This is the third replicate of selenate pre-Rx before glucose-induced flavor preference conditioning
Selenate Dosage
To test selenate attenuation of CFNP, rats will be injected with 1 ml/kg of 0.5 mg/ml Na2SeO4 in 0.15 M NaCl, (so 0.5 mg/kg selenate), 2 hours before conditioning.
- Sodium Selenate Na2SeO4 from 2021-2-16 from [Millipore-Sigma S8295-25G
- MW 188.95, CAS Number 13410-01-0, PubChem Substance ID 24899787
- 0.5 mg/ml Na2Se04 is 2.65 mM, or 7.95 mOsm (assuming complete dissociation into 2 Na+ and 1 SeO4- ions)
- So OK to mix 0.5 mg Na2SeO4 in 1 ml of 0.15 M NaCl, resulting in a 308 mOsm solution that is still near isotonic (300mOsM).

Agenda
Day 0 (04/29/2021): At 5pm Rats were weighed to determine their initial body weight, and their food and water was removed to begin the food and water restriction schedule.
Days 1-8 (04/30/2021-05/07/2021) Food/water restriction and training: Adult male Sprague-Dawley rats (N=16) were trained on a restricted food and water schedule for 8 days before conditioning. Each day at 1pm, the animals were weighed and given 23-25 grams of chow to maintain 90% body weight. After being weighed, animals were given access to two bottles, 0.05% saccharin and water. Initially, they were given 1hr to drink the solutions, and this was gradually reduced to 30 mins per day. Bottle positions were alternated each day.
Day 9 (05/08/2021): CS+ Conditioning
Day 10 (05/09/2021): CS- Conditioning
Days 11-? (05/10/2021-?): 2-bottle preference testing
