==Purpose==
==Purpose==
Attempt single-bottle single trial conditioning using a CS+ which is iso-preferred to water (Koolaid + 0.05% saccharin, based on Golden data from experiment GI -- see chapter 3 of Golden's dissertation).
Attempt single-bottle single trial conditioning using a CS+ which is iso-preferred to water (Kool-Aid + 0.05% saccharin, based on Golden data from experiment GI -- see chapter 3 of Golden's dissertation).
Will also characterize a US dose response using 0,4, or 8% glucose to determine a range of conditioning strengths (since KA + 0.2% saccharin + 8% glucose looks too strong to see any modulation by eg sodium buytrate).

* Weigh rats.
* 30 min access to CS+/glucose = 0.2% Koolaid + 0.05% saccharin + either 0% glucose, or 4% glucose, or 8% glucose.
* 30 min access to CS+/glucose = 0.05% Kool-Aid + 0.05% saccharin + either 0% glucose, or 4% glucose, or 8% glucose.
* At end of 30 min access, return ad lib food and (weighed) water.
