Agenda
Rats Arrive (December 3, 2024)
Rats (n=4 male, n=5 female, littermates, DOB: 7-???-2024) transferred from GFP-TH breeding protocol to individual cages.
Day 0: Surgery (December XXX, 2024)
Chronic Intraoral Catheters implanted under isoflurane anesthesia. All rats receive carprofen (XXX mg/kg) pre-operatively and 1 day post-op.
Days 1 - 3: Recovery (December XXXX - XXXX, 2024)
Weigh rats daily. Ad lib food and water. Carprofen (XXX mg/kg) on first day post-op.
Days 5-7: Habituation (December XXXX - XXXX, 2024)
Rats given intraoral infusion of 6 ml dH2O over 6 min to habituate to infusion procedure
Food removed on last day of habituation.
Noncontingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Day 8: Conditioning day 1 (December XXXX, 2024)
All rats given intraoral infusion of 6 ml sucrose 5% over 6 min.
Contingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Food returned overnight.
Day 9: Recovery Day (December XXXX, 2024)
Food removed.
Noncontingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Day 10: Conditioning day 2 (December XXXX, 2024)
All rats given intraoral infusion of 6 ml sucrose 5% over 6 min.
Contingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Food returned overnight.
Day 11: Recovery Day (December XXXX, 2024)
Food removed.
Noncontingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Day 12: Conditioning day 2 (December XXXX, 2024)
All rats given intraoral infusion of 6 ml sucrose 5% over 6 min.
Contingent group: Half of rats injected with LiCl (0.15M, 12 ml/kg).
Food returned overnight.
Day 13: Recovery Day (December XXXX, 2024)
Food removed.
Day 14: Expression Test (December XXXX, 2024)
All rats given intraoral infusion of 6 ml sucrose 5% over 6 min.
Ten minutes after infusion, rats are overdosed with euthansol and transcardially perfused. Brains postfixed for 1-2 hours, then stored in 0.1M PB.
