Semi Restraining System, TaskForcer

Spend less time training with the faster, simpler tool for operant behavior conditioning

When research animals are stressed or distracted, training can slow and your results may suffer variability. Unlike other systems that allow rodents to essentially “run free” while attempting to perform tasks at the same time, Amuza’s TaskForcer eliminates those distractions—and their effects on your data. Users can train rats and mice in just three days!


  • Body-restraining system keeps subjects focused solely on
    the task
  • Unique spout-lever combines operant task and reward
  • Modular design allows for easy, custom, reproducible results
TaskForcer is the must-have modular system for in-vivo electrophysiology and imaging. Our operant-behavior conditioning system is designed around your priorities. The only animal training system that was created to speed training, simplify configuration, and deliver consistent results to expedite your discoveries.

Whether your focus is neural imaging, recording, optogenetics, microdialysis, or behavioral study, TaskForcer frees you from cumbersome one-off fab-shop solutions and home-brew software. Simply consider your configuration requirements and create the TaskForcer solution that’s customized for you!

4 Steps to Customize your Research Animal Training Equipment
  1. Choose your stimulus.
    Whether the cue you need is sound, light, odor, visual… we’ve got you covered.
  2. Choose your reward.
    Our programmable supply unit dispenses a consistent shot of water or liquid solution.
  3. Choose your detection method.
    There’s licking detection. A lever unit. And our unique spout-lever which combines the operandum and reward in the same device.
  4. Choose your output and software.
    Interfaces, output boxes (in both 8- and 16-channel), and our flexible Task Studio software provide all the options you need.
Customized Result

Train research animals faster – in as little as 3 days

TaskForcer employs a unique body-supporting cylinder that keeps rodents comfortably cradled and gently restrained. Not only are they more relaxed and more focused on the task at hand (with facial and forepaw freedom to perform operations), but since they’re less distracted, research animals can be trained faster, too—often in as little as 3 days.

Customize your animal training equipment

Don’t waste your time designing custom apparatus—or waiting for your fabrication shop to try to build it. With Amuza’s TaskForcer, everything you need is right here. We offer a full suite of components that easily assemble into the custom configuration you need: Everything from water-dispensing pumps to a wide variety of stimulation units to interfaces, multichannel output boxes, and our easy-to-configure Task Studio software.

Use as much, or as little, as you need

With our full line of products and accessories, you can certainly start from scratch. But you don’t have to. If you have, a type of skull plate or sound generator you prefer, it will work with TaskForcer. So you get the best of everything: A custom solution and the flexibility of maximizing your existing equipment.

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.

Software that’s supported by us – to let you focus on your discoveries

You want to collect, analyze, and disseminate data—not provide software support! With our proven Task Studio software, simply assemble your trial with flowchart-like simplicity, and configure your triggers and executors with checklist-like ease. And if other researchers want to reproduce your findings, simply direct them to use Task Studio, too. This will save you from the headaches of “free software support” that you’d never intended to offer.
