A Modular Behavioral Control Interface

Introducing the iCon, a simple-to-use behavioral control interface designed to support easy or complex experiments. With interchangeable analog and digital modules to fit the needs of any experimental paradigm, it can control most third-party behavioral chambers. The iCon connects directly to any TDT RZ processor and can be controlled with TDT’s Synapse software — resulting in high-bandwidth, precision control of behavioral hardware with real-time signal monitoring.

Transition Seamlessly from Subject Training to Research in a Single System

The iCon is flexible enough to work with your specific needs, whether you’re in the training process or further along into your research. Because of its modular design, the iCon can be easily reconfigured to help transition through each stage of your experimentation.

iH10 and iN10: High Voltage Interface

  • Synapse (software) configurable ports can act as either inputs or outputs.
  • Manual trigger buttons simplify testing and debugging of connected behavioral components.
  • Status lights make it easy to monitor component activity during sessions.



Synapse and Pynapse Integration

The iCon hardware seamlessly integrates with TDT’s Synapse software and its behavioral control Gizmo, Pynapse.

Pynapse has built-in features that simplify the configuration of behavioral paradigms and give users complete experimental control. Quickly design a simple task (e.g. self-administration of a reward) or a complex task (e.g. two-alternative force choice experiment) using the integrated Python coding. Pynapse displays all behavioral events, lever presses, rewards, and other experimental metrics in real-time to allow for rapid and efficient changes to task requirements in response to the subject’s skill set.

All this and more – perfectly integrated into your electrophysiology and/or fiber photometry project!
