Abstract
Single action sequence reinforcement protocol for mouse studies from Tang et al 2023.
Guidelines
Individual mice were subjected to a single session of protocol each day, with sessions following each other on consecutive days.
Materials
The white open field box is made of 410 x 400 mm white matte acrylic walls and a 410 x 400 mm white matte acrylic base. Note: A white open field was used instead of a grey open field to minimize habituation effects, which would lead to reduced initial spontaneous behavior during closed loop protocol.
Session 1 + Baseline
Session 1 + Baseline
Mice were placed in a white open field box for closed loop reinforcement protocol.
To acquire baseline behavior, individual mice were allowed to behave freely inside the box for 30 minutes on the first action A reinforcement session.
After initial behavior acquisition, closed loop reinforcement was initated by blue laser stimulation of VTA DA neurons were made available for 60 minutes.
Sessions 2 & 3
Sessions 2 & 3
90 minutes of closed loop reinforcement were made available for individual mice during sessions.
An extinction protocol was carried out comprising of 20-minute maintenance of reinforced behavior with laser availability, followed by 60 minutes of extinction of reinforced behavior without laser availability, followed by 20-minute re-acquisition of reinforced behavior with laser availability.
Selection for Action B 1 step
To select for action B, a repeat of the protocol described above for action A was performed starting on the day following extinction protocol of action A.
Contingency Degradation Protocol
Contingency Degradation Protocol
Upon completion of the reinforcement and extinction protocols for action B, a contingency degradation protocol was performed comprising of 20-minute maintenance of action B with laser availability, followed by 60 minutes of contingency degradation of reinforced behavior by triggering laser randomly, followed by 40-minute re-acquisition of reinforced behavior with laser availability for action B performance.
