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. After 15 minutes mice are then injected with CNO (3mg/kg,10ml/kg, i.p) followed by LiCl (0.15M,20ml/kg, i.p) or isotonic saline after another 15 min.


Groups:

  • LTL: Exp group (predicted to show attenuated taste aversion)
  • LVL: + Control (expect to form taste aversion)
  • VTV: - Control (expect to not form taste aversion)
  • VVV: - Control (expect to not form taste aversion)


  • 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.
