Total response magnitude (Rmag) to intra-TMJ injections of ATP on TMJ units recorded in superficial (upper panel) and deep laminae (lower panel) defined as ATP responsiveness from FS and sham rats under HE and LE conditions. Sample sizes: laminae I-II, HE-FS = 17, HE-sham = 18, LE-FS = 14, LE-sham = 14; lamina V, HE-FS = 11, HE-sham = 13, LE-FS = 10, LE-sham = 7 units. *P < 0.05, **P < 0.01 versus response to PBS; b = P < 0.01 versus sham group; + = P < 0.05, ++ = P < 0.01 HE- versus corresponding LE-treated group.
