5. Example Pavlovian scripts

Pavlovian

Overview

Description of the Pavlovian program. Fill this in based on experimental purpose.

Key Features

• List key behavioral features.
• Timeout? Reinforcement schedule? LED/tone cues?

Code Highlights

// Add key snippet(s) here. Example:
fed3.run();           // Runs background updates
fed3.Feed();          // Dispenses a pellet

Usage

1. Upload this sketch to your FED3 using Arduino IDE.
2. Observe behavior and log file output.
3. Modify variables as needed for your experiment.

Logging

• Logs pellet events, poke activity, timeouts, and more depending on sketch.

Full Code

/*
  Feeding experimentation device 3 (FED3)
  Pavlovian Pellet Drop
  This script will delivery a conditioned stimulus, wait 5 seconds, and then drop a pellet
  After the pellet has been taken, it will complete a timeout of N seconds and repeat from the beginning
