(A) The rat’s brain atlas showing the PrL location as a small vertical bar. (B) The location of the PrL microinjection. The blue vertical bar represents the buried cannula placement. The spot area indicates the distributions of saline or the NMDA microinjections. The density of (C) c-Fos or (D) p-ERK in positive neurons/mm2 in the PrL for the control, MAMPH, PrL (+)/MAMPH, and PrL(–)/MAMPH groups.
