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 under flexible operant learning conditions.

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 Task Studio software, users can easily create their own tasks, and switch between a variety of different tasks 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 for example, projective capacitive, is too sensitive for rodent use generating a lot of erroneous data. Therefore, with the Touch Panel technology, users can expect to decrease both the rate of false negatives and false positives therefore greatly improving response accuracy.

Response speed: 10 msec (100 point/sec)
Interface: USB 1.1 or more
Power: 5V USB bus power (around 1.5W)
Accessory: sensitivity adjustment driver
Size – touch surface: 335 (W) x 255 (H) mm
Size – whole: 356 (W) x 310 (D) x 8 (t) mm

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 Task Studio is a suite of software applications that enable you to visually design and run behavior experiments. Operant task studio 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 trial sequentially or randomly. Trails designed by Trail builder are selected for execution. It is possible to set “phase”, “session” as you want.

    Task Scheduler File

    It is a task file designed by Operant Task Software V2. For one kind of operant task, it will need around 4 each of task scheduler files (shaping, training1, training2, evaluation, etc)

    • Trial Builder: Design Task
      Trial builder software is used to visually design operant task intuitively.
      By using flow-chart metaphor, every action of the operant task can be selected from action palette. Using connectors actions are interlinked.
      Trial builder allows you to easily configure external triggers that needs to be performed when the specified event occurs.
