Tone-induced activation of ERKs and calcineurin in the ventromedial prefrontal cortex of CB1+/+ and CB1-/- mice. (A) Schematic drawing depicting the dissected area according to Paxinos and Franklin (2001). (B) Levels of phosphorylation of ERKs. (Photographs) Western immunoblots showing bands corresponding to phosphorylated forms of ERKs (P-p44 and P-p42) and to respective total ERK protein (p44 and p42). (Graphs) Densitometric quantification of tone-induced p44 and p42 ERK phosphorylation in CB1+/+ (open bars) and CB1-/- mice (filled bars), relative to respective no-tone mice (100%, dotted line). (C) Levels of calcineurin expression. (Photographs) Western immunoblots showing bands corresponding to calcineurin and to respective actin. (Graph) Densitometric quantification of tone-induced calcineurin expression in CB1+/+ (open bars) and CB1-/- mice (filled bars), relative to respective no-tone mice (100%, dotted line). N = 7-11 per group. Data expression and symbols are as in Figure 2.
