(A) A representation of experimental protocols used for studying the safe TMT. The effect of injection of muscarinic receptor antagonist, scopolamine (SCOP), NMDA receptor antagonist (APV), and vehicle (ACFS) microinjected bilaterally into the NAcc shell (B) and the NAcc core (C) 15 min before presentation of saccharine on d 5. The Neophobia and AN are expressed in percentage of baseline consumption. ^**P < 0.01, as compared to their vehicle controls (post hoc Fisher test), significantly differ from the other groups.
