Semi-Restraining System: TaskForcer

Train research animals faster and more effectively with TaskForcer, the advanced tool for operant behavior conditioning.

When research animals are stressed or distracted, training slows, and results may vary. Unlike other systems that allow rodents to move freely while performing tasks, the TaskForcer eliminates distractions and enhances data accuracy.

Train rats and mice in just three days with this innovative system!
  • The body-restraining system keeps subjects focused solely on the task.
  • The unique spout-lever combines operant task and reward, ensuring seamless training.
  • The modular design allows for easy customization and reproducibility.

Streamlined Training

TaskForcer’s body-supporting cylinder keeps rodents comfortably restrained and focused, allowing for faster training times.

Customizable Setup

Create the ideal training environment with customizable stimulus, reward, detection methods, and output/software options.

Integrated Imaging

Image simultaneously during behavior with the adjustable base mount, offering precise control of X, Y, and Z axes.

Detailed Steps for Customization

Customized Result


Choose Stimulus

Options include sound, light, odor, and visual cues.


Choose Reward

Dispense a consistent shot of water or liquid solution.


Choose Detection Method

Use licking detection, a lever unit, or the unique spout-lever.


Choose Output & Software

Interfaces, output boxes, and flexible TaskStudio software.

TaskForcer with Task Studio software is very easy to use compared to any other program. It is convenient to pull out a preconfigured program and hardware for different protocols.

The TaskForcer Story

Dr. Yoshikazu Isomura faced a common problem: It simply took too long to train head-fixed rats for his operant-conditioning studies.

His breakthrough was a body-supporting cylinder to calm rats and help them focus on the task while leaving their forelimbs free to move. He also developed methods to habituate rats to the system. The resulting high-throughput training structure was the foundation of the TaskForcer made by O’Hara.
