Agenda
Mice In House Colony FosCreER X hM4Di (n=11 male DOB +/-, n=12 female DOB +/-)
Drug Preparation: Isotonic LiCl (0.15M,20ml/kg, i.p) followed by 4-OHT prepared at 5mg/ml (50mg/kg,10ml/kg, i.p) or Sesame oil vehicle (10ml/kg i.p) after 10 min.
Pre Treatment (8/18/23) 2 weeks before starting water restriction 4 groups:
1. Isotonic LiCl and 4-OHT, N=6
2. Isotonic LiCl and sesame oil, N=6
3. Isotonic saline and 4-OHT, N=6
4. Isotonic saline and sesame oil, N=5
Day 0: Water removed (2023-9-12)
Days 1 - 11: Water Restriction (2023-9-13 - 2023-9-23)
Weigh mice daily. Ad lib food. Water access on consecutive days at noon: 3h, 3h, 3h, 1h, 1h, 1h, 30min, 30 min, 10 min, 10 min, 10 min.
Mice given water bottle and empty bottle, alternating position.
In the afternoon (~4pm), mice will be given supplemental access to water for 30 min.
Day 12: Conditioning Day (2023-9-24)
Mice are given 10-min access to 0.125% saccharin solution, then injected with CNO (3mg/kg,10ml/kg, i.p) followed by LiCl (0.15M,20ml/kg, i.p) after 10 min
Groups: All mice receive CNO & LiCl injections
- JCE01-04: Female
- JCE05-08: Female
- JCE09-12: Male
- JCE13-16: Male
After injection, ad lib water returned overnight.
Day 13 - 24: Preference Tests (2023-9-25 - 2023-10-6 )
CTA acquisition and extinction was measured with 24-h, 2-bottle preference tests. Mice were given 24-h free access to both 0.125% saccharin and water bottles, alternating position for 7 days.
