The computer recorded number of presses on the lever producing reinforcers and on the alternative lever, number of flap openings to the cubicle, number of reinforcers produced and collected, and the time of the events.
Recording was made of number of presses on the reinforcer-producing lever and on the alternative lever, number of reinforcers produced and collected, and the time of the events.
For each segment, total number of presses on correct and incorrect levers, total number of correct (with water present) and incorrect (no water present) openings of the door into the recessed cubicle, number of reinforcers delivered, and the time between consecutive correct lever presses (inter-response time, IRT) were recorded.
Number of lever presses on active and inactive levers, and number of injections per sessions were recorded.
For the lever-pressing tasks, numbers of lever pressing during one 30-minute session for both optogenetic rats and control rats were individually averaged for each day and were mapped to time-course curves.
To assess motivation and participation in the task phase, we set up models to analyze the effect of group, sex, and delay block on total number of trials initiated (nosepoke into food tray to initiate trial and presentation of levers) and total number of trials responded to (choosing a lever once presented).
We mean the lever with the numbers 1 to 10 on the round flywheel at the front of the machine.
The submitted data set contains responding on the active and inactive levers and the number of sucrose pellets for all three treatment groups across ten days of sucrose training.
The submitted data set contains responding on the active and inactive levers and the number of cocaine infusions for all three treatment groups across thirteen days of cocaine self-administration training.
For each segment, the total number of presses on the correct and incorrect levers as well as number of reinforcers delivered were recorded.
