Schematic of photometry and short-term taste memory assay. Mice were given one drop of water (∼1 μL), followed by 2.5 s of dry licks prior to the presentation of the sweet (5 mM AceK) or bitter (1 mM quinine) stimulus. The incorporation of the dry-lick window helps minimize the volume of water consumed and motivates the animals to continue performing for a water reward.
