Davenport. Pilot examination of SR and NR2B mRNA expression in gustatory cortex and amygdala. One rat given ~16-h access to 0.125% saccharin, control rat just water.

Golden, Ortega, Kwon (taught COC). Rats given a CFTP by several days of 24-h access to kool-aid, alternating solutions in high concentration saccharin (preferred, CS+/US+) or low concentration of saccharin (non-preferred, CS+/US-.)  CFTP is tested by 24-h 2-bottle preference between CS+/US- vs CS-/US-. Intraoral catheters were implanted. After 3 days of water infusions, rats were infused (10 ml /10 min)with either US+, CS+/US-, CS-/US-, or a novel kool-aid flavor.  One hour later, rats were prefused.  Olfactory bulb, gustatory cortex, amygdala, PBN, and NTS were processed for c-Fos.
