"Studied the general pattern of calretinin (CR) parvalbumin (PV) and calbindin (CB) immunoreactivity as well as morphological features and density of CR and PV immunoreactive (CR+ PV+) interneurons in the rat perirhinal cortex (PRC) and found the PRC possesses specific interneuronal equipment with unusually high proportion of CR+ interneurons."xsd:string
