurites. Perineuronal nets are stained with Wisteria floribunda agglutinin, CA2 neurons are labeled using a mouse line expressing EGFP under control of the Amigo2 promoter (Gensat). Nuclei are stained with DAPI (blue). For more information, see the article by Carstens et al. (pages 6312–6320).
