    Med Associates Inc central reward receptacle
    Configurations used for optimising the DSST. (A) Schematic design of the chambers used in the visual discrimination manipulation. A central nose poke port was required to initiate each trial (shown as the red circle). Rats were then required to observe the central display for an image (white spider) and respond in a head entry <t>receptacle</t> either side (grey square) to receive a pellet reward. (B) Shows the schematic design of chambers used during the dynamic reversal manipulation. Each trial started with a response in the central nose poke that was followed by presentation of stimulus. The subject was then required to respond by pressing a lever. (C) For the optimised DSST configuration the front panel consisted of a speaker, 3 stimulus cue lights, an illuminated nose poke, two retractable levers, and a central reward magazine.

    Techniques Used:

    Dynamic reversal manipulation. Shows the dynamic switch protocol whereby rats ( n =8 males, n =8 females) were required to switch between the two rules after a fixed number of trials. The first rule was the cue light task requiring rats to respond at the location of a cue light by making a head entry in the correct head entry receptacle. The second rule required rats to respond only at one location and withhold responding to the location of the cue light. Each block consisted of 10 trials. (A) performance on the VCT over 12 blocks. (B) Performance over 12 blocks with 60 trials on each rule. (C) Performance over 12 blocks of 40 trials per rule. (D) Performance over 12 blocks with 20 trials per rule. Successful acquisition of a rule was determined by achieving 80% accuracy.
