“…Thus, some of the molecular components of the role of the PPC in memory encoding or consolidation have been identified by pharmacological means; i.e., by the microinfusion of a variety of drugs into this structure bilaterally at various times in the post-training period (Ardenghi et al, 1997; Izquierdo et al, 1997; Barros et al, 1998; Schröder et al, 2000; Luft et al, 2004; Alonso et al, 2005; Bonini et al, 2005); others by measuring biochemical changes in this structure at those times (Alonso et al, 2005; Izquierdo et al, 2007). They were found to participate, as said, beginning 60–90 min post-training, i.e., 60–90 min after the participation of the hippocampus and the basolateral amygdala in consolidation, and 30 or so min after that of the entorhinal cortex (Izquierdo and Medina, 1997; Izquierdo et al, 2006).…”
