Touch Panel: Automated Operant Chamber

High-throughput behavioral testing systems that enable real-time measurements of neural activity with unprecedented precision.

IR sensor technology improves accuracy of touch responses during operant behavioral testing.

Touch screen methods have become both an efficient and powerful tool to test cognition in rodents. Our Touch Panel operant chamber is fully automated with unique infrared (IR) sensors located at the top right and top left corners of the 15-inch touch screen. The IR sensors greatly improve the accuracy of recorded touch responses because there is no minimum force requirement to detect a response. Additionally, the Operant TaskStudio software, users can easily create their own operant tests, and switch between a variety of different operant tests within a single session.

  • IR sensor technology improves the sensitivity of detected touch responses improving the quality and reliability of your data.
  • Fully automated hardware and software improves the efficiency of data collection and removes experimenter bias.
  • The unique trapezoidal design makes it easier for subjects to focus on the desired task, decreasing learning time.
  • Compatible with neural recording techniques.
  • Compatible for mice/rats/monkeys/humans

How it works : What’s unique about the Touch Panel Operant Chamber

The Touch Panel IR technology is more accurate than other touch technology for rodents. The IR sensors within the touchscreen require no minimum activation force, meaning animals do not have to push the screen in order register a response. The touch screen technology that is in our smart phones (projective or electrostatic capacitance) for example,  is too sensitive for rodent use, generating a lot of erroneous data. With the Touch Panel technology, users can expect to decrease both the rate of false negatives and false positives, which greatly improves response accuracy.

What is electrostatic capacitance?

This is the technology our smartphones use. It is sensitive enough to be detected by the human finger, however, not sensitive enough to detect noke pokes by small rodents. 

The Touch Panel Operant system uses photobeam IR technology which greatly improves the sensitivity of response detection.

Software

Task Control Software | OperantTaskStudio V2

Operant TaskStudio is a suite of software applications that enable you to visually design and run behavior experiments. Operant TaskStudio can be configured easily to work with your hardware setup.

  • Development language: C++
  • OS: Windows 7 Professional, Windows 10 Professional
  • Operant Task Executor
    Operant task executor supports the execution of one or more trials sequentially or randomly. Trails designed by the Trail Builder are selected for execution. 

    Task Scheduler File

    A task scheduler file is a task file designed by the Operant TaskStudio Software V2. 

    • Trial Builder: Design Task
      Trial builder software is used to visually design a task scheduler file for your operant tests.
      Every action of the operant test can be selected from the action palette on the left hand side and dragged into the main space into a flowchart. Each action can be linked with connectors to trigger a sequence of events.
      Trial builder also allows you to easily configure external triggers that need to be performed when the specified event occurs.  For example, a cue sound when a reward is given.
